Automated Filter Press Manufacturer: High-Efficiency Dewatering Solutions for Industrial Sludge
Fully automated filter presses with PLC control, automatic plate shifting, and integrated cake discharge. Built for 24/7 operation in mining, wastewater, and industrial applications.
What Is an Automated Filter Press?
An automated filter press is an advanced solid-liquid separation system designed to minimize manual intervention while maximizing dewatering efficiency. Unlike manual filter presses, automated models feature:
- Automatic plate shifting – No manual labor required for opening/closing
- PLC-controlled operation – Programmable sequences for consistent results
- Integrated discharge systems – Automated cake removal and collection
- Remote monitoring – Real-time performance tracking via HMI touchscreen
Loway’s automated filter presses are engineered for continuous industrial operation, reducing labor costs by up to 60% while improving throughput and cake dryness.

- Extended Lifespan: Prevents blinding and prolongs the life of your filter media.
Working Process of Automatic Filter Press
The automatic filter press system consists of multiple interconnected stages, each designed to ensure effective and consistent separation of solids and liquids.
Plate Closing: The hydraulic system applies a pressing force of 0–30 MPa to tightly seal the filter plates.
Slurry Feeding: A high-pressure plunger pump injects slurry into the filter chambers at 0.6–2.0 MPa.
Filtration: Liquid passes through the filter cloth, while solid particles form a filter cake with a typical thickness of 25–50 mm.
Membrane Squeezing (Optional): In membrane filter presses, compressed air or water expands an internal elastic diaphragm to achieve secondary squeezing, significantly lowering moisture content.
Automatic Discharge: A plate shifting system automatically opens the filter plates, allowing cakes to fall off by gravity.
Cloth Cleaning: High-pressure spray systems remove residual particles, maintaining filtration efficiency.

Frequently Asked Question
Have More Questions? Our technical team is ready to provide detailed, personalized guidance.
Q1: What does “automatic” cover in your filter press?
Automation includes PLC-controlled fill, pressurization, timed filtration, automatic cloth wash/shaker, plate opening and cake discharge—minimizing manual intervention.
Q2: Can you customize plate size and material?
Yes. We offer multiple plate sizes and materials (PP, PS, membrane plates) and tailor designs for chemical resistance and cake release.
Q3: How much labor can I save with an automated filter press?
Most clients report 50-60% reduction in direct labor costs. A manual filter press typically requires 2-3 operators per shift, while an automated system can run with just 1 supervisor monitoring multiple units.
Q4: What's the difference between automatic and semi-automatic filter presses?
Semi-automatic: Requires manual plate opening/closing; automated feeding and pressing only.
Fully automatic: Complete cycle automation including plate shifting, cake discharge, and cloth washing. Zero manual intervention during normal operation.
Q5: Can automated filter presses handle abrasive materials?
Yes. We use reinforced polypropylene plates and high-wear filter cloths rated for mining applications. Expected plate life: 5-8 years; cloth life: 2,000-3,000 cycles with proper maintenance.
Q6: How low can the cake moisture content be with your Membrane Filter Press Automation?
With our advanced Membrane Filter Press Automation, we can typically achieve cake moisture content in the range of 15% to 30%, depending on the specific material and its compressibility. The secondary squeezing phase significantly surpasses the dewatering limits of standard chamber filter presses.
Q7: Can I integrate this with my existing plant automation?
Absolutely. Our PLC systems support Modbus RTU/TCP, Profibus, and Ethernet/IP protocols. We provide integration support to connect with DCS or SCADA systems.
Q8: What is the typical ROI of an Automated Filter Press compared to a manual one?
The return on investment (ROI) is primarily driven by three factors: labor savings, reduced disposal costs, and increased throughput. By automating the entire cycle, you eliminate the need for continuous operator presence, and the consistently lower cake moisture content directly translates to lower costs for transporting and disposing of filter cake. Most industrial operations see a rapid ROI due to these combined efficiencies.
Q9: What maintenance is required for the automatic plate shifting system?
The automatic plate shifting system is designed for minimal maintenance. Key requirements include routine lubrication of the chain and guides, and periodic inspection of the hydraulic system seals. Our smart control system provides predictive maintenance alerts, allowing you to address potential issues before they lead to downtime.
