  • Electrodeionization - Ultrapure water

    Continuous Electrodeionization Process The continuous electrodeionization process (CEDI),  is a system that uses ion exchange resins and electricity  for the production of ultrapure deionized water without chemical processes and without production stops. SIMPEC uses modular systems for the electrodeionization processes. The CEDI modules are installed at the exit ...

  • 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 ...

  • Add polish to high purity water

    Electrodeionization (EDI) has recently gained widespread acceptance by water treatment companies and end users alike for almost all applications requiring high-purity water. EDI has proven to be a reliable, cost-effective solution for both end users and water treatment companies. End users purchasing capital equipment can eliminate on-site chemical regeneration. Water treatment companies selling ...

  • 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 ...

  • A high-performance electropositive filter

    Reverse osmosis (RO) membranes have become the industry standard for purification of any feed water source. They are used extensively for producing high-purity, low-conductivity process water. They are also used for producing ultrapure water from fresh water because RO is presumed to be the ultimate purifier. Because RO filters are readily fouled by colloidal particles and biofilms, some method ...

  • Chloramines

    OVERVIEW When chlorine is added to a water supply containing certain organics, the formation of halogenated organics occurs. Called 'trihalogenated methanes' (THM's) these reaction products are suspected carcinogens and maximum allowable limits in municipal supplies are imposed by the U.S. Environmental Protection Agency (EPA). To reduce the potential for the formation of THM's, many U.S. ...

  • The Benefits Of UV Disinfection In The Pharmaceutical Industry

    The quality standards required for purified water in the production of pharmaceuticals have never been stricter, with manufacturers having to conform to an ever increasing number of international standards. Craig Howarth, Managing Director of Hanovia Limited, introduces a number of interesting new developments in UV technology for disinfection and dechlorination. ...
