1.1.5 Membrane Elements

Membrane elements are the key to reverse osmosis. Interleaved layers of semipermeable
membrane, spacer and permeate carrier spiraled around a central permeate tube make up
the element. The spacer allows for movement of the concentrate past the membrane, and
the permeate carrier carries the purified water out of the membrane element . GE Water &
Process Technologies manufactures a patented spiral wound membrane element with a
turbulent flow design. This membrane module collects the purified water within the central
tube, the permeate tube. The E4H RO machine utilizes between 9 and 24 membrane
elements.
