Principle of reverse osmosis membrane

Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane, and is the core component of reverse osmosis technology. The membrane pore size of reverse osmosis membrane is small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation.

What are the characteristics of reverse osmosis?

It should have high desalination rate at high flow rate, high mechanical strength and service life, can function at low operating pressure, can withstand the influence of chemical or biological effects, and is less affected by factors such as pH value and temperature. The raw materials for molding are easy to source, simple to process and low in cost.

Selection of reverse osmosis membrane

Customers often ask what performance indicators we need to consider when choosing a reverse osmosis membrane. Usually divided into three: desalination rate, water production, and recovery rate.

Process flow

Raw water → raw water tank → raw water pump → multi-media filter (quartz sand filter) - activated carbon filter → soft water processor (antiscalant adding device) → precision filter -> high pressure pump → first-stage reverse osmosis (RO) device → ultraviolet disinfection device (ozone disinfection device) → water use point.
