FC-0115-Koch_PURONKoch Membrane Systems Inc.’s PURON MBR hollow-fiber ultrafiltration membrane bioreactor series is a solution for industrial and municipal wastewater treatment that is designed to reduce energy, minimize downtime, and increase flux in a cost-efficient manner.The PURON MBR single header for wastewater treatment plants features reinforced PVDF (polyvinylidene fluoride) hollow fibers that are fixed only at the bottom to eliminate the buildup of hair and fibrous materials that typically clog the upper ends of other modules. Solids and particulates, including bacteria, remain on the outside, while permeate is drawn through the membrane to the inside of the fibers.As part of the PURON line, PURON MBR modules feature the aeration nozzle in the center of the fiber bundle, scouring the entire length of the fibers and minimizing power consumption.
