Abstract
A filtration assembly including: i) a hyperfiltration assembly including: a high pressure vessel including a feed port, concentrate port and permeate port, and a plurality of serially arranged spiral wound hyperfiltration membrane modules; ii) a bioreactor assembly including: a plurality of spiral wound bioreactors each comprising a flat sheet having two opposing bio-growth surfaces and a feed spacer spirally wound about an axis (Y); and iii) a fluid flow pathway adapted for fluid connection with a fluid feed source and extending in a parallel flow pattern through the bioreactors, and subsequently into the feed port of the high pressure vessel, successively through the spiral wound hyperfiltration membrane modules in a serial flow pattern and out of the concentrate port and permeate port.
