  1. 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

  2. Innovative Solutions To Drinking Water Decontamination In Small And Medium Treatment Plants

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

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

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

  4. 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.

  5. Importance Of Measuring UV Transmittance (UVT) For UV Disinfection
    2/1/2013

    UV disinfection systems disinfect water using UV light at the 254 nm wavelength. UV light at this wavelength actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as cryptosporidium and e-coli from reproducing and causing harm.

  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. 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.

  8. 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.
  9. Control Of Drinking Water Clarifiers
    4/13/2017

    "The variable concentration of solids when purging lamella clarifiers creates problems with sludge dewatering. These problems are exacerbated when changing the flocculant. Read the full application note to learn how automatic control of purge cycles for clarifiers using the Sonatax sludge level probe resulted in reduced energy consumption and maintenance at the plant."

  10. 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.
