As renewable diesel production continues to expand across North America, operators face a familiar challenge: how to effectively manage wastewater streams with extremely high oil, grease, and solids loading. One renewable diesel refinery processing recycled animal fats and used cooking oils turned to FRC Systems for a reliable, chemical‑physical wastewater solution designed to meet strict discharge limits while recovering valuable oils. This case study highlights how a properly engineered dissolved air flotation (DAF) system helped the facility achieve consistent compliance, operational reliability, and improved oil recovery. The Challenge: High‑Strength Wastewater from Renewable Feedstocks The refinery operates at approximately 10,000 barrels per day, converting recycled fats, oils, and greases into renewable diesel fuel. While these feedstocks support sustainability goals, they also generate wastewater with exceptionally high contaminant concentrations. Influent wastewater characteristics included: Flow rate of 80,000 gallons per day Total Suspended Solids (TSS): 9,700 mg/L Fats, Oils, and Grease (FOG): 7,400 mg/L The wastewater originated from both Accidental Oil Containment (AOC) and Continuous Oil Containment (COC) areas across the site. Without effective treatment, these streams posed a risk to downstream processes and regulatory compliance. Treatment Objectives The refinery required a treatment system capable of: Consistently meeting discharge limits of 300 mg/L TSS and 100 mg/L FOG Handling variable oil loading without process upsets Maximizing oil recovery for reuse or disposal Operating reliably in an industrial Oil & Gas environment To meet these objectives, the system needed to be robust, flexible, and engineered specifically for high‑FOG industrial wastewater. The Solution: Chemical‑Physical Treatment with FRC DAF Technology FRC Systems designed and supplied a chemical‑physical wastewater treatment system centered around a high‑performance DAF unit. Key Equipment Supplied PWL‑15 DAF System F‑3 Stainless Steel Flocculator Integrated chemical dosing equipment Pneumatic and electrical control systems Equalization (EQ) tank upstream of treatment This configuration allowed for optimal coagulation, flocculation, and flotation of oils and suspended solids prior to discharge. How the DAF Process Works The treatment process begins with wastewater entering an equalization tank, where flow and loading are stabilized. Coagulants and polymers are then added, promoting the formation of larger, more floatable floc particles. Within the PWL‑15 DAF, dissolved air is released as microbubbles that attach to oils and solids, lifting them to the surface for removal. The clarified effluent exits the system while concentrated float is skimmed for oil recovery. Design Highlights Hydraulic surface loading rate designed at 1 gpm/ft² Solids loading rate of 5 lb/ft²/hr DAF sizing based on both hydraulic and solids loading to ensure stable operation These design parameters ensure the system can handle peak loadings while maintaining consistent effluent quality. Results: Reliable Compliance and Oil Recovery Following installation, the FRC DAF system successfully reduced influent contaminants to within required discharge limits: Parameter Influent Discharge Requirement Flow 80,000 gpd — TSS 9,700 mg/L 300 mg/L FOG 7,400 mg/L 100 mg/L In addition to regulatory compliance, the refinery benefited from: Improved operational stability Efficient removal of free and emulsified oils Recovery of skimmed oil for proper handling Reduced burden on downstream treatment systems Why This Matters for Renewable Fuel Producers As renewable diesel and biofuel facilities continue to scale, wastewater treatment systems must evolve alongside production demands. High‑FOG waste streams require more than generic treatment solutions—they demand purpose‑built DAF systems engineered for industrial performance. This project demonstrates how FRC Systems combines process expertise, proven equipment, and application‑specific design to help Oil & Gas and renewable fuel producers protect infrastructure, meet environmental requirements, and operate with confidence.

