  • Methods of Water Purification

    This article is excerpted from 'Pure Water Handbook' published by Osmonics®, Inc. of Minnetonka, Minnesota USA and is printed with permission of Osmonics, Inc. Water treatment can be defined as any procedure or method used to alter the chemical composition or natural 'behavior' of a water supply. Water supplies are classified as either surface water or groundwater. The majority of public or ...

  • Electron beam-based functionalization of polymer membranes

    A new electron beam-based approach for the direct functionalization of polyethersulfone, polyvinylidene fluoride, polysulfone as well as polyacrylonitrile membranes in a one-step procedure is presented. Aqueous solutions of functional molecules were immobilized on the membrane surface by electron beam treatment. The resulting membranes show significantly increased flux and water wettability ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...

  • Crossflow Membrane Filtration Applications in the Beverage Industry

    Abstract The use of crossflow membrane separation technology in the beverage industry has gone from a 'unique processing' approach to a standard unit process for many manufacturers. Applications such as replacement of troublesome diatomaceous earth (DE) filters for juice clarification have been highly successful. Employing reverse osmosis (RO) for apple juice concentration produces potential ...
