Filtering is the method with commonly used water treatment equipment, filtration equipment, also known as filters, he includes quartz sand filter, activated carbon filter, many medium filter, manganese sand filter, bag filter, precision filter, etc. , all the water purification filter is mainly used to remove the suspended solids in the water, organic matter, colour, taste, overall mainly improve the sense of water, let the water clear, refreshing.
the following to introduce the role and function of various kinds of filter equipment. 1, quartz sand filter

quartz sand filter in general as a pure water equipment, and the pretreatment of the ultrafiltration device, he mainly through filter layer sediment, colloid, metal ions and organic matter to intercept, adsorption. Commonly used in water treatment, because of its no pollution, low prices, low running cost, so more widely.
2, activated carbon filter,
is a kind of very small granular activated carbon has a great deal of microporous per unit area, usually we call him capillary hole. The capillary has very strong adsorption capacity, due to the granular surface area is large, in contact with and impurities. These impurities can be adsorbed in the pores, to remove impurities such as the water gel. Activated carbon can adsorb the CL ion in the water and ozone, to the organic matter in the water also to have certain adsorption ability, can obviously on the pigment in the water adsorption, we ask that iodine value in the water treatment industry in more than 700 mg, such activated carbon adsorption ability is stronger.
3 and medium filter
medium filter as the name suggests is fill filter material have more than one and two or more of the mechanical filter called medium filter, used in water treatment filter medium, common medium filter filter material has: anthracite coal, clay, quartz sand, activated carbon, etc. Many medium filter filter size requirements in the design filter material generally lower filter material particle size, particle size is smaller than the upper filter in place to ensure that the lower the effectiveness of the filter material and make full use of. Upper density is smaller, in order to keep the layered recovery after backwashing, if the upper density is small, so the upper after backwashing filter material sink to the lower level. In the two layers of filter bed, for example, the upper filter material particles, the largest density of small light filter material, such as anthracite coal, activated carbon; The lower filter material particle size is small, dense, generally for quartz sand; Formed the upper plays a role of coarse filter filter material, resistance, head loss, lower function fine filtration filter material, cutting carrying capacity is strong, thus give full play to the multiple medium filter bed, the head loss, good filtering effect characteristics, fully delivery advantages of each layer.
4, iron manganese filters
iron and manganese removal filter is also known as manganese sand filter, rely mainly on its own the catalysis of manganese sand, and when the filter in manganese sand filter materials gradually formed on the surface of a layer of iron as an active filter membrane filtration membrane, can a catalytic role. New generation of iron oxide as a new catalytic active membrane filter material is involved in iron removal process, so the active membrane filter in addition to iron process is an autocatalytic process. Mainly used for processing of groundwater, water treatment level of sewage treatment, etc.
5, fiber ball filter
fiber ball filter, as the name suggests, is built in fiber ball filter, is also a kind of pressure type mechanical filter, fiber ball filter fiber ball porosity in the accounts for about 93% of the filter material layer. Fiber ball filter running water into the bottom go to, because the water flow through filter layer, the resistance of the filter material formed on panasonic tight space structure of the ideal, not only flux is big, also increased the section carrying capacity, he effectively remove the suspended solids in the water, sediment, and organic matter in water, colloid, iron, manganese, etc have obvious removing effect, the product is applied in the fields of oily wastewater and the fine filter, filtration flux and fiber ball not sticky oil, so widely used in petrochemical industry.
the above filters each filter packing is different, action principle is different, so the application is also different. And filters due to its different applications, different water quality, the material is different also, in general, on the market the most had 304 stainless steel, carbon steel, stainless steel 316 l, fiberglass filter material, etc.
