4. Classification & Applications

4.1 Plate-and-Frame Filter Press

Pressure: 0.3–3 MPa

Applications: Compressible/non-compressible slurries (<10% solids).

4.2 Chamber Filter Press

Advantage: Higher pressure (up to 4.5 MPa), no frame required.

4.3 Belt Filter Press

Features: Continuous operation, low energy consumption.

Applications: Municipal sludge dewatering.

4.4 Diaphragm Filter Press

Moisture Reduction: Cake humidity ≤50% after squeezing.

5. Installation & Maintenance

5.1 Installation

Concrete foundation with anchor bolts.

Hydraulic oil: ISO VG 20–40 (operating temperature > -5°C).

5.2 Maintenance

Daily Checks: Lubrication, filter cloth integrity.

Annual: Hydraulic oil replacement + system flush.

Critical Notes:

Never operate with insufficient filter plates.

Avoid overpressure (>4.5 MPa) to prevent plate deformation.

6. Troubleshooting

Issue 1: Misalignment During Operation

Solution: Reverse feed pipe orientation (180°) to counterbalance forces.

Issue 2: Chain Derailment

Solution: Replace 7-link chains with 3-link chains to prevent twisting.

7. Industry Applications

Sludge Treatment: Reduces moisture to 65–80%.

Emerging Tech: Ultra-high-pressure vertical filter presses (residual oil <5%).

Process Flow:
Sludge → Chemical Conditioning → Filter Press → Cake Disposal (Landfill/Incineration)
