diatomaceous filter

Working Principle

Diatomaceous earth is a natural powder composed of the shells of microscopic organisms called diatoms. It has a porous structure and a large specific surface area. When the liquid to be filtered passes through the diatomaceous earth layer, impurities and suspended solids are blocked by the pores of the diatomaceous earth, while the clean liquid passes through the gaps to achieve the purpose of filtration.

Types

• Plate - and - frame diatomaceous earth filter: It is composed of several filter units, each of which includes filter plates, filter frames, and filter paper. Before filtering, a pre - coating is formed by circulating a mixture containing diatomaceous earth to evenly adsorb diatomaceous earth on the surface of the filter paper.

• Candle - type diatomaceous earth filter: It is mainly composed of many vertical candle - shaped filter elements. It is fully automatically controlled by imported pneumatic valves and is联动controlled by Siemens PLC and a color touch screen.

• Horizontal disc - type diatomaceous earth filter: It uses a disc as a filter element. When the liquid to be filtered flows through the pre - coated diatomaceous earth layer, impurities are blocked, and the clean liquid passes through the gaps of the filter layer.

Application Fields

• Water treatment: It can be used for the treatment of drinking water, industrial water, etc., effectively removing suspended solids, colloids, and some microorganisms in water.

• Beverage production: In the production of beer, wine, fruit juice, and other beverages, it is used to filter out impurities, improve the clarity of beverages, and extend the shelf - life.

• Food industry: It is used in the filtration of edible oil, syrup, and other products to remove impurities and improve product quality.

Advantages

• It has high filtration accuracy and can effectively remove fine particles and impurities.

• The filtration speed is relatively fast, which can meet the requirements of large - scale production.

• The diatomaceous earth filter medium is relatively inexpensive and has a low cost of use.
