  • BioSense a Biofilm Monitor and Controller

    Abstract Biofilms (slime) can form on virtually every nonshedding surface, in a nonsterile aqueous environment i.e. anywhere where a water source is present; such as cooling/heating systems, swimming areas and in drinking water purification. These Biofilms can cause a myriad of problems including; harbouring harmful bacteria such as Legionella, inducing corrosion, and reducing ...

  • Biofilm control strategies in industrial processing waters

    Bacterial biofilms cause a number of serious problems for industrial fluid processing operations. Mechanical blockages, impedance of heat transfer processes and microbially induced corrosion result in billions of dollars of losses each year. In engineered systems, such as cooling water systems, food processing, and other industrial applications possible risk to public health and product spoilage ...

  • Global experiences in optimizing biofouling control through Pulse-Chlorination®

    ABSTRACT Cooling water systems provide optimal conditions for settlement and growth of fouling species, e.g. mussels, oysters and barnacles. Excessive biofouling results in major operational upsets and even unplanned shutdowns. Controlling micro- and macrofouling organisms in once-through cooling water systems is key for safe reliable operation. For this, chlorination is globally still ...

  • 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 ...

  • Alternative Disinfection Technology Demonstrates Advantages for Wet Weather Applications – A Pilot Study of Powdered Bromine Technology

    A bromine disinfection technology currently utilized in Japan for Combined Sewer Overflow (CSO) disinfection was piloted by the City of Akron, Ohio. Bromochlorodimethylhydantoin (BCDMH) is a biocide in powdered form that, when dissolved in water, hydrolyzes to hypobromous acid, hypochlorous acid (the active biocides) and Dimethylhydantoin. This unique combination in active biocides can yield ...

  • Sea water treatment for offshore oil & gas pipeline hydrotesting - Case Study

    atg UV Technology have recently designed and manufactured a state of the art, containerised UV disinfection package for the treatment and removal of SRB's (Sulphate Reducing Bacteria) from sea water. The system incorporates two parallel trains of three SX-635-16 UV Systems in series.  To avoid problems associated with maintenance and corrosion, atg UV Technology manufactured all UV systems, ...

  • Mixed Oxidant Replaces “Cocktail” of Chemicals in Power Plan

    Cooling Tower Water Systes Synopsis In 2010 NIPSCO installed two MIOX RIO Mixed Oxidant Solution (MOS) chlorine generator systems on two of the four cooling towers at R.M. Schahfer Generating Station.  After switching to MIOX for cooling tower water treatment, the two towers experienced minimized algae growth, better biocontrol and lower Legionella counts, ...

  • 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 ...

  • From Wastewater Treatment to Sweet Pineapples

    In wastewater treatment, ammonia that is removed from sewage used to be discharged directly to the atmosphere. Nowadays, studies have identified that ammonia emissions are of major concern to air quality. This has led to a new way of thinking. Sulzer offers modern closed-air-loop systems for wastewater treatment that transform ammonia into a common soil fertilizer. This reuse of a waste product ...

  • Toxicological and Environmental Safety Data - Case Study

    Introduction AGRAGEL is a cross-linked copolymer of acrylic acid and acrylamide partially neutralized as potassium/ ammonium salt. The polymer is in its dry form a granulate and forms a gel-like material upon addition of water or aqueous solutions. Due to the cross-linking it is insoluble in water. Uptake of water is facilitated mainly by the negative carboxylic groups of the polymer and ...

  • Mold, Mold Growth and Buildings

    Concern about mold exposures in buildings continues to be a significant issue. The bottom line is that mold has been around for eons and is not going away.  It will grow whenever and wherever buildings get wet and materials suitable for mold growth are present.  The following paragraphs are meant to shed light on mold issues related to microbiology, health and safety, moisture control, ...

  • When it comes to food packaging, what we don’t know could hurt us

    Recent analyses raise disturbing questions about the health and environmental effects of the stuff that encases our edibles. It’s almost impossible to imagine life without flexible, transparent and water-resistant food packaging, without plastic sandwich bags, cling film or shelves filled with plastic jars, tubs and tubes, and durable bags and ...
