Huamo SW22-4040 Sea water RO membrane, 78ft2 (7.2m2), Huamo (CAT#: STEM-GMAE-4858-LGZ)

SW22 elements can separate salts from water and increase permeability while offering superior salt rejection.

Suitable for：
1. new-built or existing ROsystems.
2. high quality permeate while minimizing unitcost.
3. various operating conditions with 4″and8″elements.
