The types of filters include liquid filters, air filters, high efficiency filters, etc. As an indispensable part of modern industry and daily life, filters have a wide variety of functions and are widely used in many fields. The following is a detailed description of the filter types:
1. Liquid filter
Liquid filters are mainly used to separate suspended solids, particles and chemicals in liquids. Common liquid filters include precision filters, bag filters, and activated carbon filters. Precision filters are used to remove very small particles in water, and are often used in the food and beverage industry and the electronics industry. Bag filter is mostly used for industrial sewage treatment, which can filter out fine solid suspended matter; Activated carbon filters are mainly used to adsorb organic matter and pigment in water, and are often used to purify drinking water.
2. Air filter
Air filters are mainly used to remove dust particles and other pollutants from the air. According to filtration efficiency, air filters are divided into primary filter, medium filter, high efficiency filter and ultra-high efficiency filter.
3. High efficiency filter
High efficiency filter is a kind of equipment used to capture particles of dust below 0.5um and a variety of suspended matter, mainly used in optical electronics, biomedicine, beverage and food industries clean workshop and clean workshop. The efficiency and performance of high efficiency filters are high, which can effectively reduce pollutants in the air and protect the environment and human health.
4. Automatic filter
Automatic filters are usually equipped with differential pressure controllers and timing controllers, which can realize automatic cleaning and blowdown, and are widely used in agricultural irrigation, industrial circulating water systems and urban water supply fields. Its advantage is that it has a high degree of automation, which can reduce manual operation and improve filtration efficiency.
5. Special function filter
Special functional filters include softened water filters (to reduce the hardness of water), quartz sand filters (for primary filtration in water treatment systems), manganese sand filters (to remove iron and manganese ions from water), and so on. These filters provide effective solutions for specific water quality problems and are used in specific industrial and agricultural sectors.
