FRC Systems DAF Scum Collector 320 Dissolved Air Flotation Solids Separator

OVERVIEW

Large industrial Dissolved Air Flotation (DAF) scum collector and solids separator system, designated "Daft Scum Coll 320," engineered and integrated by FRC Systems International, LLC (Gainesville, Georgia). This is a complete, large-scale DAF clarifier scum collection and solids removal system used in industrial wastewater treatment operations. The system features a heavy-gauge steel rectangular clarifier basin with integral inclined screw/paddle conveyor mechanism for continuous automated removal of floated solids (scum) from the DAF flotation surface. Complete with drive motor and gearbox, FRP grating operator walkway platform with steel stair access, multiple large-diameter flanged influent/effluent piping connections, spherical air/pressure vessel, solenoid valve control package, Danfoss controller, Eaton Cutler-Hammer safety disconnect switches, and all associated instrumentation and controls.

DAF systems work by dissolving air into pressurized water and releasing it at atmospheric pressure inside a flotation tank, causing suspended solids, fats, oils, and greases (FOG) to float to the surface where they are continuously skimmed by the collector mechanism and removed as a concentrated sludge stream. Ideal for food and beverage processing, rendering plants, poultry and meat processing, pulp and paper, industrial laundry, municipal wastewater, and any facility requiring high-efficiency suspended solids and FOG removal from process wastewater.
