  • The Use Of UV For Dechlorination

    For many years chemical disinfection techniques have been used to provide microbiologically pure water for industrial and domestic use. Free chlorine, typically introduced by municipal water treatment plants in gaseous form, has been employed for many decades as a primary oxidising agent for the control of microbiological growth. Free chlorine can also be introduced through the injection of ...

  • Application of a Medium Pressure UV System for the Treatment of N-Nitrosodimethylamine (NDMA)

    N-nitrosodimethylamine (NDMA) was first detected in 1990 as a problem pollutant in drinking water wells at levels as high as 3,000 ppt in Elmira, Ontario, Canada. The waste from a large chemical plant over many years had led to the contamination of the drinking water wells for the community. After extensive evaluation and testing, it was determined that UV photolysis was the most effective ...

  • 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 ...

  • Closed vessel or open channel UV disinfection systems

    Ultra violet disinfection is now a standard feature in most waste water disinfection systems. UV has also been adopted by the drinking water community, as a barrier against the chlorine tolerant species such as Cryptosporidium and Giardia. The technology is widely favored due to its non- chemical nature, the fact that no subsequent de-chlorination process is required, and its ability to be ...

  • Using Air Strippers for Off-gas Treatment - Case Study

    Two pharmaceutical plants in Puerto Rico used large sequencing batch reactor (SBR) systems to treat their wastewater. The primary treatment was an aerobic bio breakdown of the waste. The were forced to change their treament process because of change in treatment regulations. The new regulations required them to treat off-gas that was coming from the SBRs. They were faced with installing a very ...

  • Explosion Proof UV Lights for Commercial and Industrial HVAC systems

    In the past decade, more and more people have been installing UV lights in their HVAC systems to eradicate harmful bacteria. A timely study from Duke University Medical Center has proven the effectiveness of using UVC bands to disinfect a myriad of dangerous microbes, including drug-resistant bacteria, such as Acinetobacter, Clostridium difficile and vancomycin-resistant enterococci (VRE). During ...

  • Ozone in Cooling Water Treatment

    When commercial ozone generators were first introduced for cooling water treatment, they were marketed as a stand-alone treatment, a cure-all or panacea. We now know this is not the case. Because there have been many misconceptions regarding ozone, this article is intended to review the basics of ozone, its true capabilities and limitations, and its potential benefits in cooling water treatment ...

  • Treatment of 1,4-Dioxane in Stockton, CA

    In the early 1990’s, the volatile organic compounds (VOCs) tetrachloroethylene (PCE) and trichloroethylene (TCE) were discovered in the vicinity of several city water supply wells near the city of Stockton, California. An aggressive, hydraulic containment/water reinjection system was installed to contain the plume and protect the quality of the drinking water. For several years, a treatment ...

  • Importance of Air & Water Testing in Indoor Pools

    Have you ever wondered why your eyes hurt or why you have a cough after swimming at an indoor pool? We all assume that it’s from too much chlorine in the pool but that is false! If the pool staff doesn’t regularly test and monitor both the air and water indoors, the environment becomes very toxic and unsafe to everyone in the building. Water is an essential ingredient for all life as ...

  • Using respirometry for energy optimization in a nitrifying biological wastewater treatment system

    Many wastewater treatment plants use more than 50% of their total energy budget in the aeration basin and, when nutrient removal is included in the activated sludge process, it is very common that the majority of oxygen uptake goes to the nitrification process. For that reason, in most wastewater treatment plants, energy optimization is focused on nitrification management. This information can be ...