During the project development process, you will eventually narrow down a list of potential dissolved air flotation (DAF) system manufacturers. At this stage, the critical task is to determine which manufacturer and system best meet your specific needs. How Should You Choose? Whether you are an engineer specifying equipment for a client, a plant owner addressing wastewater treatment challenges, or someone seeking a deeper understanding of wastewater process equipment, this guide aims to provide a comprehensive understanding of key DAF system design considerations. By exploring mechanical and process design elements in this series, you will gain valuable insights to evaluate DAF systems . This knowledge will enable you to identify superior designs and, most importantly, make an informed purchasing decision. Given the significant investment, selecting the right DAF system is essential. 1. Aeration System: The heart of the DAF unit. The aeration systems are the central component of a DAF, representing one of the largest capital and maintenance expenses. Therefore, understanding its design and functionality is crucial. Below is a breakdown of common pump types used in DAF aeration systems and their respective advantages and limitations. Multistage Impeller Pumps These pumps are often referred to as "whitewater pumps". They draw atmospheric air (or compressed air) into the pump, where impellers mix/shear the air with water to create micron-sized bubbles that dissolve into the solution. While effective in generating whitewater, multistage impeller pumps pose several challenges in wastewater environments: Low Solids Tolerance: These pumps are prone to failures when handling oily, stringy, or gritty materials, which are common in wastewater applications. Cavitation/Airlock: In general, these pumps are not designed to handle entrained air. Air can collect at the eye of the impellers which can cause loss of flow (airlock) and binding. Air being introduced to the pump for “white water” generation can cause cavitation leading to increased energy usage, increased noise/vibration, and in more extreme instances cause damage to seals, bearings and impellers. Dependency on Manufacturer-Specific Components: These pumps tend to be “special order” or made in low quantities. Typically, these pumps must be sourced directly from the manufacturer which can lead to high replacement cost and extended downtime due to limited availability or long lead times. Multistage impeller pumps can generate quality “white water”; however, they lack the robustness in a wastewater environment where solids, grit and oily materials are prevalent. With the high associated maintenance costs and lower reliability, most DAF manufacturers have moved away from the Multistage Impeller Pump. Regenerative Turbine Pumps Regenerative turbine pumps are another type of pump often marketed as "whitewater pumps". These pumps are often characterized as providing high discharge pressures associated with positive displacement pumps with the versatility of a centrifugal pump. They utilize a turbine-like impeller with radially oriented blades/vanes to draw in atmospheric or compressed air and mix with water to create microbubbles. When choosing a Regenerative Turbine pump for a DAF application it is important to consider: High Pressure Capability: These pumps can generate high pressures and low flows in a compact design. They can operate at discharge pressures of 90-120 psi in DAF applications while being resistant to cavitation and other ill effects of air entrained fluids. Clean Liquid Requirement: Due to tight internal clearances, these pumps typically require liquids with minimal abrasives or solid content, limiting their suitability for wastewater treatment. Limited Parts Availability: Popular models, such as those manufactured by Nikuni, often have very small supplier networks, leading to limited options in accessing quick replacement parts. Several manufactures utilize regenerative turbine pumps for “whitewater generation” on their DAF units, and their compact footprint make them a popular choice for upgrades of older Multistage technology. Tight tolerances and poor solids handling make them less suitable for certain wastewater environments and care should be taken to ensure proper application. End-Suction Centrifugal Pumps End-Suction Centrifugal pumps are produced by many pump manufacturers and are available in a variety of materials and configurations that can be adapted to a wide variety of applications. Due to the large variety in available pumps, there is a high degree of versatility across various industries, including food processing, oil refining, and chemical manufacturing. As with any pump selection, application is important. Here are some important considerations when evaluating a system using an end suction centrifugal pump. Simplified Whitewater Generation: In most DAFs that use an end-suction centrifugal pump for “whitewater” generation, the pump is utilized only for the pressurization of the recycle stream. The air and water are mixed in a separate vessel or saturation tube, meaning the pump is only doing what it was design for (pumping). This ensures that the pump can be selected for high efficiency and reliability. In some designs, manufacturers will use the pump in a similar manner to the Multistage pump where atmospheric air (or compressed air) is injected at the pump suction and the pump is used to dissolve the air. When the pump is utilized in this manner, it is prone to the same Cavitation/Airlock issues as the Multistage Pump. Adaptability: These pumps can be selected based on the application to handle a wide variety of liquids (with or without solids) and can be fitted with various materials and alloys for corrosive environments. Manufacturer Choice: Unlike specialized whitewater pumps, the end-suction centrifugal pump is typically not mixing the air in water. This allows more choice in manufacture and style of pump. Some DAF providers can work with the end user to select a pump that aligns with their preferred manufacturer/plant standard providing improved access to parts and service. By assigning the task of whitewater generation to a static tube or vessel, end-suction centrifugal pumps focus solely on pressurization, enhancing reliability and efficiency. When evaluating DAF systems, the aeration system reflects the manufacturer's design philosophy. Prospective buyers should inquire about the reasoning behind the selected pump type and its suitability for their specific wastewater treatment needs. 