ph treatment Applications

  • Water treatment

    As a selective oxidizing agent, chlorine dioxide possesses several chemical advantages when compared to the traditional use of chlorine in wastewater treatment. Chlorine dioxide does not hydrolyze in water, and thus it retains its biocidal activity over a broader range of pH. It is also non reactive with ammonia and most nitrogen-containing compounds, and thus effective at lower dose levels than chlorine. It also eliminates phenols, simple cyanides and sulfides by oxidation. Likewise it is effective at odor...

  • Landfill Leachate Treatment

    Effluents from waste (leachate) are highly polluted and must be treated efficiently before they can be discharged into a municipal sewage plant or a local watercourse. Conventional treatment technologies do not suffice. Chemical processes are not economic due to the high pH buffer capacity of the leachate. Hardness and chlorides in the leachate are a problem for many plant components. Besides, process knowhow and operating experience are indispensable for an effective elimination of the harmful ammonia nitrogen....

  • EPR waste minimisation monitoring for wastewater treatment industry

    The EPR regulations have replaced the IPPC regulations and are effective from May 2009 for qualifying companies within the industrial sector and October 2009 within the water sector. They will progressively require industry to minimise waste, reduce product loss and implement improved process control. The legislation will require the operator to self monitor processes and discharges, to demonstrate effective control with particular emphasis on EPR compliance and prevention. The regulating Agency will operate a...

  • Chlorine Dioxide Water Treatment for Power Plants

    Chlorine dioxide is a significant product in the control of algae, planktonic and sessile bacteria, bio-film and scale in power plants, cooling towers, loops and cooling systems. CleanOxide helps maintain the efficiency of heat exchanger surfaces, reservoir intakes and ancillary equipment. Traditional oxidising agents such as chlorine and bromine, on the other hand, are associated with pH constraints and corrosion problems.

  • 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...

  • Headworks Odor and Corrosion Control Using Hydrogen Peroxide

    Hydrogen Peroxide typically controls odors and corrosion at treatment plant headworks by direct oxidation of hydrogen sulfide (H2S) within the wastewater. In the direct oxidation mode, H2O2 is applied to the wastewater 5-30 minutes prior to the point where the odors are being released, generally as the wastewater line enters the plant boundary. The efficiency of hydrogen peroxide treatment depends upon the available reaction time, the level of iron in the wastewater (reaction catalyst), wastewater pH and...

  • Algae control

    Excessive algae growth can throw even the best water treatment processes out of balance. Algae can clog intake screens, fluctuate pH levels, increase chlorine demand, and negatively affect the taste and smell of water. By blocking sunlight within water treatment tanks, you can stop algae growth, reduce chemical usage, and minimize the formation of disinfectant by-products (DBPs). Temperature is better controlled and maintenance associated with algae cleaning is simplified. The results? Better water treatment and...
