Emerging Technologies March 2013 Membrane Processes updated 2012 Technology Summary Vacuum Rotation Membrane (VRM®) System Objective: Ultrafiltration of biomass for high-quality effluent with a smaller footprint than activated sludge and a unique approach to cleaning of the membrane surface. Description: State of Development: Emerging. This membrane system employs flat-sheet, ultrafiltration-membrane segments configured into disks rotating on a horizontal shaft. The hydrophilic membrane has a pore size of approximately 38 nm. Sequential cleaning of the rotating membranes is achieved with scouring air introduced next to the shaft at about half the water depth, providing high-intensity scouring of 1/6 to 1/8 of the disk near the 12 o’clock position. The membranes rotate through the scouring section several times per minute. Operating results show that neither back-pulsing nor regular cleaning is required. Average flux is typically 8-12 gal/ft2/day with a suction head of less than 10 feet. (Shear forces introduced by the rotational movement together with the high-intensity air scour remove solids buildup on the membranes to decrease membrane fouling. Chemical cleaning once or twice a year has shown to be sufficient for operating VRM plants. Comparison to Established Technologies: The VRM technology provides similar advantages as other MBR processes using ultrafiltration membranes. The unique feature of VRM is that the membranes are configured into disks rather than tubes or plates and that the disks are rotated for cleaning and to introduce shear forces for fouling control.
