The “Sand Filter, Carbon Filter, Belt Softener, Fully Automatic Reverse Osmosis Water Purification System” is a common water treatment combination, mainly used to purify raw water and remove various impurities to obtain high – quality water. The following is an introduction to each component:
- Sand Filter: Also known as a quartz sand filter, it usually has an automatic back – washing and forward – washing function. The filter tank is usually made of FRP (fiber – reinforced plastic), and is filled with refined quartz sand. Its main function is to remove particulate matter such as rust, sediment, and suspended solids in water, reducing the SDI (Silt Density Index) value of the influent water, and playing a role in preliminary filtration of raw water.
- Carbon Filter: It is an adsorption filtration equipment with activated carbon as the filter material. The tank is made of stainless steel, carbon – steel rubber – lined or FRP. Activated carbon has a well – developed pore structure and a large specific surface area, which can adsorb organic matter, pigments, odors, residual chlorine and other substances in water through physical adsorption, chemical adsorption and filtration interception. There are various types of activated carbon, such as granular activated carbon, powdered activated carbon, and formed activated carbon.
- Belt Softener: Usually refers to a water softener, which has functions such as automatic operation, back – washing, salt absorption, and salt tank water replenishment. The filter tank is made of FRP, and is filled with renewable cation exchange resin. Cation exchange resin has a strong adsorption capacity for metal ions such as calcium carbonate, magnesium carbonate, calcium sulfate, and magnesium sulfate in water, which can reduce the hardness of water and prevent scale formation.
- Fully Automatic Reverse Osmosis Water Purification System: It is a water purification equipment that uses the pressure difference of a semi – permeable membrane to purify water. The reverse osmosis membrane can effectively remove most of the organic matter, harmful substances, bacteria, particulates, etc. in the raw water. The system usually includes components such as a high – pressure pump, a reverse osmosis membrane element, and a control system. The raw water is pretreated by a sand filter, carbon filter, softener, etc., and then enters the reverse osmosis membrane under pressure. The pure water produced can meet high – quality water standards and is widely used in various fields such as tap water, well water, and underground water purification, as well as pure water and ultra – pure water production.
