Product Channel Spacer - A product channel; spacer  is also known as a "permeate water carrier". In the construction of a membrane element, the product channel spacer is placed between two layers of the flat sheet membrane. This spacer is made using a knit fabric called Tricot, and is used to prevent the RO membrane from closing-off on itself under the high pressure of operation. Permeate water will flow in a spiral path across the product channel spacer into the product collection tube.