2. Controls and Automation: Enhancing Operational Simplicity The operational efficiency of a DAF system often hinges on its control and automation features. A well-designed system should be intuitive and user-friendly, akin to the seamless functionality of modern smartphones. Unfortunately, some DAF systems rely on overly complex operational procedures and have limited automation to reduce costs. This typically leads to increased labor, frustration, and hidden expenses. Often these systems require frequent operator intervention and manual procedures which take more time and require more knowledge from the operator: Start/Stopping the system based on incoming flow. Make regular adjustments to the DAF aeration system to achieve “whitewater” generation. Manually adjust chemical dosing rates based on changing flows and/or pH. Check the system for faults and evaluate performance based on visual inspection. In contrast, a well-automated system streamlines operations significantly by: Automatically starting and stopping the treatment system as determined by incoming flow and tank levels. Automating the aeration features such as low-pressure detection, system warm-up and off-cycle air purging. Automatically adjust chemical dosing rates based on flow rate to the system and pH. Report and alarm system faults and provide warnings for reduced system performance. Trend and store data for system flows, tank levels, pH turbidity, chemical consumption, and alarms. When considering a DAF system, request details its operating procedure and automation. This will provide insights into its usability and the time/labor necessary to operate it. A system with intuitive controls not only saves time but also reduces operational errors and long-term costs. 3. Materials of Construction When selecting a DAF system, durability is paramount. The harsh environments that DAF systems are exposed to demand robust materials to ensure long-term performance and minimize replacement costs. Let’s explore the most common options for tank construction, along with their advantages and limitations: Concrete Steel-reinforced concrete basins are commonly used in large municipal wastewater treatment plants. These basins are robust and leak-resistant but come with high costs due to the extensive civil work required, including excavation, steel reinforcement, concrete forming, and coating. Additionally, because they must be built on-site, concrete DAF basins are not typically practical for industrial facilities. Polypropylene Polypropylene is favored by some manufacturers for its lower material cost, decent strength, and broad chemical resistance; however, it has drawbacks. Exposure to extreme temperatures or UV radiation can degrade the material, causing discoloration and cracks. At temperatures below 32°F, it becomes brittle and prone to cracking. Furthermore, polypropylene’s degradation over time makes refurbishment rarely viable. Most manufacturers offer a limited warranty of around 10 years for polypropylene tank structures. Epoxy-Coated Carbon Steel Epoxy-coated carbon steel combines the strength of steel with the corrosion resistance of an epoxy coating, making it suitable for applications with high Total Dissolved Solids (TDS). However, in industries like food processing, this material is less reliable. Free fatty acids present in floating sludge can erode epoxy coatings, exposing the steel to rust and compromising structural integrity. While initially perceived as a cost-effective alternative to stainless steel, achieving comparable strength and corrosion resistance often makes epoxy-coated carbon steel similarly expensive. Stainless Steel Stainless steel is widely used in DAF tank construction due to its durability and versatility. Its natural chromium oxide layer prevents rust, allowing it to withstand temperatures from -320°F to 1500°F. Stainless steel is well-suited for both indoor and outdoor applications, and modifications can be easily made without the need for recoating. Tanks made from stainless steel can remain structurally sound for decades, retaining a high resale value and often being refurbished for continued use. However, stainless steel does come at a higher initial cost and may not perform well in environments with high chloride concentrations, which can cause pitting or corrosion. 4. Sludge Thickening Mechanisms The core function of a DAF system is to remove solids and oil contaminants from wastewater. Sludge disposal is one of the largest costs of operating a DAF system. Achieving dryer sludge reduces the sludge volume which increases efficiency and reduces disposal costs. Sludge consistency depends on several factors, with the largest being the chemical processes used to treat the wastewater. That said, a carefully engineered design will include features that can increase sludge dry solids performance. Sludge Dewatering Grid A dewatering grid is a stationary framework of angled steel plates installed at the water’s surface. This grid locks sludge in place as it rises, allowing it to dewater before skimmer blades push it toward the sludge ramp. Retention in the grid ensures higher dry solids content, resulting in less watery sludge. Without a dewatering grid, sludge