  • Scale-up of a Medium Pressure UV System for the Treatment of N-Nitrosodimethylamine (NDMA) and its Advantages Over Low Pressure UV Systems

    Recently there has been considerable concern in California about the detection of N-nitrosodimethylamine (NDMA) in drinking water at levels as high as 900 ppt. NDMA was found to be a carcinogen in animals and assessed as a Class 1 carcinogen. It is currently listed as a priority pollutant on the US EPA National Priorities List. California has set an 'action level' of 20 ppt for NDMA. NDMA is ...

  • Using UV Fluorescent Technology to monitor for organic pollutants

    For many years the water industry has relied on traditional sampling techniques to monitor water quality in a wide range of environments. Traditional tests such as BOD, PH, Dissolved Oxygen and Ammonia have formed the bedrock of monitoring parameters. There are however other ways to establish water quality and UV fluorescence offers an up to date solution for the investigation of ...

  • Hyperion case study - UVC lights enhance air quality

    Located at the center of the Hyperion Wastewater Treatment Plant in Los Angeles, the Pregerson Building was experiencing indoor air quality (IAQ) problems. Built in 2002 to house nearly 400 city employees, the facility rapidly became the source of complaints about poor IAQ and odors. An engineered solution that incorporates both an odor control unit and supplemental ultraviolet- C (UVC) lights in ...


  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...

  • BM Respirometry benefits for activated sludge process management, research and training

    A biological process controlled by non-biological measurements? All treatment plant efficiencies are geared to the waste that they receive. The microorganisms found in the waste need food and oxygen to survive, the food is provided as soluble organic carbon in the waste stream and the oxygen is obtained through the aeration process in the treatment plant. Once a treatment plant ...
