Sludge Filtration

PremierSolutions Filtration Process Design

Sludge Filtration System:  A filter press or belt press dewaters the sludge from the Dissolved Air Flotation (DAF) system, thereby reducing the volume and disposal costs. The slurry from the DAF system is continuously discharged into a common conditioning feed tank.  The filtrate is recycled back to the equalization tank, and the solid cake, containing 30% to 40% moisture, is usually disposed of off-site at a local landfill.
