SE series

Summary

Product identification

The SE Series comprises industrial high-rejection brackish water reverse osmosis (RO) elements. These elements feature S-Series, thin-film reverse osmosis (TFM*) membrane technology, characterized by high sodium chloride rejection and a smooth, fouling-resistant membrane surface.

SE elements are designed for brackish water desalination and process stream concentration. They are constructed with either a fiberglass or a patented Durasan* cage outer wrap, 30mil or 50mil spacers, and polysulfone or Noryl plastic parts.
