FRC has been the trusted engineer to help manage the wastewater treatment needs for this Canadian based top ten worldwide dairy processor as they grow and expand across North America.
This particular facility generates over 360,000 gallons of wastewater per day. The original wastewater treatment system design consisted of a biotower, a Continuous Waste Activated System (CWAS) system, and a clarifier. Without proper pretreatment, Fats, Oils, and Grease (FOG) was able to enter the biotower, which destroyed the biomass, disrupting the CWAS system downstream. The clarifier was also hydraulically overloaded, resulting in poor performance.
The FRC solution was to install a Dissolved Air Flotation (DAF) unit as a pretreatment step and to increase biological treatment capacity by installing a Moving Bed Biofilm Reactor (MBBR) system prior to the CWAS system. The MBBR system was designed with future expansion in mind and will eventually replace the CWAS system. Following biological treatment, FRC installed a secondary DAF unit for biomass separation. FRC was able to provide a complete turnkey solution, including the incorporation of controls, monitoring and automation into the existing Supervisory Control And Data Acquisition (SCADA) system.