may accumulate near the ramp and get forced back into the water, undoing any prior dewatering. Speed Adjustable and Time Adjustable Skimmer System Varying the speed of the skimmer system on a DAF unit can influence the dry solids content of the sludge. If the skimmer runs too quickly it can create turbulence which can resuspend solids causing carry over in the effluent. A skimmer system that runs too slowly allows the sludge blanket to overthicken which can cause the same issue. An optimal speed should remove the last 10-15% of sludge from the surface of the DAF. In applications where the sludge volume produced is low, it may not be necessary to run the skimmer continuously. Turning the skimmer off intermittently will allow the sludge blanket to thicken and dewater producing a dryer sludge. A system with the ability to run the skimmer at operator adjustable intervals can improve the dryness of the sludge without requiring operator intervention. Easily Adjustable Effluent Weir The water content of the DAF sludge is directly influenced by the level of the water inside the DAF vessel. In most DAFs this level is set with adjustable weirs. If the weir is too high, the skimmer system removes more water with the sludge. If the weir is too low the sludge can overthicken causing resuspension of solids and carryover in the effluent. A weir system that is quick and easy allows for optimization of the water level in the DAF which improves sludge dryness. By incorporating these features, DAF systems produce thicker sludge, leading to significant cost savings. Thicker sludge requires less storage, smaller dewatering equipment, and reduced chemical usage for filtrate reprocessing. When evaluating DAF systems, ask manufacturers how their designs optimize sludge consistency. Key questions include: What mechanisms ensure drier, thicker sludge? How can operators adjust sludge thickness to meet process requirements? By prioritizing these features, you can select a DAF system that balances performance, reliability, and cost-efficiency. 5. Dissolved Air Distribution: Why Methodology Matters The way whitewater is generated and distributed into the incoming wastewater stream has an impact on floc formation and flotation within the DAF vessel. Let’s compare two common approaches. Vertical Saturation Tank Configuration Some DAF manufacturers utilize a vertical saturation tank paired with a specialty whitewater pump and a diaphragm valve assembly to generate and inject whitewater. While this method can be effective, it has notable drawbacks: Excess Air Issues: The vertical saturation tank is designed to vent undissolved air from the top. However, some undissolved air escapes through the side-mounted discharge line, entering the flotation cell. This can cause large bubbles to enter the flotation cell, disrupting the sludge and immersing solids back into the water. Limited Coverage: Often these systems rely on a single dissolved air injection port into the wastewater stream immediately before it enters the DAF. This single injection point can distribute whitewater unevenly, resulting in inconsistent bubble coverage. Additionally, the large stream of white water injected at one single location can cause shear forces on the newly formed floc, breaking them apart typically requiring additional polymer. Slow Saturation: Start-up procedures often require time for whitewater to disperse across the DAF Cell. Manuals often recommend waiting 5-10 minutes before initiating treatment, delaying operational workflows. Angled Saturation Tube and Whitewater Manifold Configuration In contrast, systems using an angled air saturation tube and a whitewater distribution manifold offer several advantages: Complete Air Removal: Excess air escapes from the elevated end of the angled tube, ensuring only dissolved air enters the flotation cell. This eliminates large bubbles, maintaining stable sludge flotation. Even Distribution: Whitewater manifolds feature multiple injection ports strategically placed across the width and height of the DAF tank. Additionally, some white water can be injected at the time of floc formation when the DAF is paired with a Pipe Flocculator Reactor. This design ensures uniform microbubble distribution throughout the wastewater, enhancing separation efficiency and preventing overloading in specific areas. Rapid Saturation: With multiple injection points, these systems saturate the tank in under 60 seconds, significantly reducing start-up times and improving overall productivity. Reduced Footprint and Complexity: When properly configured the Angled Saturation Tube has an incredibly high air to water contact area relative to the size of the Saturation Tube. This results in extremely high saturation efficiency in a small footprint. Additionally, with no need for level sensors, automatic relief valves, proprietary aeration valves or other moving parts, complexity is kept to a minimum. Key Takeaway: Design Details Matter When evaluating DAF systems, take a close look at the dissolved air distribution design. Ask the manufacturer: How does the system manage excess air? What measures ensure even whitewater distribution? How long does it take to saturate the tank and begin treatment? Does the system rely on complex components? These details can make the difference between a smooth operation and one plagued by inefficiencies. 