PCL-Series
High-Rate DAF System
High-Rate DAF System for Large-Scale Industrial Wastewater Treatment
FRC’s PCL-Series DAF removes solids, oils, and FOG using high-rate flotation, crossflow plate packs, and in-tank sludge thickening for high-capacity wastewater applications.
The PCL-Series High-Rate Dissolved Air Flotation (DAF) system from FRC Systems is engineered for maximum performance in high-flow industrial wastewater environments. With a vertical, space-saving design and integrated crossflow plate packs, the PCL-Series efficiently removes Total Suspended Solids (TSS), Fats, Oils, and Grease (FOG), and other contaminants, delivering drier sludge and clearer effluent with a reduced footprint.
In the PCL-Series DAF system, clarified effluent is recirculated and saturated with air using an angled air dissolving tube and non-proprietary recycle pump. This creates a whitewater stream filled with microbubbles. When mixed with influent wastewater, the bubbles attach to suspended solids, causing them to rise. A crossflow plate pack improves separation by increasing effective surface area. At the top, floated solids are skimmed off while a dewatering grid thickens sludge, and clarified water exits below.

PCL FAQ
Q: What industries benefit most from the PCL-Series DAF?
A: The PCL-Series is ideal for industrial sectors with high flow and solids content, including food processing, petrochemical refining, and pulp & paper.
Q: How does the crossflow plate pack improve performance?
A: The plate pack increases the effective separation area, allowing higher hydraulic loading and improved solids capture within a smaller footprint.
Q: Does the PCL-Series use proprietary parts?
A: No. It uses ANSI-standard recycle pumps and readily available components, minimizing maintenance costs and downtime.
