If grinders are used and the screenings are left in the plant influent flow, they would contribute an additional 3 mg/L to 77 mg/L (average of 20 mg/L) of total suspended solids to the design plant influent TSS concentration. This would result in an average increase of 5 to 10% in the primary sludge quantity.

Accurate volumetric measurement of the thickener's inflow is vital to ensure the clarity of the recovered process water. Essentially the in feed flow rate can be controlled based on high clarity of the overflow. So the clearer the outflow, the faster the inflow feed rate which leads to optimised thickener throughput. Combined with the mass flow

the gravity thickening process. The model is based on an analysis of transport phenomena within the sludge layer during thickening. By using this new mathematical mode l to predict thickening behavior, design of thickeners as well as design for the thickening function of clarifiers can now be conducted on a wholly rational basis. The model

Therefore, Sludge Thickening Process is always looked upon as a cost effective related method that is used to remove more liquid content in order to increase the solid fraction. Sludge thickening using centrifugal force is one of the common processes that can be applied to reduce the water content and thus thickens the sludge.
