The principle of reverse osmosis purified water equipment is that when two solutions containing different concentrations of roots are separated by a semi permeable membrane, the solvent on the lower concentration side will spontaneously flow to the higher concentration side. This process is called infiltration. In general, the higher the concentration of the root system, the higher the osmotic pressure. On the contrary, if pressure is applied to the concentrated solution side and exceeds the osmotic pressure, the solvent on the concentrated side will permeate to the fresh water side at that pressure. This type of infiltration is called reverse osmosis because it is opposite to natural infiltration.

The production capacity of reverse osmosis purified water equipment is between 0.5m3/h and 1000m3/h, and the material of reverse osmosis pressure vessels is stainless steel or fiberglass. The reverse osmosis membrane adopts a low-pressure composite membrane. The desalination rate reaches 99%, and the operating pressure is 1.3-2.0 MPa based on water temperature and quality.

Equipment performance

Low pressure switch protects the high-pressure pump from damage due to water supply interruption

High efficiency and low noise high-pressure pumps reduce operating noise and energy consumption.

The use of a spiral composite membrane with high desalination rate and low operating pressure has changed the water quality, reduced operating costs, and resulted in a long service life.

Gas field water and concentrated water are respectively equipped with flow meters to monitor and adjust the production volume and system recovery rate.

Conductivity meter continuously monitors the water quality of produced water

The inlet and outlet pressure gauges continuously monitor the pressure difference of the reverse osmosis membrane, and prompt in a timely manner when cleaning is required

Automatic water shut-off valve to prevent water from entering during shutdown

Quickly flush the valve, regularly flush the membrane surface, and reduce contamination rate
