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.
