First stage pre-treatment(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.

Second stage pre-treatment (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.

Third stage pre-treatment (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.

RO system

Reverse osmosis membrane was only 0.001 micron pore size, can be harmful to remove dissolved solids and bacteria, 

viruses, etc., desalination rate of more than 99.6 percent, the host section contains the security filter, high-pressure pump 

and reverse osmosis membrane, security filters for the fourth grade and above pre-treatment systems, high-pressure pump 

is the host of one of the core equipment for the reverse osmosis membrane elements to provide sufficient pressure to 

overcome the penetration resistance to pressure and run to meet the needs of a device to achieve the rated water.

Product scope

It is mainly composed of the following equipments:pre-treatment system (water tank,multi-medium filter, active carbon filter, ion exchanger, millipore filter), membrane separation system (ultra filter, nanometer filter, RO system), electrodialysis device, sterilization system (UV device, ozone device) ,product water tank and some other machines.

 1. produce the water treatment system according to customer’s raw water quality report or customer requirement with World health organization living instant-drinking water standard.

 2. All the valves, pipeline will be with stainless steel SUS304 or SUS316L, with compact structure.

 3. All the machine will be PLC controlled, can be operated automatically, and also have installed with conductivity meter monitor, pressure gauge and flow meter. All the parameter in the machine can be monitored easily.

 4. With the high pressure pump, the raw water will be pumped into the quartz sand filter, passing through the quartz sand in the filter, any particle more than 20 um will be filtered, such as sediment, manganese, rust, colloid material, mechanical impurities, suspended solid,etc.

 5. And then the water will pass through the active carbon filter, which will adsorb the smell and chemical residualin the water;

 6. With the third step of sodium filter, the heavy metal content in the water will be reduced, which will result the water more health for drinking; 

 7. With the above three pre-treatment, the water is more clean than used to.

 But still not arrive the best condition. During the whole process, one of the major process is reverse osmosis with special membrane, to protect the membrane in the reverse osmosis more better, we have to add the precise filter, which is used for cleaning the final big volume substance in water.

 8. After the above 4 treatment, the water will be pumped into reverse osmosis device, and then about 70% of the raw water will come to be pure water, others will be waste water and then drain out of the water treatment system.

 9.The membrane in the reverse osmosis device will be with 0.001 micron pore size, after this process, 99.2% of the heavy metal ion, cancerogen, etc in water will be absolutely removed.
