Wastewater Odors Applications

  • Premium

    Odor control for wastewater treatment processes

    Natural odor control for wastewater treatment processes. Industrial and municipal wastewater treatment generates odors that can be strong, persistent, and a nuisance to employees, residents, businesses, and industries located near the wastewater treatment plant.

    Chemical Water Treatment for waste water

    Kurita develops products and solutions for the waste water treatment to improve the water quality and respect the legislation and the environment. Due to increased environmental sensitivity and today’s legislative restrictions, most industrial plants which use water already have wastewater treatment plants. The different Kurita Technologies carefully adapts to the needs of each plant through the optimization and improving the water quality and reducing your operating costs. Improve the water reuse in your facilities and work closely with our customers to reduce the discharges to a minimum level is one of our main targets.

    Elimination of mercaptan odor for wastewater lagoons

    Wastewater lagoons are utilized to collect and stabilize wastewater. Approximately one third of all U.S. secondary waste treatment facilities employ some type of pond system. Lagoons can become septic, or contain compounds that product significant odors.

  • Chlorine dioxide for municipal wastewater treatment industry

    Wastewater Deodorization: The formation of hydrogen sulfide often poses a problem for municipal wastewater treatment.  Chlorine dioxide, a powerful oxidant, can be effectively used to control noxious, irritating, or pungent odors from many operations.  Moreover, its unique selective properties permit more efficient application at a lower dosage and cost than chorine, hypochlorite, permanganate peroxide or ozone.

  • Potable 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 control and will oxidize sulfides. Chlorine dioxide is also effective at oxidizing iron and manganese compounds.

  • 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 used in place of bleach, one gallon 50% H2O2 for every 10 gallons of 15% sodium hypochlorite (NaOCl). This generally translates into a break-even cost scenario. Sufficient caustic soda (NaOH) is added to maintain a pH of 10.0 - 10.5 in the scrubbing solution. There is also in practice a process which uses H2O2 in series with bleach to scrub composting odors. This process relies on a series of three packed tower scrubbers: the first is a pH neutral water wash (to remove ammonia and amine odors); the second uses a conventional caustic/bleach solution in which the bleach is purposely overdosed (to oxidize the complex organic sulfur odors); and the third uses a caustic/H2O2 solution (to remove the unreacted chlorine vapors carried over from the second stage). H2O2 + HOCl → HCl + H2O + O2 Typical dose ratios are 0.5 parts H2O2 per part hypochlorite (OCl-), with sufficient caustic soda (NaOH) added to maintain a pH of 8.5 in the scrubbing solution.

  • Dust collection and odor control in waste management sites

    Th turn key plant is composed by three different wet stages. The first stage is a venturi jet scrubber to collect dust and particles, then the second and third stages are deputed to absorb bad smells, such as H2S, Ammonia and Ammines. The absorption takes place thanks to the injection of chemicals (such as Sulphuric Acid, Sodium Hypochlorite and Sodium hydroxide.
