MIT FILTER PRESS
The filter press operates on a simple yet effective principle: pressure filtration. Sludge is pumped into a series of chambers lined with filter cloths. As pressure builds, water is squeezed through the cloth, leaving behind solid particles that compact into dense “filter cakes.” These cakes are then removed, and the clean filtrate moves on for further treatment or discharge.
- Filter Plates: These form the chambers and are often made of durable plastic or steel.
- Filter Cloths: Acting as the sieve, they trap solids while allowing water to pass.
- Hydraulic System: Applies pressure to close the plates tightly.
- Feed Pump: Pushes the slurry into the press.
Benefit :
- High solids capture: Up to 75% or more with coagulant aids
- Compact sludge: Reduces disposal volume and cost
- Reliable operation: Especially in batch processes
- Customizable: Available in plate-and-frame, recessed chamber, membrane, and belt types.
Applications :
- Municipal wastewater plants for sludge dewatering
- Industrial facilities treating oily or chemical-laden effluents
- Water treatment plants removing algae, silt, and other particulates
- Landfill leachate processing, where contaminants must be isolated before discharge
