Clean Water Disinfection APPLICATION NOTES

  1. Disinfection In Drinking Water: Choosing The Right Chlorine Analyzer For Your Application
    4/13/2017

    Disinfection is a very important part of the drinking water treatment process, and choosing between an amperometric and colorimetric chlorine analyser is a decision that depends on a variety of factors. Below you will find out why a colorimetric analyser was the right choice for our customer, given their specific situation.

  2. 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.

  3. Flow Meter Enhances Chlorination System Performance For Municipal Water Department
    12/12/2017

    The water municipality at a mid-size city in the Western region of the U.S. serving a population of about 180,000 people needed to address a chlorine disinfection system problem at one of its water treatment plants.

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

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

  5. 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.

  6. 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.

  7. 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."

  8. 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

  9. 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.

  10. 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.
