remove chlorine from water Applications

  • 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...

    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...

  • Chlorine Dioxide Water Treatment for Oil and Gas Refinieries

    Injecting chlorine dioxide into a well is an established technique for removing sulphides and sulphates from oil and gas wells. CleanOxide Chlorine Dioxide is a practically pure solution of chlorine dioxide. It rapidly oxidises the naturally occurring iron compounds, and is also effective at breaking up and removing organic solids and added polymers.

  • Cyanide Treatment with Hydrogen Peroxide

    Cyanides are used in a number of chemical synthesis and metallurgical processes (as simple salts or cyanide complexes). As a class, cyanides are highly toxic and must be destroyed or removed from wastewaters prior to discharge. The most common method for treating free or simple cyanide is alkaline chlorination. However, chlorination of cyanide results in highly toxic intermediates (e.g., cyanogen chloride) and, if organic material is present, chlorinated VOC’s. These compounds, together with the residual chlorine,...

  • Water treatment for hospitals

    Horticultural and greenhouse operations are facing increasing challenges in dealing with sanitation issues related to water treatment. Over the course of growing a crop, pathogenic microorganisms accumulate and algae flourish on moist surfaces posing a constant threat to plants and produce. The main challenges lie the areas of irrigation water, elimination of biofilm and algae control. Existing biocidal products, while effective in killing algae, are not effective in removing biofilm from the water lines. The...

  • Odor Scrubbers Applications with Hydrogen Peroxide

    Hydrogen Peroxide as a Replacement for Sodium Hypochlorite Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution. Step 1: H2S + NaOH → NaSH + H2O Step 2: 4H2O2 + H2S → H2SO4 + 4H2O Typical dose ratios are 5 parts H2O2 per part H2S or, when...

    Ultraviolet disinfection systems for the process water

    Water is often used as a product, or as part of the manufacturing process. In many industrial applications, processes are chemical (chlorine) intolerant, and UV is widely adopted. atg UV Technology engineers will be pleased to discuss solving disinfection problems with you. As well as a powerful disinfectant, UV is used to remove chlorine, chloramines, ozone, bromine, and a wide variety of contaminants from industrial process water. Within micro-electronics facilities for example, UV is used to remove Total...
