1、Raw water tank (optional).

Storage of raw water, used to precipitate large sediment particles and other precipitable materials in the water. At the same time buffer the original water pipe in the water pressure instability caused by the impact of the water treatment system. (Such as water pressure is too low or too high caused by the reaction of the pressure sensing).

2、Original water pump.

Constant system water pressure, stable water supply.

3、Multi-media filter.

The use of multiple filter layers of the filter, the main purpose is to remove the raw water contains sediment, rust, colloidal substances, suspended matter and other particles in more than 20um, can be selected for manual valve control or fully automatic controller for backwashing, positive flushing and a series of operations. Ensure the quality of the water produced by the equipment and extend the service life of the equipment.

4、Activated carbon filter.

The system adopts activated carbon filter with fruit shell, which can not only adsorb electrolyte ions, but also carry out ion exchange adsorption. The adsorption of activated carbon can also reduce the oxygen consumption of potassium permanganate (COD) from 15mg/L (O2) to 2~7mg/L (O2), in addition, the adsorption effect increases the concentration of the adsorbed copy on the surface, so it also plays a catalytic role, removes the pigment, odor, a large number of biochemical organic substances in the water, reduces the residual chlorine value of water and pesticide pollutants and removes the trihalide (THM) and other pollutants in the water. and other contaminants. Manual valve control or fully automatic controller can be used for a series of operations such as backwashing and forward flushing. This ensures the quality of the water produced and extends the service life of the equipment. At the same time, the equipment has a self-maintenance system, the operating costs are very low

5、Ion softening system / dosing system.

R / O device in order to dissolve the solids of the concentrated discharge and the use of fresh water, in order to prevent the concentration of CaCO3, MgCO3, MgSO4, CaSO4, BaSO4, SrSO4, SiSO4 concentration product is greater than its equilibrium solubility constant and crystallization precipitation, damage to the membrane original characteristics, in the last membrane component of the RO device, especially the concentrated water side, into the reverse osmosis membrane Before entering into the reverse osmosis membrane, ion softening device or appropriate amount of scale inhibitor should be used to stop the precipitation of carbonate, SiO2, sulfate crystals.

6、Precision filter.

The use of precision filter to remove the residual suspended matter, non-curved particles and colloids in the feed water, so that the RO system and other subsequent equipment operation is safer and more reliable. The cartridge is 5um meltblown cartridge, the purpose of the upper filter unit to prevent the removal of impurities greater than 5um missed. Prevent the surface of the membrane from being damaged by entering the reverse osmosis unit, thus damaging the desalination performance of the membrane.

7、Reverse osmosis system.

Reverse osmosis unit is used with sufficient pressure to make the solvent in the solution (generally water) through the reverse osmosis membrane (or semi-permeable membrane) and separated out, because the process and natural osmosis in the opposite direction, so called reverse osmosis. Reverse osmosis method can adapt to all kinds of raw water with salinity, especially in water treatment projects with high salinity, and can obtain very good technical and economic benefits. Reverse osmosis method has improved desalination rate, high recovery rate, stable operation, small footprint and easy operation. Reverse osmosis equipment also removes most bacteria, colloids and large molecular weight organic matter while removing salt
