1. Original water storage tank (optional)

Store source water to deposit large and fine sand particles as well as chemical substances that can be deposited in the water. At the same time, cache the impact of unstable pressure in the original water pipe on the sewage treatment system. (such as pressure sensing caused by low or high pressure).

2. Original centrifugal water pump

Stable system power supply working pressure and stable water flow.

3. Multi substance filtration device

The key purpose of selecting a filtration device with multiple filter layers is to remove fine sand, rust, colloidal solution chemicals, suspended solids and other particles above 20um in the raw water. A series of practical operations such as backwashing and positive flushing can be carried out using manual valve operation or automatic control board. Ensure the water production quality of the equipment and increase its service life.

4. Activated carbon filter

The system adopts a coconut shell activated carbon filtration device, which can not only adsorb positive ions in electrolyte solutions, but also carry out ion exchange adsorption. Activated carbon adsorption can also reduce the oxygen consumption (COD) of potassium permanganate solution from 15mg/L (O2) to 2-7mg/L (O2). In addition, due to the adsorption effect, the concentration of adsorbed copies on the surface is increased. Therefore, it also has catalytic reactions, removes melanin, odors, many biochemical organic compounds in water, reduces the permanganate index of water, fertilizer pollutants, and removes trihalogenated (THM) and other pollutants in water. Manual valve operation or automatic control board can be used to carry out a series of practical operations such as backwashing and forward flushing. Ensure the water production quality of the equipment and increase its service life. At the same time, the equipment has its own maintenance and upkeep system, and the operating cost is very low.

5. Positive ion softening system/dosing system

In order to better dissolve the concentration and discharge of solid substances and facilitate the use of water, R/O equipment should avoid the occurrence of CaCO3, MgCO3, MgSO4, CaSO4, BaSO4, SrSO4, and SiSO4 concentration values on the concentrated water side, especially on the membrane component behind the RO equipment. If the concentration product exceeds its equilibrium solubility parameter, crystals will precipitate and damage the original membrane. Before entering the reverse osmosis membrane component, positive ion softening equipment or appropriate reverse osmosis scale inhibitors should be applied to block the crystallization of sulfides, SiO2, and potassium thiocyanate for precipitation

6. Reverse osmosis equipment

Select reverse osmosis equipment to remove residual suspended solids, non straight particulate matter, colloidal solutions and other chemical substances in the influent water, so that the RO system can be stabilized

Continuous equipment operation is safer and more reliable. The filter element is a 5um melt blown filter element, and the purpose is to avoid the higher-level filtering module first, and to remove residue exceeding 5um that jumps out. Avoid entering the reverse osmosis equipment to damage the surface of the membrane, thereby damaging the desalination characteristics of the membrane.

7. Reverse osmosis system

Reverse osmosis equipment uses sufficient working pressure to extract organic solvents (usually water) from aqueous solutions through reverse osmosis membranes (or semi permeable membranes). As this entire process and the direction of natural infiltration are reversed, it is called reverse osmosis.

The reverse osmosis method can be integrated into various saline source water, especially in high salinity water treatment technologies, which can achieve very good technical and economic benefits. The desalination rate of reverse osmosis method is improved, with high utilization rate, stable operation, small footprint, and simple practical operation. At the same time of desalination, reverse osmosis equipment also removes the vast majority of bacteria, colloidal solutions, and organic compounds with high relative molecular weight.

8. Ozone sterilizer

Eliminating bacteria caused by secondary pollution completely ensures the food hygiene standards of finished water
