ANDRITZ Filter Press Systems in India | Advanced Solid-Liquid Separation Solutions

ANDRITZ Filter Press Systems are advanced solid-liquid separation solutions designed for efficient sludge dewatering, lower cake moisture, improved filtrate quality and reduced disposal costs. Featuring automated sidebar and overhead filter press technologies, they deliver reliable, energy-efficient performance with scalable automation and Industry 4.0 integration.

Technical Configurations & Frameworks

Sidebar Filter Presses (SE & ME Series)

ANDRITZ sidebar filter presses are designed for operations where quick installation, reliable batch dewatering, and low maintenance costs are critical. In this design, the entire plate pack is supported by two heavy-duty steel side rails, creating a compact system that fits easily into facilities with limited space

​

How it works: Slurry is pumped into the filter chambers, where solids are retained on the filter cloth while the filtrate passes through and is collected. Once the filtration cycle is complete, an automated plate shifter opens the plates sequentially, allowing the dewatered filter cake to discharge efficiently for easy handling and disposal

Structural Mechanics

The entire filter plate pack is supported by sidebars along the frame.

Sizing & Capacities

Plate dimensions scale from 470 x 470 mm for pilot configurations up to 2,000 x 2,000 mm for massive industrial lines. The series reliably handles filtration pressures from 7 bar up to 30 bar.

Best Suited For

Standard to heavy-duty applications including sand and gravel processing, metal hydroxide sludges, chemical pigments, and industrial wastewater.

Key Advantage

Highly modular architecture with optimized structural weight, resulting in lower capital expenditure (CAPEX) and faster delivery times for Indian projects.

Benefits

  • Simple design

  • Customer-oriented process solutions through modular designs

  • Lower costs due to optimized structural weight

  • From manual to fully automatic operation

  • High operating availability and reliability

  • Maintenance-friendly

  • Easily upgradable in terms of volume and filtration area

Overhead Filter Presses (AE, A4, & MiningMaster ME4 Series)

ANDRITZ overhead filter presses are designed for high-capacity and demanding separation applications where maximum equipment uptime is essential. In this design, the filter plates are suspended from a strong, heavy-duty top beam instead of being supported by side rails.
 

During operation, the plate-shifting and hydraulic transport mechanisms are mounted on the overhead beam. Slurry is fed through the plate pack under high pressure, forming dense filter cakes. Once the filtration cycle is complete, the plates open from above, allowing the filter cakes to drop directly into a collection bunker or conveyor below for easy handling and removal.

Structural Mechanics

The filter plates are suspended from a heavy-duty top-beam. Shifting mechanisms operate entirely from above.

Sizing & Capacities

Built for massive production scale (up to 2,500 x 2,500 mm plate sizes) and severe operating environments.

Best Suited For

High-throughput, abrasive, or highly sticky slurries such as iron ore, coal tailings, and large-scale municipal sludge dewatering.

Key Advantage

Complete, unobstructed side access to the plate package. This dramatically simplifies routine filter cloth replacement and allows for easy mechanical washdowns.

  • Unmatched productivity thanks to fast cake discharge system and large filtration area

  • Flexible design for evolving needs

  • Intelligent operation optimizing performances and reducing energy consumption

  • Greener footprint with reduced oil consumption and improved energy efficiency

Advanced Internal Plate Geometries

The internal plate configuration dictates the filtration physics. ANDRITZ supplies three primary plate types to the Indian market to match your exact slurry profile:

Chamber / Recessed Plate Filter Presses

A fixed-volume design where the solids accumulate inside the recessed chambers purely through feed pump pressure. Ideal for standard slurries with high initial solids concentrations.

Membrane Squeeze Filter Presses

Features flexible, inflatable membranes on the plates. After the initial chamber fill, the system injects high-pressure water or air (up to 30 bar squeeze pressure) to mechanically compress the cake, squeezing out trapped capillary water.

Plate and Frame Units

Utilizing separate plates and frames, this traditional setup is optimized for ultra-fine clarification and pre-coating applications within the Indian food, beverage, and pharma refining sectors.

Intelligent Automation: Metris addIQ for Filter Presses

To reduce operator intervention and maintain consistent cycle times, ANDRITZ integrates the Metris addIQ control platform directly with the filter press hydraulics and feed systems. Available in Flex, Prime, and Dynamic configurations, the system provides clear process visibility and better control over filtration performance:

Real-Time Cake Moisture Tracking

Smart sensors measure filtration resistance and filtrate flow trends dynamically. Instead of operating on arbitrary timers, the system stops the feed pump the exact moment target cake dryness is reached, cutting average cycle times by up to 8%.

Fast Cake Discharge

Automated control of the closing hydraulics and fast plate-shifting modules minimizes dead time between batches, yielding up to a 40% reduction in mechanical cycle duration.

Predictive Diagnostics

Continuous tracking of hydraulic fluid quality, feed pump pressure, and cloth blinding trends provides maintenance alerts before operational downtime occurs.

Driving Zero Liquid Discharge (ZLD) Efficiency in India

With the Central Pollution Control Board (CPCB) enforcing strict Zero Liquid Discharge (ZLD) regulations across textile, chemical, and pharmaceutical industries in India, efficient mechanical dewatering has become essential.
 

By using an ANDRITZ Membrane Filter Press, plants can achieve cake dryness levels of more than 35–45% solids through mechanical dewatering. The more water removed during the high-pressure membrane squeezing stage, the lower the load on downstream thermal evaporation systems. This helps reduce steam consumption in Multi-Effect Evaporators (MEE) and Agitated Thin-Film Dryers (ATFD), resulting in lower overall operating expenditure (OPEX) for the plant.
