An appropriate flocculant can significantly improve the dewatering ability of sewage sludge. In order to assess its effectiveness, the measurement of capillary suction time (CST) and the measurement of the specific resistance to filtration (SRF) of a cake are most often used ( Sawalha and Scholz, 2010 ).

Flocculants: Selecting Polymers and Jar Testing Procedures

Flocculants are used to form large macroflocs which can be easily transported to the surface by the rising air bubbles and subsequently removed. As in the case of gravity clarifiers, the use of flocculants can increase throughput capacity (by increasing particle rise rate) and prevent suspended solids carrying through into the effluent.

Brennfloc flocculants improve clarification by gathering the fine coagulated particles (or pin floc), increasing floc size, and increasing these particles¡¯ settling or rise rates. Flocculation is the second step in clarification and can greatly improve the plant operation by speeding up separation and clarity.

Water | Free Full-Text | Could Plant-Based Flocculants

Due its high water content, sewage sludge dewatering is not just a simple operation; rather, it is a challenging process and a costly management task. Its final handling is usually preceded by several dewatering steps, and among them is the conditioning process known as the flocculation stage, which is carried out using synthetic chemical reagents. Despite the abilities of these additives to ...

polymer flocculants

Polymer Flocculants

The water content of sludge cake after dewatering treatment is usually ca. 80 %, and the volume of sludge can be reduced to 1/10 the original volume of sludge. Polymer flocculants which are capable of reducing water content of sludge more than before are strongly requested in the treatment of dewatering sludge because of cost reduction.
