Chamber filter press

Chamber Filter Press – High-Efficiency Filtration Solution

A chamber filter press is a widely used filtration device in various industries for solid-liquid separation. It is particularly popular in wastewater treatment plants, mining operations, chemical industries, and food processing plants. The device works by forcing the liquid portion to pass through the filter cloth while retaining the solid particles within the chambers.

The basic structure of a chamber filter press consists of a series of filter plates with filter cloths, arranged alternately with solid plates. Our product’s plates are typically made from materials such as polypropylene, cast iron, or stainless steel, depending on the application and the nature of the material being filtered. Each plate has a central cavity or chamber where the solids accumulate during the filtration process.

How to choose a suitable chamber filter press

1. Application areas: Filter presses are widely used in many industries such as food, beverage, chemical, pharmaceutical, environmental protection, etc. First determine your industry and specific application, which will affect the model and material selection of the filter press.
2. Filter chamber design: Chamber filter presses consist of filter plates and filter frames, with filter cloth between the filter plates to form a filter chamber. According to the characteristics of the filtered material, choose the appropriate filter plate material, such as polypropylene or other materials.
3. Filter plate size: The size of the filter plate affects the filtration area and filtration capacity. Common sizes are 470 x 470 mm, 630 x 630 mm, and 800 x 800 mm. Choose the filter plate size that suits your production needs.
4. Filter cake thickness: The filter cake thickness of different models of filter presses may be different, usually 30 mm. Choose the appropriate filter cake thickness according to the characteristics of the filtered material and the required filter cake thickness.
5. Filter press configuration: The filter press can be equipped with a diaphragm or chamber filter plate, which can be selected according to whether mechanical extrusion of the filter cake is required. Membrane filter plates can provide higher yields and drier filter cakes while shortening filtration cycles by approximately 50%.

Filtration Principle

The filter cloth acts as a medium that allows the liquid to pass through while retaining the solids. This results in the formation of filter cakes within the chambers and the collection of filtrate, enabling effective solid-liquid separation.

1. Filtration: The chamber filter press applies pressure to the slurry by either hydraulic or mechanical means. This pressure forces the liquid portion of the slurry to pass through the filter cloth while retaining the solid particles within the chambers.
2. Cake Formation: As the liquid passes through the filter cloth, a layer of solid particles, known as the filter cake, forms on the surface of the cloth within each chamber.
3. Filtrate Collection: The liquid portion of the slurry, called the filtrate, passes through the filter cloth and is collected in a drainage system or collection channel.
4. Cloth Cleaning: Over time, the filter cloths may become clogged with accumulated solids, reducing filtration efficiency. Periodic cleaning or replacement of the filter cloths is necessary to maintain the performance of the chamber filter press.

Applications of Chamber Filter Press

1. Wastewater Treatment: Chamber filter presses are widely used in municipal and industrial wastewater treatment plants. This application helps in reducing the volume of sludge for disposal and achieving cleaner water.
2. Mining and Minerals: In the mining industry, chamber filter presses are used for dewatering mining slurries and recovering valuable minerals. They can separate solids from mining tailings, concentrate slurries, and other mining process streams. By removing water from the slurry, chamber filter presses facilitate the handling and disposal of solid waste and enable the recovery of water and valuable minerals.
3. Chemical Industry: Chamber filter presses help improve product quality, reduce waste, and enhance process efficiency in chemical manufacturing.
4. Food and Beverage: The food and beverage industry utilizes chamber filter presses for various applications. These presses help remove solids, particles, and impurities, ensuring product clarity and quality.
