The PARCC Side CWP treatment process is designed around the use of GE/Zenon Membranes for producing high quality final effluent water. At PARCC Side, over 6.2 million membrane fibers, each 7 feet long with a pore size of 0.04 microns (a thousand times smaller than a human hair) are used.

The animation here shows how each membrane fiber allows water to pass through these small pores while rejecting compounds larger than 0.04 microns such as solids and bacteria. The animation also illustrates how membranes are backpulsed to clean the pores as needed.
