Fats, oils, and grease (FOG) represent one of the most challenging contaminants in food processing wastewater. These substances can form surface scum, clog pipes, interfere with advanced biological treatment processes, and create environmental hazards if not properly removed before discharge.
Animal fats, vegetable oils, cooking grease, butter, dairy products, and petroleum-based lubricants from processing equipment all contribute to FOG loading in wastewater.
Untreated FOG causes pipe blockages, pump failures, odour problems, surface scum formation, and interference with advanced biological treatment processes.
Most jurisdictions enforce FOG discharge limits of 10-15 mg/L, with some requiring levels below 5 mg/L for direct discharge to sensitive receiving waters.
Dissolved Air Flotation (DAF) is the industry-standard technology for FOG removal, achieving 90-99% removal efficiency through microbubble attachment and surface skimming.
Our DAF systems generate microbubbles (20-50 microns) that attach to oil droplets and fat particles, creating buoyant flocs that rise to the surface for removal.
Polymer preparation and continuous dosing systems enhance flocculation and improve FOG capture rates, especially for emulsified oils and stable fat dispersions.
PLC-controlled systems with variable speed drives and level sensors ensure consistent performance with minimal operator intervention. Integrates with SCADA platforms for remote monitoring.
Screening removes large solids and protects downstream equipment from damage and fouling.
Balancing tank smooths flow variations and provides consistent loading to the DAF system for optimal performance. See equalization tanks and the sizing calculator.
pH adjustment and coagulant/flocculant addition via chemical dosing systems destabilise emulsions and enhance FOG agglomeration.
Microbubble flotation separates FOG from water, with surface skimming for sludge removal.
