Feed Channel Spacer

Feed channel spacer is an important component of the RO membrane. It also knows as RO’s inner net, flow channel spacer, and feed spacer. It seems simple but plays an important role, it can influence pressures, overall energy consumption, and degrees of membrane fouling. The manufacture of polypropylene net can be traced back to the middle of the last century.

Feed Channel Spacer for RO Membrane manufacturer--HEBEI VIVA NET CO.,LTD

Feed channel spacer, also known as RO feed spacer, is the core inner net for spiral-wound reverse osmosis membrane elements. Made of extruded PP, it separates membrane sheets and builds uniform feed flow channels. It creates mild turbulence to reduce concentration polarization, lower pressure drop and mitigate membrane fouling. The popular 34-mil version features wider channels for energy saving and easier cleaning. Widely used in water treatment, desalination and industrial RO element manufacturing.
