  • Factors Affecting RO Membrane Performance (.pdf)
    Reverse osmosis (RO) technology can be a complicated subject, particularly without an understanding of the specific terminology that describes various aspects of RO system operation and the relationships between these operating variables. This bulletin defines some of these key terms and provides
  • FILMTEC Membranes: Basics of RO and NF Historical Background
    Since the development of reverse osmosis (RO) and ultrafiltration (UF) as practical unit. operations in the late 1950's and early 1960's, the scope for their application has been. continually expanding. Initially, reverse osmosis was applied to the desalination of seawater and brackish water
  • Improving Outlet Water Quality of RO and EDI Systems (.pdf)
    RO membranes coupled with EDI/CDI technology are rapidly gaining acceptance in the production of high purity water. Coupling the two technologies offers many advantages to the conventional RO mixed bed system design. The overall performance of a RO-EDI/CDI system can be improved by removing
  • Chinese Chemical Plant Optimizes Water Treatment by Replacing Double Pass RO with a Single Pass RO and Liqui-Cel (R) Contactor System (.pdf)
    Electrodeionization (EDI) is widely used in many industrial water treatment systems throughout the world. In order to maximize the operating stability and life expectancy of an EDI system they were often designed with double pass RO using caustic injection pretreatment. However, in response
  • DOW TM UF and RO Technology (.pdf)
    DOW TM Ultrafiltration (UF) modules and DOW FILMTEC TM elements have been installed to purify well water used as process water for soft drink production
  • GE's RO System Helps Unilever Reduce Water, Natural Gas Consumption and Chemical Usage
    Case study copyright of General Electric Company. Used with permission. In the face of rising and unpredictable energy prices, the ongoing campaign to improve energy efficiency is necessary for the Unilever plant in Rexdale, Ontario to remain competitive. The Rexdale plant consumes huge quantities
  • MBF Filters Excel in Ethanol Plant (.pdf)
    An ethanol production plant required RO treated water for their boilers, cooling towers, and fermentation process. In all cases the incoming water was first treated by an RO membrane. Additional post RO treatment was then used to meet the water quality requirements of the end use of the water
  • Flat Sheet Membrane Specifications
    This table compares the specifications of RO, NF, UF, and MF flat sheet membranes for several manufacturers.
