Improve Clarifier and Thickener Design and Operation

A design method for thickeners and clarifiers known as the batch flux curve technique was developed over 20 years ago, but still is not well-known in design and operating circles. An informal survey of major clarifier and thickener manufacturers found that none of the firms surveyed use this method for sizing and maximizing operating conditions.

Schreiber Clarifiers

Schreiber's Peripheral Drive Clarifiers are favored because of their ability to accomplish rapid sludge removal and continuous collection and removal of floatables. Instead of the typical center-drive high torque arrangement, Schreiber Clarifiers utilize the mechanical leverage and mechanical simplicity of a peripherally driven system.

Sludge Dewatering and Thickening

In the lower portion of the thickener is the sludge rake, which moves sludge to the hopper, where sludge is collected and compacted. Sludge can be thickened to 8-10% total solids. A pump then sends the sludge to the anaerobic digester. At the top of the basin is the scum collector and discharge. Sludge Thickening and Dewatering Page 2 of 18

Sludge Thickening

The primary objective of sludge thickening is to concentrate the solids, thus reducing the volume of sludge. Thickeners may increase the solids concentration by a factor of 2–5 and produce a clarified liquid effluent. Thickening is accomplished by either gravity or dissolved-air flotation. A gravity thickener is shown in Figure 10. The ...
