Abstract
A filtration assembly including: 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; a bioreactor assembly including: a low pressure vessel comprising a first and second port, and a plurality of spiral wound bioreactors located within the low pressure vessel with each bioreactor comprising a flat sheet having two opposing bio-growth surfaces and a feed spacer spirally wound about an axis; and a fluid flow pathway extending from a fluid feed source: into the first port of the low pressure vessel, through the bioreactors and out the second port of the low pressure vessel, and into the feed port of the high pressure vessel, through the membrane modules and out of the concentrate port and permeate port.
