Reverse osmosis water treatment technology is a relatively popular water treatment technology at present. With this technology, impurities in water can be effectively removed and high-quality, high-purity water can be obtained, which is more and more popular among people. The reverse osmosis device is the core equipment to realize the reverse osmosis technology, and its composition and structural principles are the key to realize its efficient and reliable operation.
(1) The pretreatment system generally includes raw water pump, quartz sand filter, activated carbon filter, softening and dosing device, precision security filter, etc. Its main function is to reduce the pollution index of raw water and other impurities such as residual chlorine, so as to meet the water inlet requirements of reverse osmosis. The equipment configuration of the pretreatment system should be determined according to the specific conditions of the raw water.
(2) The reverse osmosis system mainly includes multi-stage high-pressure pumps, reverse osmosis membrane elements, membrane shells (pressure vessels), supports, etc. Its main function is to further remove small impurities in the water, so that the quality of the effluent water can meet the requirements of use.
(3) The ultrapure water system is an additional configuration when the water quality of the reverse osmosis effluent cannot meet the quality of the water used. It mainly includes one or more equipments such as EDI and mixed bed. The ultrapure water system is based on reverse osmosis to further remove ions to meet the requirements of use.
(4) The electrical control system is used to control the normal operation of the entire reverse osmosis system. Including instruments, control panels, various electrical protection, electrical control cabinets, etc.
