Krofta supracell clarifier

Based on the test results, improvements in the hydraulic characteristics of the plant alone are very attractive, with the Krofta Supracell clarifier in a secondary flotation position (see Figure 27.12). 

Many pilot plant operations have been conducted by KEC through Krofta Apparatebau G.M.B.H., Germany, under direct supervision of Mrs Elisabeth Hurst-Gaul, Manager. The use of a Krofta Supracell DAF clarifier for secondary clarification in the activated sludge treatment plant has been concluded to be feasible. This chapter summarizes the results of her investigation. 

Expansion of the existing aeration basins and secondary sedimentation clarifiers is costly and sometimes unaffordable. The easiest facility change will be addition of a secondary flotation unit, such as a Krofta Supracell or its equivalent, as shown in Figure 27.12.
