Introduction to Mechanical Filters

Mechanical filters are generally used in the pretreatment process of water treatment projects, mainly to remove mechanical impurities, colloids, microorganisms, organic matter and active chlorine. Shell materials generally include PE, steel lining, steel spray and steel epoxy anti-corrosion, stainless steel and glass fiber reinforced plastic. According to different process needs, the filter media generally include quartz sand, activated carbon, manganese sand, anthracite and so on. According to the water inlet method, it can be divided into single-flow filter and double-flow filter, which can be used in combination or alone according to the actual situation.Compressor impeller vacuum heat treatment The single-flow mechanical filter has simple piping and smooth operation. The filtration flow rate is generally 4-50m/h, and the operation period is generally 8 hours. The upper and lower ends of the double-flow mechanical filter are provided with water inlet devices, and the middle part is provided with a water outlet device. The advantages are that the amount of filtered water is large, the decontamination ability is high, and the operation period is long, generally 20 hours.Aluminum alloy micro-channel cooling plate vacuum gas quenching Mechanical filtration is widely used in the water treatment process, mainly used for water treatment to remove turbidity, reverse osmosis, and the pre-treatment of ion exchange softening and desalination systems, and can also be used for surface water and groundwater to remove sediment. The inlet water turbidity is required to be less than 20 degrees, and the effluent turbidity can reach below 3 degrees. The double-layer filter material is: the upper layer of anthracite is 400mm/1.2～2.5mm; the lower layer of quartz sand is 800mm/0.5～1.2mm.Aluminum alloy finned radiator vacuum brazing
