A complete reverse osmosis purified water equipment system consists of a pretreatment section, a reverse osmosis host (membrane filtration section), a post-treatment section, and a system cleaning section. 2.Pre treatment section of reverse osmosis purified water equipment The pretreatment of reverse osmosis purified water equipment often consists of quartz sand filtration device, activated carbon filtration device, and precision filtration device. The main purpose is to remove sediment, rust, colloidal substances, suspended solids, pigments, odors, biochemical organic compounds, and reduce harmful substances such as residual ammonia value and pesticide pollution in the raw water. If the content of calcium and magnesium ions in the raw water is high, it is necessary to add a soft water device, mainly to protect the reverse osmosis membrane in the later stage from damage by large particles, thereby extending the service life of the reverse osmosis membrane. 3.Reverse osmosis purified water equipment host Mainly composed of booster pump, membrane shell, reverse osmosis membrane, control circuit, etc., it is the core part of the entire water treatment system, and the quality of the produced water also depends on this part. As long as the membrane model and booster pump model are selected properly, the reverse osmosis host can achieve a filtration capacity of over 99% for salt in water, and the effluent conductivity can be guaranteed to be within 10us/cm (25 degrees).
