A membrane that is selective for what is permeated becomes a semipermeable membrane. Generally, a membrane that can only permeate a solvent but not a solute is regarded as an ideal semipermeable me...

1. Using reverse osmosis membrane (RO membrane), using the most advanced reverse osmosis technology in the world to prepare pure water; 2. Five-stage filtration, comprehensively play the effective ...

After the RO water treatment process separates the influent, it will inevitably produce concentrated water. The main feature of the concentrated water is that the salt content is relatively large. ...

Since the 1960s, RO desalination has become an important way to obtain drinking water and an effective method to solve the shortage of fresh water resources. RO desalination technology is mainly us...

Compared with other traditional separation engineering, RO separation process has its unique advantages: (1) Pressure is the main driving force in the RO separation process, without the phase trans...

The development of RO membranes has roughly gone through three stages. The commonly used RO membrane materials in my country mainly include cellulose acetate membrane (CA membrane), aromatic polyam...

The RO membrane itself is sensitive to the pH, temperature and specific chemical substances of the influent water. The water quality of the influent water strictly requires a pH value range of 4~10...

RO (Reverse Osmosis) is a membrane process that uses the selectivity of the RO membrane and uses the static pressure difference on both sides of the membrane as the driving force to overcome the os...

RO water treatment system, also known as reverse osmosis water treatment system, is a membrane separation technology developed in the 1960s. The principle is that the raw water passes through the r...

The principle of RO water purification is also known as the principle of RO reverse osmosis. RO reverse osmosis is a method of filtering the raw water (physical method) through internationally popu...

There are several classic models for the unified "dry closed wet open" reverse osmosis mechanism model 1. Preferential adsorption capillary pore model: no pores were found under the weak ...

In 1950, DR.S.Sourirajan, an American scientist, accidentally discovered that seagulls sipped a large mouthful of seawater from the sea surface while flying at sea. It is absolutely impossible to d...
