Typical process flow

Raw water Pump + Multi-Medium Filter (Quartz Sand Filter + Activated Carbon Filter + Chemical dosing device + Security Filter) + High pressure Pump + Reverse Osmosis Host (HYDRANAUTICS 4040/8040) + Middle Water Tank + Middle Delivery Pump +Mix Bed/EDI system + Water tank+ Ultraviolet/Ozone Generator + Pump  + Terminal Filter +Pure Water tank


1 First stage pretreatment (Sand filter)

The use of multi-medium quartz sand filters, main purpose is to remove the water contains sediment, manganese, rust, colloid material, mechanical impurities, suspended solids and other particles in the above 20UM of substances hazardous to health. The effluent turbidity is less than 0.5NTU, CODMN less than 1.5mg / L, iron content of less than 0.05mg / L, SDI less than or equal to 5. Water filter is a kind of "physical - chemical" process, the water through granular materials when isolated filter water impurities and colloidal suspensions. Filter is an effective water purification and treatment of the main process in the preparation of pure water is an indispensable process.


2 Second stage pretreatment (Carbon filter)

Activated carbon filters used to remove the pigment in the water, smell, a large number of chemical and biological organisms, reducing the residual value of water and pesticide pollution and other harmful pollutants. The structure of activated carbon filters and quartz sand filters, the difference is placed inside the strong adsorption capacity of activated carbon for removal by the quartz sand filter without the filter out organic material, adsorption of residual chlorine in the water, using water more than less than or equal to chlorine 0.1ML/M3, SDI less than or equal to 4, are strong oxidants chlorine, there are various types of membrane damage, in particular, reverse osmosis membranes are more sensitive to chlorine. In addition, the activation process, the surface of activated carbon to form non-crystalline parts of some oxygen-containing functional groups, these functional groups can have a chemical adsorption of activated carbon catalytic oxidation of bad news, to restore the performance, can effectively remove a number of metal ions in water.


3. Third stage pretreatment (Resin softener)

Cationic resin used for water softening, primarily to remove hardness of water. The hardness of water is a major calcium (Ca2 +), magnesium (Mg2 +) ion composition, when containing the raw water hardness ions through the resin layer, the water of the Ca2 +, Mg2 + was exchanged resin adsorption, and other objects at the same time the quality of the release of sodium Na + ions flow from the softener in the water is removed from the softened water hardness ions. So as to effectively prevent the reverse osmosis membrane fouling, system can automatically recoil, and so is red.
