  • 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 ...

  • Chemical disinfection of Legionella in hot water systems biofilm: a pilot-scale 1 study

    Legionella bacteria encounter optimum growing conditions in hot water systems and cooling towers. A pilot-scale 1 unit was built in order to study the biofilm disinfection. It consisted of two identical loops, one used as a control and the other as a ‘Test Loop’. A combination of a bio-detergent and a biocide (hydrogen peroxide + peracetic acid) was applied in the Test Loop three times under the ...

  • About TecH2O

    Who is cleaning your cooling tower? With warmer weather on the way, it will soon be time to put cooling towers back into service.  According to legislation passed by New York State effective 11/15/2015, “All owners shall ensure that all cooling towers are cleaned and disinfected when shut down for more than five days” and “any person who performs cleaning and ...

  • Ozone systems for beginners

    This paper is intended for people who know a cooling tower when they see one but have little or no knowledge of their care or what part ozone plays. I have tried to make this as simple as possible and there is even a block diagram on the last page to help you out. Ready? Okay, here is what you need to know first: The sole function of ozone use in evaporative cooling towers is to disinfect water. ...

  • 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, ...

  • Inactivation of Legionella with the DiaCell® water treatment technology

    Legionella constitutes a new and increasingly stronger con-tamination risk many of water systems, such as cooling towers or hot sanitary water distribution networks. European certifica-tions impose concentration limits of 1’000 Cfu/mL [1], waters with higher levels must be treated. At levels higher than 100’000 Cfu/mL the installations must be stopped and disin-fected immediately. Many ...


  • Biofilm Control for Industrial Waters

    Industrial operations can face a number of serious problems due to bacterial Biofilms growing in process water systems and cooling tower waters. Biofilm-induced corrosion, mechanical blockages and impedance of heat transfer processes result in huge monetary losses each year. In engineered systems, additional risks of biofilm-mediated contamination include negative public health consequences and ...

  • Controlling scale in water systems helps prevent legionella

    The Legionella bacterium, Legionella Pneumophila (LP), the fundamental agent of Legionnaire’s Disease, is a water-based organism, which causes infection when inhaled in an aerosol form. Legionnaires' Disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness ...
