Mechanical filters are also called pressure filters. It is an important part of the pre-treatment and water purification system for pure water preparation. The material is made of steel rubber lined or stainless steel. According to the different filter media, it is divided into natural quartz sand filter, multi-media filter, activated carbon filter, manganese sand filter, etc. According to the water inlet method, it can be divided into single-flow filter, The dual-flow filter can be used in combination or alone according to the actual situation.
Mechanical filter is to use one or several filter media, under a certain pressure, make the original liquid pass through the media to remove impurities, so as to achieve the purpose of filtration. The fillers inside are generally: quartz sand, anthracite, granular porous ceramics, manganese sand, etc. The user can choose to use according to the actual situation.
Mechanical filter mainly uses fillers to reduce water turbidity, intercepts suspended solids, organic matter, colloidal particles, microorganisms, chlorine smell and some heavy metal ions in the water in the area, and is one of the traditional water treatment methods to purify the feed water.
Mechanical filtration is widely used in the water treatment process, mainly used for water treatment to remove turbidity, reverse osmosis, and the pre-pretreatment of ion exchange softening and desalination systems. It can also be used for surface water and groundwater removal. The inlet water turbidity is required to be less than 20 degrees, and the effluent turbidity can reach 3 degrees or less.
The size of the mechanical filter depends on the amount of water. A3 steel, stainless steel or glass fiber reinforced plastic can be selected according to different uses. According to the water quality and the requirements of the water quality, you can choose single-layer filter material, double-layer filter material or multilayer Filter material.
