2.5 Inch Seawater Desalination RO Element

By optimizing the structure of membrane element, 2.5 Inch Seawater Desalination RO Element increases the permeate flow, and requires fewer elements for same permeate flow. Seawater Desalination RO Element is characterized by low operating pressure, low investment in equipment, excellent rejection rate and reliable performance, and its high salt rejection can ensure the production of the drinking water from seawater simply through one-pass RO design.

SKU: N/A Category:

Applicable to treatment of seawater and high-concentration brackish water, the SW series of membrane element is designed for various industrial water treatment, such as seawater desalination, high-concentration brackish water desalting, boiler water replenishment for power plant, and is also applicable to various fields such as recycling of waste water, concentration and reclamation of such substances with high additional value as foodstuff, pharmaceuticals, etc.
