Floater disc

As its name implies, the floater disc traps floating solids and prevents them discharging with the clarified centrate. The centrate dips under the disc before di.seharging, thus allow ing solids with air attached 1o have more time to deaerate. 

Floating solids build up on the surface of the pond between the floater disc and the beach. Eventually the floating solids build up sufficiently to be carried on the back of the heavy solids scrolling up the beach,... 

The precise design of the test decanter needs to be adapted to the process to be tested. Oil/water separation requires a three-phase design, solvents require flameproof electrics, effluents need abrasion protection. While manufacturers will have a pool of test decanters of basic design, it is essential that they are able to adapt them for special application testing. For instance, they will have special decanter conveyors that can be introduced, when necessary, and will be able to make small changes to them where necessary, such as the addition of a floater disc for floating solids. With a test decanter it is essential to be able to adjust bowl speed, differential and pond depth to suit particular applications or difficulties as they arise.
