The reverse osmosis(RO) water treatment plant is an equipment to purify water with the action of pressure difference of semi permeable membrane. RO membranes can effectively remove majority of organics, harmful substances, bacteria, particulates etc in the raw water. RO system is widely used in water treatment, purification for tap water, well water, underground water, borehole salty water, brackish water and seawater, pure water and ultra-pure water production, power stations, electronic industries, cosmetics production, medicine(pharmaceuticals) manufactories, and medical treatment(such as hemodialysis). It is a key equipment for pure water plant and ultrapure water equipment.
This water treatment system is suitable for purifying borehole salty water, normal municipal tap water, underground water, lake water, river water, requires water source TDS (Total Dissolved Solids) less than 2000mg/L. If your source water is very salty water, please send email and inform us about the features of the water, it will be better if you have water quality analysis report. Thank you for clicking our products in more than ten thousands of products.

S/N. | Commodity name | Application | Remark |
1 | Raw water tank | Store water, buffering pressure, overcome instability of supplying water by pipe, ensure to supply water stably and continuously for whole system | Customers provide for themselves, because big size will result in expensive freight. |
2 | Raw water pump or called booster pump | Provides needed pressure for every pretreatment filter | We can provide CNP pumps or Grundfos pumps |
3 | Mechanical filter or called quartz sand filter or sand filter | We use fiber glass or stainless steel vessel as housing, fill quarts sand, it can filter big particles impurities, suspended substances, colloids etc. | |
4 | Activated carbon filter | We use fiber glass or stainless steel vessel as housing, fill activated carbon, remove color, odor, residual chlorine and organics substances. | |
5 | Water softener, demineralizer, or called Na+ exchanger | Adopt cation resin to soften water, cation resin will absorb Ca2+, Mg2+(main elements for composing scale), reduce hardness of raw water, System can make resin intelligently regenerate, recycling | Optional, when total hardness is between 100ppm to 500ppm, have to use water softener. |
6 | Security filter or pp filter, or called PP sediment filter | prevent large particles, bacteria, viruses into RO membrane, accuracy is 5µm, | |
7 | High pressure pump | Provide needed working pressure for RO system, ensure production capacity of pure water. | CNP pump, Grundfos optional |
8 | RO(reverse osmosis) system | Can remove particles, colloids, organic impurities, heavy metal ions, bacteria, virus, heat source etc. harmful substances and 99% dissolved salts. | RO membranes USA Filmtec Dow |
9 | UV sterilizer or Ozone generator | Kill 99.99% bacteria, virus etc. |

We can't give you very low price, can only give you very good quality. We would rather explain for the price for a while, are not willing to apologize for the quality problem during machine's lifetime, we think only if we have good quality and after-sale service, it is what we are proud of. For promise, we will not betray the future for short-term profits, in order to get the customer's approval and follow, we work hard and insist!

Our engineers can go abroad for installing the water filtration systems, but clients must bear the round air tickets and visa application, food, accommodation etc.We will teach workers how to operate step by step. Installation details will be illustrated in sales contract. For small production capacity, clinets will know how to operate as our English manual book, operation video etc.
