Filter Press - Batch Pressure Filter with Fixed Volume

What is filter press?
Filter press is a machine for solid/liquid separation by forcing the feed slurry through a permeable filter cloth. The separation process takes place in chambers formed between every two filter plates. In this case, the solid phase is inside the chambers (forming a so-called "cake"), and the liquid phase (filtrate) penetrates through the filter media and flows out through the discharge ports.

Main components of a filter press
A filter press has two main components: the framework and the filter pack. The framework holds the filter pack together while pressure is being developed inside the filtration chamber. The chamber however can only hold a specific volume of solids. And the major difference in the type of filter press is the style of plates used in the filter pack.

The filter press is mainly used as a batch pressure filter with fixed volumes. In this case, the machine is designed to process a specific quantity of solids per filtration cycle for efficiency work, if not filled to capacity with solids, the filter cake will not reach its maximum potential for cake dryness. The "batch" means that it is necessary to interrupt the cycle to discharge the collected solids (filter cakes) before starting a new cycle. Its operating cycle of the filter press includes the following steps:

• Closing the filter press.
• Filling in slurry.
• Dewatering.
• Filter opening.
• Washing.

Where can filter press be used?

Filter presses are used in a huge variety of different applications. In our everyday life, we get in contact with many products, where a filter press is involved in the production process. Ultimately the treatment of waste water sludge and drinking water is typical application of filter press. Other applications like production of food and beverages, mining industry, and development of chemicals require filters that separate solids from liquids.

• For better realizing an effective dewatering, we provide our customers with broad experience to deliver a customized solution.
• It is crucial to guarantee safety in food industry for food consumers and producers. Boegger filter press ensures this expectation and contributes to sophisticated design for conforming to highest hygienic standards.
• With corrosion protection and an innovative control of process parameters such as flow rates, pressures, our filter press ensures economically optimized solution to efficiency separation in chemicals.
• Filter presses are commonly used from bulk mining to metallurgy processing, where dewatering has been an increasingly important process. We secure optimum product quality in applications such as coal, tailings, concentrates, rare earth, kaolin, bauxite, etc.

Water & Waste water

Suspended solids exist in nearly every municipal or industrial waste water treatment process. Boegger filter press provides the biggest advantage of minimum energy costs and maximum dry solid content in the filter cake.

Food

By innovative process control, we provide an effective and economic food processing solution. Exemplary applications in food industry include cooking oil, beer, wine, juice, coffee, syrup, flavouring agents, yeast.

Chemicals

Dewatering step is necessary in the diverse chemical and biochemical processes or for the final products. Membrane filter press is ideal for the processing of pigments, bioplastics, catalyst, petrochemicals, etc.

Mining & Metallurgy

Benefits of dry tailings disposal become increasingly appreciated from both environmental and social responsibility perspectives. In metallurgical or mining process, efficient filter cake washing can be realized by filter press.
