Efficient Sludge Dewatering with Recessed Plate Filter Press

Short Description:

The chamber filter press uses filter cloth as a medium to separate solids from liquids, making it suitable for a wide range of particle sizes. The cloth is spread across the surface of the filter plates and supported by grooves within the plates. When the plates are clamped, the cloth acts as a seal, creating individual filter chambers between each pair of plates. During operation, the slurry enters through the central inlet, and under feeding pressure, the filtrate passes through the cloth and exits via the drainage channels.

Based on the filtrate discharge method, chamber filter presses are categorized into open flow and closed flow types.

Product Description

Filter presses are widely used to separate suspended solids from liquids in various industrial processes.

Main Components of a Filter Press:

1. Frame – The main supporting structure
2. Filter Plates – Chambers where the filtration occurs
3. Manifold System – Includes piping and valves for slurry distribution and filtrate discharge
4. Filter Cloth – The key filtering medium that retains solids

Compared to other dewatering technologies, filter presses offer the driest cake and the clearest filtrate. Optimal performance depends on proper selection of filter cloths, plate design, pumps, and accessories such as precoating, cake washing, and squeezing.

Holly Filter Press models include: Fast-opening filter press; High-pressure filter press; Frame filter press; Membrane filter press.

Multiple types of filter cloth are available: Multifilament polypropylene; Mono/multifilament polypropylene; Monofilament polypropylene; Fancy twill weave filter cloth.

These combinations allow customization for different sludge types and treatment goals.

Working Principle

During the filtration cycle, slurry is pumped into the press and evenly distributed into each chamber formed by the filter plates. Solids accumulate on the filter cloth, forming a cake, while the filtrate (clean water) exits through the plate outlets.

As pressure builds inside the press, the chambers gradually fill with solids. Once full, the plates are opened, and the formed cakes are discharged, completing the cycle.

This pressure-driven filtration method is highly effective for achieving low moisture content in sludge.

Key Features

✅ Simple structure with linear design, easy to install and maintain
✅ Uses high-quality, internationally recognized components for pneumatic, electrical, and control systems
✅ High-pressure dual-cylinder system ensures secure plate closing and efficient operation
✅ High level of automation and environmental protection
✅ Can be connected directly to filling machines via air conveyors for streamlined processing

Typical Applications

The filter press is widely used in various industries for sludge dewatering and solid-liquid separation. It is especially effective in treating high-moisture or high-viscosity sludge.

The filter press is often used in the following sectors:

Beverage processing

Dairy industry

Meat Processing

Mining industry

Municipal Wasterwater

Paint factory

Paper Mill

Petrochemicals

Printing and Dyeing

Sewage Treatment
