Product Introduction
The TF4040-SW is a 4-inch seawater anti-fouling reverse osmosis membrane element developed by Huamo Environmental for compact high-salinity desalination systems. Achieving a stable salt rejection rate of up to 99.8% with a minimum rejection of 99.65% and a boron rejection rate of 92%, it delivers outstanding desalination performance in a compact format. The anti-fouling design ensures reliable operation in challenging marine and high-salinity environments with reduced maintenance requirements. It is ideal for small-scale seawater desalination units, shipboard water production, island water supply systems, and compact industrial desalination applications.
