Product Description:


1.  The reverse osmosis device is an equipment to purify the saline water with the action of pressure difference of semi permeable membrane,it is called reverse osmosis,as it is counter to natural penetration direction,


Different materials have different osmotic pressures,The reverse osmosis method to adopt larger osmotic pressures is used to obtain the purpose to separate,extract,purify and condense.



1.quartz sand filter

Raw water into the filter for a simple mechanical filter, mainly to remove suspended solids in water, colloidal particles and other large impurities in the water when the water pressure and the pressure difference over 10Psi (0.7kg/cm2) or water SDI> 5, the need for backwashing . In general, before running back wash once a day.


2. activated carbon filter

Activated carbon is used wood, coal, shell (nuclear) and other carbonaceous material through chemical or physical method activation made. It has a very large number of pores and specific surface area, which has a strong physical adsorption capacity, the effective adsorption of organic pollutants in water. Primarily to remove organic matter in raw water, chlorine, odor, color, etc., so that the original residual chlorine in water ≤ 0.1mg / l, effective protection of RO membrane from chlorine damage to parts of activated carbon typically 12 to 18 months to replace a The main residual chlorine as determined in raw water.

Under normal circumstances, it needs to backwash once a week.

3.  Precise filter

The third pretreatment, filter spray for the polypropylene melt, filter housing is ABS material, mainly to remove the vast majority of very fine suspended solids.

4.  Reverse osmosis plant

RO reverse osmosis equipment adopts the membrane separation to remove the water ions, organic matter, colloidal particles, bacteria and other impurities in the water desalination and purification to achieve the purpose. The principle is the solution to penetrate the membrane of water and separated, the water is leaking to the solution, the osmotic pressure between the two phases, if the solution phase on the pressure, so the pressure is the osmotic pressure, the solution to the water, the water will be the opposite infiltration to, obtained using reverse osmosis desalination of water. That is enough pressure in the raw water, through the permeable membrane and into pure water, no water through the membrane, the dissolved, suspended solids concentration increases gradually, as the concentration of water out.

Reverse osmosis plant can not only desalt, but also filter out the organic matter, bacteria and so on.  

5. This equipment uses mechanical filters, activated carbon filter as a pre-treatment, it is useful to remove the suspended solids in raw water, sediment particles, organic colloids, organic matter, odor, chlorine and other impurities. With control programmed device as a pre-desalination plant to remove most of the dissolved salts, bacteria, hot stream and so on in raw water, and then using the Ozone device to guarantee the finished water quality standards.

The system is set up automatic and manual modes. Custom programmed system uses conventional relay as the central control device, through the multi-point multi-way  level sensor, dynamic pressure controller combinations to achieve the automatic mode. Manual mode can be used to installation and maintenance the failure which the automatic mode can not work.

 Under normal circumstances, the system can be placed in automatic operation mode of the work of continuous operation, it will automaticly monitor water quality, operation simple, stable, safe and reliable.
