Brief Introduction
The SW series is an aromatic polyamide composite membrane element developed by UMEK for seawater desalination.
The membrane elements are characterised by low operating pressure, low investment in equipment and good and stable desalination performance. With a maximum desalination rate of 99.85%, it is possible to obtain drinking water from seawater through primary reverse osmosis.

On July 27, 2024, my colleague Carlson and I departed from Terminal 2 of Beijing Capital International Airport and arrived in Tashkent, the capital of Uzbekistan, after a 6-hour flight. Uzbekistan is an inland country in Central Asia. Russian is the common language, with a population of 36.8 million
On April 6, 2024, two representatives from our company, Youmankang, arrived in Lebanon, a country in the Middle East known for its breathtaking landscapes. With buildings nestled on hillsides, water trucks can be seen everywhere on the streets, indicating the underdeveloped seawater desalination tec
Why should the RO membrane system with reverse osmosis scale inhibitor be pretreated?The purpose of pretreatment is to remove or reduce the substances in the feed water that may cause membrane contamination, scaling and damage to the permissible range of the reverse osmosis membrane system, so as to
