Hollow Fiber Element - RO Membranes

Advanced Reverse Osmosis Technology

Hollow Fiber Element - One of four possible membrane configurations (others are spiralwound, plate and frame, and tubular). Hollow fiber elements are made of extruded cellulose acetate or polyamide material. Pressurized feed water passes across the outside of the fibers. Pure water permeate the fibers and is collected at the end of the element. Hollow fibers were among the first RO systems.

The hollow fiber element does not allow for turbulent flow or uniform flow across the fiber surface making these elements more prone to fouling and scaling. Once fouled they are more difficult to clean due to the inability to get the cleaning solution to the fouled area. Hollow fiber elements are mostly found in seawater desalination applications and limited brackish water applications where fouling potential is minimal.
