Water Dechlorination Applications

  • Premium

    Ultraviolet disinfection systems for the de-chlorination industry

    The purpose of de-chlorination is the removal of free chlorine and combined chlorine compounds from potable water, as supplied by municipal water supplies. Chlorine will oxidize the surface of thin film composite polyamide membranes, causing the membrane to lose its ability to repel or reject salts. As a result, the membranes used in Reverse Osmosis (RO) or Electro-deionisation (EDI) systems will exhibit shorter lifetimes when exposed to chlorine in the water they are treating and membrane manufacturers will usually specify an upper limit to ensure a suitable life of the membrane. As a result, it is usual to use a method of dechlorination upstream of the RO or EDI system.

    Water Treatment Solutions for Hydrogen Sulfide

    Sulfates and hydrogen sulfide are both common nuisance contaminants. Although neither is usually a significant health hazard, sulfates can have a temporary laxative effect on humans and young livestock. Sulfates also may clog plumbing and stain clothing. Hydrogen sulfide produces an offensive `rotten egg` odor and taste in the water, especially when the water is heated.

  • Water quality monitoring systems for high water purifier industry

    The monitoring of “Ultra Pure Water” or “High Purity Water” requires the lowest possible detection limits for process analyzers. Resistivity is often around 18 MΩ. Dedicated instruments can detect infinitely small amounts (ppt e.g. parts per trillion) of ions.

  • Industrial water TOC and Color removal from water

    All surface waters contain varying amounts of naturally occurring organic acids. The most commonly encountered being tannic and humic. These substances have varying molecular weights and varying amounts of carboxylic functionality. There has been much interest in the removal of these substances from drinking water supplies due to their tendency to form THM`s when chlorinated. They can be removed effectively by use of anion exchange resins operated in the chloride cycle. Because the organics can be removed by regeneration with brine, this technology is far most economical.
