WIMA Belt Filter Press.

The WIMA belt filter press offers efficient sludge dewatering with high throughput and dry solids content while minimizing energy, water, and polymer consumption. Flocculated sludge is evenly distributed onto a horizontal pre-dewatering section, where free water drains through a screen. Guide plates and baffles aid this process, ensuring the sludge attains a stable consistency.

The sludge is then sandwiched between upper and lower belts and directed around a special dewatering roller. Gentle pressure and special seals prevent lateral sludge leakage, enabling dewatering from both sides. As the sludge stabilizes, the pressure is gradually increased. The sludge passes through several press rollers, removing most of the mechanically dewaterable water.

Remaining water is extracted through further pressure increase along the press path, until the dewatered sludge cake is discharged. The belts return under hydraulic tension and are automatically regulated, while spray nozzles continuously clean them.

This robust and user-friendly belt filter press ensures optimal dewatering results with minimal resource use, providing a sustainable solution for sludge dewatering
