SE Series
Industrial High Rejection Brackish Water RO Elements
The S-Series family of proprietary thin-film reverse
osmosis membrane elements is characterized by
high sodium chloride rejection and a smooth, foul-
ing-resistant membrane surface.
SE High Rejection Brackish Water Elements are
used for brackish water desalination and process
stream concentration.
The SE elements feature either a fiberglass or a pa-
tented Durasan* cage outer wrap, 30mil or 50mil
spacer and polysulfone or Noryl plastic parts.

1 These elements are dried then bagged before shipping.
2 Internal diameter unless specified OD (outside diameter).
3 The element diameter (dimension C) is designed for optimum performance in GE
pressure vessels. Other pressure vessel dimension and tolerance may result in
excessive bypass and loss of capacity.
