  1. Control Of Active Chlorine Disinfection By-Products (DBPs) Of Drinking Water Using The THM Plus Method
    4/13/2017

    Determining trihalomethane levels using standard analytical methods requires expensive equipment and highly qualified personnel, which also means that analysis costs are very high. For these reasons, trihalomethane analysis poses a serious problem for companies that supply drinking water. Read the full application note to learn how two drinking water laboratories improved quality control of water delivered to end users.

  2. Removal Of Chloramines With Activated Carbon
    12/30/2013

    In order to reduce the formation of harmful disinfection byproducts in drinking water, alternative disinfectant use has become increasingly widespread. Monochloramine is a leading alternative disinfectant that offers advantages for municipal water. This tech brief details the removal of monochloramine using activated carbon.

  3. Disinfection By-Products (DBP) Precursor Monitoring
    2/1/2013

    Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine.

  4. Benefits Of UV Transmittance (UVT) Field Testing For Selling & Servicing UV Disinfection Systems
    2/1/2013

    The Real UV254 'P' series portable meters can be used to measure UV transmittance (UVT) in a number of situations, and are especially beneficially when working with small UV disinfection systems. The following cases outline two situations in which Real Tech's portable meters are invaluable.

  5. Free Chlorine Measurement In Drinking Water Treatment
    12/21/2005

    Before water can be used as a safe and reliable source for drinking water, it must be properly treated. Since water is a universal solvent, it comes in contact with several different pathogens, some of which are potentially lethal, and inactivation is accomplished through chemical disinfection and mechanical filtration treatment. This treatment consists of coarse filtration to remove large objects and pre-treatment which includes disinfection using chlorine or ozone

  6. Activated Carbon And Adsorption Of Trichloroethylene (TCE) And Tetrachloroethylene (PCE)
    12/30/2013

    Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.

  7. Application Note: Ozone Measurement In Potable Water
    3/1/2010

    Ozone is a powerful oxidizing agent that can be used to destroy the organic compounds that affect the taste and odor of potable water. Environmental concerns have led to increased use of ozone because, unlike chlorine, it does not form hazardous by-products.

  8. Comparison of UV vs. Sodium Hypochlorite (Fact Sheet)
    11/23/2011

    Hypochlorite has some significant environmental concerns associated with DBPs and residual toxicity.

  9. Measuring The Chlorine Content In The Emergency Chlorination Of Waterworks
    12/14/2011
    Many municipal waterworks perform no permanent disinfection of drinking water. However, in many cases a process known as emergency chlorination takes place. The process is switched on in case of need, adding chlorine to the drinking water as a disinfectant.
  10. Innovative Solutions To Drinking Water Decontamination In Small And Medium Treatment Plants
    9/21/2017

    Air stripping technology effectively removes VOCs, THMs, and CO2 for improved adherence to water quality regulations.
