How Does a Reverse Osmosis Membrane Work?
2026-07-01
Reverse osmosis (RO) is the world’s leading membrane technology for producing high-quality purified water. From drinking water systems and seawater desalination plants to pharmaceutical manufacturing and semiconductor production, reverse osmosis membranes play a vital role in removing disso... -
Why does the pH value of reverse osmosis permeate decrease?
2026-06-30
Under normal circumstances, a certain amount of carbon dioxide dissolves in water. After dissolving in water, carbon dioxide reacts with water to form a carbonic acid equilibrium, as shown in the following reaction equation: CO 2 +H 2 O→HCO 3 – +H + →CO 3 2- +2H + Since reverse osmosis memb... -
Effects of Pressure and Temperature on Water Production
2026-03-28
During operation, the permeate flow rate of a reverse osmosis membrane increases with rising pressure and temperature, and vice versa. However, it is important to consider the temperature and pressure range that the membrane element can withstand. The membrane element performs optimally when oper...
