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.
