As a new type of purely physical desalination process, reverse osmosis equipment has high requirements for feed water due to the structure, material and desalination mechanism of the reverse osmosis membrane element and other conditions.Temperature conditions between 1 and 45°C;The pH value must be

Why pre-treatment is required before entering the reverse osmosis membraneAs a new type of pure physical desalination process, reverse osmosis equipment has high requirements for feed water due to the structure, material and desalination mechanism of the reverse osmosis membrane element.Learn more a

Thin-film composite membrane - A thin film composite or TFC is a reverse osmosis membrane composed of and manufactured as three layers bonded together.

1.Sediment filtration methodThe purpose of the sediment filtration method is to remove the suspended particulate matter or colloidal material from the raw water. These particulate matter, if not removed, will cause damage or blockage to other sophisticated filtration membrane. Commonly used in the i

What is heavy contamination of reverse osmosis membrane elements？

Desalination is a realistic requirement for coastal areas to break the bottleneck of fresh water resources shortage, guarantee the safety of urban water supply and optimise the quality of urban water supply. As we all know, the salt and impurity content in seawater is too high, far exceeding

Pure water equipment can be used in the chemical, pharmaceutical and food industries. There will be a full set of pretreatment devices in the whole system, mainly for the preliminary treatment of raw water to meet the feed water requirements of the reverse osmosis mainframe. The reason why the rever

Raw water contains a certain concentration of suspended and dissolved substances. Suspended matter is mainly inorganic salts, colloids and biological particles such as micro-organisms and algae. Dissolved substances are mainly soluble and insoluble salts (e.g. carbonates, sulphates and silicates

When reverse osmosis membrane elements are used, the RO feed water should be dechlorinated in order to prevent the membrane from being oxidized. RO membranes have a degree of resistance to chlorine until a significant drop in desalination occurs, which is approximately 200-1000 hours of exposure to

Every reverse osmosis system is subject to contamination and requires cleaning. Since contamination usually occurs with more than one type of contaminant, the typical cleaning process usually includes two major steps, low pH cleaning and high pH cleaning, as required.Different contaminants should be
