High Pressure Membrane Filter Press

SINOU, a reliable manufacturer and supplier from China, provides high-performance High Pressure Membrane Filter Press for global customers. This equipment integrates chamber filtration and membrane secondary squeezing technology, specially designed for high-standard deep dewatering.

It uses high-strength reinforced membrane filter plates and stable high-pressure hydraulic system to fully squeeze residual moisture, greatly reducing cake moisture content. The whole machine supports fully automatic operation, with stable performance, low failure rate and easy maintenance.

We provide customized filtering area, plate size, pressure level and control mode to meet different sludge properties, treatment capacity and working conditions, delivering efficient, safe and reliable solid-liquid separation solutions.

What is High Pressure Membrane Filter Press?

1. Core Definition

High Pressure Membrane Filter Press is an upgraded high-efficiency solid-liquid separation equipment. It adds elastic membrane squeezing function on the basis of ordinary chamber filter press, using high-pressure water/gas to inflate the diaphragm filter plate for secondary deep squeezing, to get drier filter cake.

2. Key Working Parameters

Filtering pressure: ≤0.6 MPa

Membrane squeezing pressure: ≤1.0 MPa

Working temperature: -10 ~ 90℃

Max hydraulic protection pressure: 29 MPa

Max compaction pressure: 25 MPa

Oil cylinder stroke: 750 mm, cylinder diameter: 320 mm

Hydraulic station power: 4.0+2.2 KW

3. How It Differs From Ordinary Chamber Filter Press

Ordinary filter press: Only rely on feeding pressure to filter sludge, filter cake moisture is higher.

High-pressure membrane filter press:

First filter sludge by feeding pressure

Then inject high-pressure medium into diaphragm plates, plates expand and squeeze sludge tightly

Discharge more bound water, filter cake drier, moisture 5%-15% lower

4. Nozzle & Structural Features

Feed inlet: DN100; cleaning & discharge port: DN65; hydraulic pressure port for diaphragm squeezing: DN50

Filter plate thickness: 70/80 mm (high-strength reinforced for high-pressure squeezing)

Filter cake thickness: fixed 40 mm, stable deep-dewatering effect

Filtering area range: 100–320 ㎡, full-range high-pressure squeezing capacity

5. Main Advantages

1. Higher squeezing pressure (≤1.0 MPa), deeper dewatering, drier filter cake

2. High-strength thickened filter plates, pressure-resistant for long-term heavy-duty operation

3. Wide adaptability for hard-to-dewater sludge: mining tailings, chemical sludge, concrete slurry, oily sludge

4. Low transportation & disposal cost for dry cake, better environmental compliance

6. Simple Summary for Product Title

High-Pressure Membrane Filter Press = High-pressure squeezing type filter press, using diaphragm secondary extrusion to achieve lower-moisture sludge dewatering, suitable for high-standard industrial solid-liquid separation projects.

FAQ

Q1: What is the difference between diaphragm filter press and ordinary chamber filter press?

A: Diaphragm filter press adds high-pressure membrane squeezing function. It first filters by feeding pressure, then uses high-pressure water/gas to squeeze sludge again, making filter cake drier (moisture 5%-15% lower). Ordinary chamber filter press only relies on feeding pressure for filtration.

Q2: What is the maximum working pressure of your diaphragm filter press?

A: Filtering pressure ≤0.6 MPa, membrane squeezing pressure ≤1.0 MPa, max hydraulic compaction pressure 25 MPa, hydraulic protection pressure up to 29 MPa.

Q3: What is the filter cake thickness of this machine?

A: Standard filter cake thickness is 40 mm; filter plate thickness is 70/80 mm with high-pressure resistance design.

Q4: What temperature range can the equipment work in?

A: Working temperature is -10℃ ~ 90℃, suitable for most industrial sludge treatment environments.

Q5: What size of filtering area can you provide?

A: Standard range from 100㎡ to 320㎡; we can customize larger models according to your needs.

Q6: What are the nozzle sizes of the machine?

A: Feed inlet DN100, cleaning port & discharge port DN65, hydraulic pressure port DN50, flange standard GB/T9115-2000 PN1.6.

Q7: Can this machine work automatically?

A: Yes. It supports fully automatic operation including plate closing, feeding, squeezing, plate pulling and cake discharging, reducing manual labor greatly.

Q8: What kind of sludge is this machine suitable for?

A: Widely used for mining tailings, chemical sludge, concrete batching plant sludge, municipal sewage sludge, oily sludge and other hard-to-dewatering materials.

Q9: How long is the service life of filter plates?

A: Our reinforced polypropylene diaphragm plates have strong pressure and corrosion resistance, service life up to 5-8 years under normal operation.

Q10: Do you provide customized service?

A: Yes. We can customize filtering area, plate size, voltage, automatic mode and matching feeding pump system according to your working conditions.

Q11: What is the power of the hydraulic station?

A: Standard hydraulic station oil pump motor power is 4.0+2.2 KW.

Q12: What after-sales service do you offer?

A: We provide online technical guidance, installation manual, spare parts supply and long-term after-sales support.
