Quick answer: A wastewater filter press dewaters sludge from municipal and industrial treatment plants into a cake of roughly 60–75% moisture (drier with membrane squeeze) that can be landfilled, composted or incinerated, while returning clear filtrate to the plant. Small chamber presses with polypropylene plates suit plants producing a few tonnes of dry solids a day; larger or membrane presses are chosen as volume or disposal cost rises.
Wastewater Filter Press – Efficient Dewatering Solution for Industrial and Municipal Sludge
- High Dewatering Efficiency: Optimized plate design speeds up cake formation and achieves lower residual moisture, making sludge reduction easier.

Buyer FAQ
How does a filter press reduce sludge disposal cost?
By dewatering sludge to a dry cake it sharply cuts weight and volume, so you haul and dispose of far less material.
Can it handle municipal and industrial sludge?
Yes. With the right cloth and optional membrane plates it handles both, including polymer-conditioned biosolids.
How do I size a wastewater filter press?
Size on kilograms of dry solids per day and cycles per day, not on wastewater flow. Cake volume per cycle equals the chamber volume, so plate size and count follow once daily dry solids and cycle time are known.
Does the sludge need conditioning?
Usually yes. Biological and hydroxide sludges are conditioned with polymer or lime/ferric so they filter in a reasonable cycle time and release from the cloth.
