II..Description
Water feeding pump
Requested access to the system's raw water has a stable flow and pressure, its purpose is to prevent water fluctuations have an impact on the system operation to ensure the stability of the system into the water. After the original pumps pressurized raw water sent to the system.
 
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.
 The main structure: barrel body, baffles, manhole, gauge, filter head, filter, into the water pipes, drains and flushing water mains, as well as access to water, such as the composition of backwashing valve.
Media placement: the placement of single-layer media, there are 0.5 --- 0.53mm particle size of quartz sand composition, thickness 600-700mm, the normal flow rate of particle size 0.5 --- 0.6mm ,10-15M / H, particle size 0.5 --- 1.2mm, 8-10M / H .
 Backwashing strength as the 10-15L / (m * S), expansion rate of 50%, washing lasted 10 min. Working pressure : 0.2 --- 0 .6 Mpa, temperature :5 - 60 ºC.
 
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.
 Pure water in the manufacturing process, activated carbon adsorption performance in four areas: reducing the oxidation of water requirements; to avoid entering the organic matter, pollution ion-exchange membrane and reverse osmosis membrane; reduce the residual chlorine in the water to protect the reverse osmosis membrane; remove water three halides, such as to improve the overall quality of water.
 The main structure: barrel body, baffles, manhole, gauge, filter head, filter, into the water pipes, drains and flushing water mains, as well as access to water, such as the composition of backwashing valve.
 Media placement: the placement of single-layer media, 0.2 --- 0.3m loaded at the bottom of the quartz sand filter layer of quartz sand in the upper 1-1.5m thick loaded activated carbon, and adsorption filters, flow rate is 6 -- 10M / H, when the non-quartz sand filter, the flow rate of 3-10M / H, backwashing strength of 4-12L (S * m). Working pressure: 0.2 --- 0 .6 Mpa, temperature :5 - 60 ºC.
 
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.
 The main structure: barrel body, baffles, manhole, gauge, filter head, filter, into the water pipes, drains and flushing water mains, as well as access to water, such as the composition of backwashing valve.
 Flow rate of the general operation of 15-20M / H, water hardness of 0.03mmol / L the following.
 The purpose of washing is to remove the anti-lipid layer of pressure to loose dirt Panniculitis pressure, clear liquid pipe filter, flow rate 5-10M / H, time 10-15 minutes
 Ion regeneration: exclusion of water, into the regeneration fluid, cleaning replacement. Renewable liquid salt concentration of 3% - 5%, regenerant consumption 80-100g/mol, resin layer does not flow to the disturbance as the standard, the water hardness is less than 0.5Meq / L.
 Wash flow rate is 10-15M / H, 2-10Min.
 Working pressure: 0.2 --- 0 .6 Mpa, temperature: 5 - 60 ºC.
 
Fourth stage pretreatment (Micron filter)
Particle size in water to remove fine particles, sand filters can remove very small colloidal particles in the water, so that the turbidity reached 1 degree, but still per milliliter of water for hundreds of thousands of particle size 1-5 microns colloidal particles, the pressure on this filter to remove water after the particle size of 100 microns or less in small particles, to further reduce the turbidity, to meet the next process of the water requirements of the protection of the next long-running processes.
 
UV sterilizer
ZX series ultraviolet sterilizer is device for small-scale water disinfection. It can cooperate with soft drink packaging machine, and disinfect quickly and efficiently without changing the physical and chemical quality of water. It has no harmful metal ion to pollute the environment and no halogenide. The water disinfected by it can reach the standard of drinking water. It consists of ultraviolet, quartz glass tube, stainless steel tube, electric controller, etc. To bear inner-pressure sealed tin.
