[Case Study of Food Factory] Adoption of a Single-Plate Filter Press for Activated Sludge Treatment

The amount of coagulant used has been significantly reduced! The decrease in moisture content has also led to a reduction in the disposal costs of the dewatered cake.

A certain food factory was considering replacing its aging dewatering machine. There were issues such as high running costs due to the use of two types of polymer coagulants (cationic and anionic), a high moisture content in the dewatered cake leading to increased disposal costs, and a preference for the amount of wash water used to remain roughly the same as the current level. Based on customer hearings and dewatering tests, we proposed the CS type (single cloth filter). After implementation, the amount of coagulant used was significantly reduced, and the decrease in moisture content also led to a reduction in disposal costs for the dewatered cake.
