Duraflow offers their new DF-ROBR membrane technology for RO brine wastewater recovery. Features of the system include:

  • Pre-treatment chemistry that is custom designed for softening and removal of RO (reverse osmosis) fouling components that may include heavy metals, organic matter, silica colloids, biological matter, surfactants and more.
  • According to the company, this low-fouling membrane technology can solve water shortage problems by maximizing reuse and recycle of large volumes of brine wastewater.
  • The wastewater is pumped at a high velocity through the membrane modules connected in series with a 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.
  • Clear filtrate permeates through the membrane, while the suspended solids retained in the re-circulation loop are periodically purged for further dewatering.
  • The membranes, made of PVDF, are cast on the surface of porous polymeric tubes to produce a nominal pore size of 0.1 micron.