6. Application-Specific Design: A Tailored Approach Materials Selection Consider the example of a cattle processing plant, where wastewater is laden with abrasive, gritty solids. A typical DAF system with a cast iron recycle pump might initially seem cost-effective but would fail prematurely due to abrasive wear. A better choice would be a pump with a CD4MCu casing, offering higher hardness and resistance to abrasion. Thoughtful materials selection prevents costly downtime and replacement expenses. Understanding the application and tailoring the equipment to that application leads to a reliable, trouble free system. Process Engineering The application also dictates critical engineering parameters, such as: Hydraulic Surface Loading Rate: The rate at which wastewater flows through the DAF system’s effective separation area. Solids Loading Rate: The rate at which the DAFs free separation area is loaded with solids. Air-to-Solids Ratio: The ratio of dissolved air relative the solids being removed by mass. For instance, primary poultry solids separate more easily than biomass solids from an activated sludge system. Using the same design parameters for both would result in an oversized poultry DAF and an undersized biomass separator—wasting resources in one case and failing to meet performance requirements in the other. Questions to Ask When selecting a DAF system, don’t hesitate to ask: Why was this configuration chosen for my application? What material upgrades are available to address specific challenges? Explain the calculations behind system sizing and performance metrics? A manufacturer’s ability to provide clear, application-specific justifications reflects their expertise and ensures you receive a system optimized for your needs. Conclusion At face value, A DAF is like any another piece of industrial equipment—they’re an investment you want to make only once and have years of trouble-free operation. But the truth is, not all designs are created equal. With this guide, you now have a clearer understanding of the critical design elements that differentiate one DAF unit from another. Let’s summarize the key questions you should address with a DAF manufacturer before making a decision: What type of DAF recycle pump is used, and why? What materials are selected for tank construction? What mechanical measures are included to ensure effective sludge thickening? How is dissolved air distributed throughout the DAF tank? What are the operating procedures for the system? What specific design considerations have been made for your application? A reliable DAF manufacturer should be able to answer each of these questions thoroughly, providing clear justifications for their design choices. If a manufacturer struggles to articulate the reasoning behind their approach, it could indicate a lack of precision in their engineering process. On the other hand, a manufacturer who can confidently and thoughtfully discuss these topics is more likely to be a dependable partner in your project. Once you’re satisfied with the manufacturer’s explanations, take a closer look at their track record. A company with limited project experience may rely heavily on theoretical designs, which might not perform as well in real-world conditions. For a significant capital investment like a DAF, proven solutions are essential. Whether you’re an engineer designing a system or an end-user evaluating options, remember that choosing the right DAF is a decision you only want to make once. Take the time to ensure it’s the right one. If you’d like to discuss a specific wastewater application where a DAF system might be a fit, feel free to reach out to us—we’re here to help.

Step-by-Step Guide to Aeration Control This instructional video demonstrates how to set and balance the aeration controls on an FRC Dissolved Air Flotation (DAF) system. The goal is to generate stable, high-quality whitewater. Whitewater—the air-saturated recycle stream—is essential for effective solids flotation. Key Steps for Setting Aeration Controls Set Aeration Valves : Begin by adjusting the aeration valves on the DAF tank to 50% open. Ensure that all ports are uniform. Open Manifold Valves : Next, open the manifold valves to 100%. This action engages the recycle pump. Monitor Pump Pressure : It is crucial to check that the recycle pump discharge pressure remains below 90 psi. This ensures the system operates within safe limits. Adjust Pressure Regulator : Set the pressure regulator to 10 psi higher than the recycle pump. This adjustment helps maintain optimal performance. Fine-Tune Aeration Valves : Finally, fine-tune the aeration valves to achieve the target recycle pump pressure. This step is vital for optimal system performance. With these adjustments, the DAF system produces consistent microbubbles that spread across the tank surface. Fully saturated water takes on a “skim milk” appearance, signaling optimal whitewater conditions. This leads to reliable separation, lower operating costs, and consistently cleaner effluent. Understanding the Importance of Whitewater Whitewater plays a crucial role in the efficiency of a DAF system. It enhances the flotation process, allowing for better separation of solids from liquids. The quality of whitewater directly impacts the overall performance of wastewater treatment systems. When whitewater is properly generated, it leads to improved treatment outcomes. Facilities can achieve regulatory compliance more easily and reduce operational costs. This is particularly important for industrial and municipal facilities that face stringent environmental regulations. Benefits of Effective Whitewater Generation Enhanced Separation : Properly aerated whitewater improves the flotation of solids, ensuring they rise to the surface for removal. Cost Efficiency : By optimizing the aeration process, facilities can lower energy costs and improve the overall efficiency of their wastewater treatment systems. Regulatory Compliance : High-quality effluent is essential for meeting environmental regulations. Effective whitewater generation helps facilities stay compliant. Conclusion In summary, mastering the aeration controls of a DAF system is vital for producing high-quality whitewater. By following the outlined steps, facilities can enhance their wastewater treatment processes. This leads to better separation, lower costs, and compliance with environmental standards.
