Duraflow announces new DF-ROBR tubular membrane technology for a reverse osmosis (RO) brine wastewater recovery up to 95%.
The wastewater pumps at a high velocity through the membrane modules connected in series with low inlet pressure of 60 psig. The turbulent flow, parallel to the membrane surface, produces a high shear scrubbing action which minimizes deposition of solids on the membrane surface. During operation, clear filtrate permeates through the membrane, while the suspended solids retained in the re-circulation loop are periodically purged for further dewatering.
Duraflow tubular membranes are capable of handling solid concentrations. The membranes, made of PVDF, are cast on the surface of porous polymeric tubes to produce a pore size of 0.1 micron. The chemical resistant property of PVDF allows the use of a range of chemicals – acids, bases and oxidizers for cleaning of the removed fouling substances.
