Belt Filter Press
Sludge Dewatering System
Compact Solution for Automated Sludge Dewatering
FRC’s stainless-steel belt press reduces sludge volume with stacked dewatering zones and continuous belt cleaning for low-maintenance operation.
The FRC Belt Filter Press is a high-throughput, automated dewatering system designed to reduce sludge volume and handling costs in industrial and municipal wastewater treatment. With a compact, vertically stacked design, this press delivers consistent, dry sludge cakes with minimal operator intervention—making it ideal for facilities processing oily, fatty, or particulate-rich sludge.
Conditioned sludge enters the belt press and moves through a series of dewatering zones. It first passes through the gravity drainage zone, where free water drains out. Then it moves into a wedge zone and is gradually compressed between two belts. In the final stage, high-pressure rollers extract the remaining water, producing a dry sludge cake. The belts are continuously cleaned with automated spray bars, allowing for consistent, unattended operation and reduced maintenance.
