Sludge dewatering: filter press cycle time and cake solids

We want to reduce sludge volume and hauling cost. Our filter press cycle is long and the cake is still wet.

What cycle time, pressure and cake solids do you achieve?

• Conditioning chemicals
• Feed solids and filter cloth
• Blow-down and air-drying
• Labor required per cycle

A before/after number would be very useful for the business case.
