The RAD system is what separates the DAF unit from a typical API type Oil/Water Separator. The RAD system is used to create water that is saturated with dissolved air and introduces this air/water mixture into the DAF flotation/separation chamber at the influent point. Once in the separation chamber, the dissolved air begins to come out of
The WPL Dissolved Air Flotation system is a purely physical process which operates on a simple design philosophy. Incoming effluent may require pre-treatment as necessary; for example the addition of chemical coagulant(s) and/or flocculant(s) may be required.
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation …
A study on the fluid dynamics of two-phase flow in a Dissolved Air Flotation (DAF) unit using CFD − Computational Fluid Dynamics is presented. An evaluation of different approaches to the multiphase, turbulence and drag models, as well as different boundary conditions to model the surface of the DAF tank were performed.

DAF FOR WASTEWATER TREATMENT Kimberley Davies, Environmental Engineer, Goulburn Valley Water ABSTRACT As part of the determination of a strategy for the upgrade of Shepparton Wastewater Treatment Complex, Goulburn Valley Water have undertaken a Dissolved Air Flotation (DAF) trial on secondary effluent from the plant.
Dissolved Air Flotation Theory of Operation. If you are unfamiliar with basic DAF separator design principles, a review of the "Dissolved Air Flotation Theory of Operation" might prove helpful.This basic document covers Stokes' law and other basic separation concepts.
Dissolved Air Flotation (DAF) is an effective process used for the separation of suspended solids, oils and greases, and other insoluble impurities from water.

Nov 16, 2015· The Rectangular Coalescent Flotation Units (FRC) developed by TORO EQUIPMENT SL are designed for the optimum treatment and reduction of the concentration of solids in wastewater.
Flotation units can remove up to 95% of free oil and are most commonly used as a process step downstream of gravity separation to meet discharge limits or to reduce the load on filtration systems. Inlet oil content should not exceed 1000 ppmv and should preferably be below 300 ppmv.

Reason being, the PWL design is optimized for treating wastewater heavily loaded with solids that require significant amounts of free surface area for flotation and separation. PWL units are rectangular in shape and built wider and longer as the free separation area requirement increases.
There are various types of flotation processes that use dispersed gas bubbles as the flotation agent. The primary difference between the various types is the manner in which the gas bubbles are formed. Dissolved air flotation (DAF) For more information, see: Dissolved air flotation.
