  • An alternative cooling tower disinfectant: On-site generated mixed oxidants

    Favorable temperatures (80-110°F) and availability of nutrients make cooling tower systems ideal places for microbial growth. Accumulation of biofilm impedes proper heat transfer and secretes metabolic products that contribute to microbiologically influenced corrosion (MIC). The films also may propagate and release disease-causing bacteria. Control of microbial growth is traditionally ...

  • Disinfection By-Products (DBP) Precursor Monitoring

    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. DBP’s, such as triahalomethanes (THMs), can occur when the natural organic matter (NOM) that is present in the water is combined with chlorine. More specifically, the portion of ...

  • The Daytona Beach Ralph Brennan Water Treatment Plant Finds On-Site Generation to be a Safe and Economical Solution for Water Disinfection

     ABSTRACT For many years the use of gaseous chlorine at water treatment plants has been an effective and widely used method of disinfection. It is still the most commonly used disinfectant treatment in water treatment plants in the United States. In recent years however, the safety of chlorine gas has come under increased scrutiny. The side effects to chlorine gas exposure at low levels ...

  • Efficient generation of mixed oxidant disinfectants: parametric study on electrode materials and operating conditions

    Electrochemical disinfection is an efficient method used for treatment of drinking water. It has great environmental compatibility as compared to conventional disinfection methods. In this study, the effects of the electrode materials and working conditions were investigated. The experimental results show that the type 1 (iridium oxide-coated anode and cathode) electrode system generated a ...

  • Mixed Oxidants show disinfection benefits for municipalities

    “The most significant advantage over gas chlorination or hypochlorination is an ability to maintain chlorine residuals further along the water distribution system, due to better biofilm removal. Other noted advantages of mixed oxidants are ease of operation with self-cleaning electrolytic cell on-site generators, fewer safety issues in comparison to gas chlorination, and lower costs ...

  • Chemistry of Chlorine Application and Production for the Disinfection of Water and Wastewater

     ABSTRACT A thorough understanding of chlorine and sodium hypochlorite chemistry is essential in optimizing their usage in disinfection of water and wastewater. High price of both chemicals and hazards involved in their transportation to plant sites have prompted many utilities to consider generation of these chemical on-site. A detailed discussion of the critical engineering concepts ...

  • Key Operating Strategies for Chlorine Disinfection Operating Systems

    ABSTRACTChlorine has been used as a standard for disinfecting wastewater for many years. While being the standard There are many levels of automation for control of disinfection. To select the best control approach for your facility both control strategies and chlorination chemistry must be understood. Permit conditions must also be fully identified; organism concentrations and operational data. ...

  • Treating Taste & Odor and Disinfecting Drinking Water with UV

    Cornwall is a city of nearly 60,000 people in Ontario, Canada. It is located on the St. Lawrence River, approximately 1,700 km from the Atlantic Ocean and 2,000 km from Lake Ontario. The city draws its drinking water from the St. Lawrence, a reliable and generally good-quality source. However, in the late summer and early fall, dying algae from algae blooms during the warmest months often ...

  • Microwave UV: A New Wave of Tertiary Disinfection

    Currently UV disinfection technologies available for use in drinking water and water reuse applications typically utilize one of three types of mercury UV lamps. These three types of mercury UV lamps include low pressure, low-pressure high-output, and medium-pressure lamps. All of these lamps contain electrodes that facilitate in the generation of UV radiation. These electrodes are of delicate ...

  • Sugar Syrup Disinfection – Spain and New Zealand

    Hanovia Sugar Syrup UV Systems Background Liquid Sweeteners are produced from sugar beet, sugar cane, corn, starch and artificial substances. These sweeteners are added to final products throughout the Beverage and Food industries, and therefore must be treated to comply with all global regulations for product hygiene. The common methods used for ensuring microbiological quality of ...

  • Wastewater disinfection for reclamation uses with Pacs8 system

    In this article Mr. Luukkonen explains wastewater reclamation for irrigation use in general terms. More specifically he describes use of Pacs chemical and Pacs 8 system in wastewater post-disinfection and its advantages over other technologies. Widely used wastewater disinfection methods are chlorine based chemicals, ultraviolet (UV) radiation, ozonation and more recently treatment with peracetic ...


  • Factors Affecting Disinfection and Stabilization of Sewage Sludge

    ABSTRACTEffective disinfection and stabilization of sewage sludge prior to land application is essential to not only protect human health, but also to convince the public of its benefits and safety. A basic understanding of the key factors involved in producing a stable biosolid product is a necessary component to ensuring that effective disinfection and stabilization are achieved. Key stressors ...

  • Sustainable, Low-maintenance Disinfection for Onsite Systems

    Most of the regulations applicable for onsite wastewater treatment system are based on the use of native soil for effluent dispersal. However, there are more and more situations where dispersal of effluent in native soil is impossible: repairs of existing systems on undersized lots for implementation of required dispersal fields: sites located in soils having low permeability: or where the ...
