  • 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 ...

  • Preventative control of legionella through real-time bioburden testing

    Abstract: Of the 485,000 annual cases of pneumonia-like sickness in the USA, approximately 15% are attributed to Legionnaire’s Disease. This typically results in  health care costs of over $600 million (1, 2, 3). For the most part, these incidents can be prevented through effective monitoring and treatment. Since Legionella thrive within microbial biofilms and ...

  • Legionnaires’ disease (Legionella pneumophila)-sometimes deadly, sometimes not!

    More than 90% of Legionella cases are caused by Legionella pneumophila, a bacterium that thrives in warm to hot water.  Pipes, tanks, faucets, showerheads, and hot water heaters are ideal breeding grounds for L. pneumophila.  Since infection with Legionella occurs through inhaling the bacterium, any activity in which contaminated water can be misted and subsequently inhaled can lead to ...

  • Neuthox removes legionella bacteria and biofilm - Case Study

    Hotel Terme della Sardegna (Sardinia, Italy) saves 12.000 € yearly by having a clean water system Danish Clean Water is the manufacturer of an ECA generator, which produces the disinfectant liquid, NEUTHOX. NEUTHOX is produced through an electrolysis process, where only electrical power, common salt and water is used, and is a clear 100 % biodegradable liquid which ...

  • Monochloramine and chlorine dioxide for controlling Legionella pneumophila contamination: biocide levels and disinfection by-product formation in hospital water networks

    Legionella colonization in hospital hot water distribution networks was evaluated following 36 months of continuous treatment with monochloramine and compared with chlorine dioxide. Nitrite, nitrate, chlorite, chlorate, bromide, trihalomethanes and haloacetic acids as well as the biocide concentration at sampled points were measured. Only 8/84 samples treated with monochloramine were found ...

  • Surveillance of Legionella species in hospital water systems: the significance of detection method for environmental surveillance data

    Monitoring of hospital water systems to prevent and control nosocomial legionellosis is important from a public health perspective. This study was conducted to survey the prevalence of Legionella contamination of hospital waters. A total of 44 water samples from the hot-water system of 11 hospitals were tested for Legionella by a culture method and a nested polymerase chain ...

  • 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 ...

  • Treated vs. Untreated Cooling Tower Water: Risks for Your Plant

    When an industrial plant or building decides whether or not to invest in a cooling tower water treatment system, it is a decision that shouldn’t be taken lightly. Petrochemical plants, chemical manufacturers, refineries, and all kinds of large buildings and facilities using cooling towers, whether they’re used as part of the industrial process or for cooling/removing heat from the ...

  • Controlling Scale Deposition and Industrial Fouling

    It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance ...

  • 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 ...

  • Using Hazard Analysis and Critical Control Point Water Management Plans to Prevent Legionellosis

    ABSTRACT Legionellosis is an environmental-source disease caused by Legionella bacteria. Many such diseases are prevented using a scientifically-based risk management process called Hazard Analysis and Critical Control Point (HACCP; pronounced “Hassip”). Water Management Plans based on HACCP have been proven effective for preventing legionellosis. Perspective is given for how ...

  • Legionellosis -- Why the Problem Continues

    This year marks the 30 th anniversary of the 1976 American Legion convention of military veterans held in Philadelphia. A mysterious disease outbreak occurred that killed 34 people and debilitated nearly another 200. The media named it Legionnaires’ Disease. In early 1977, the cause of the outbreak had been proven to be a previously unknown waterborne pathogenic bacterium ...

  • Cooling tower case study

    Cooling towers have always been difficult to control. Algae grow in the cooling tower itself and on the grids used. In addition to micro-organisms and biofilm, they reduce the efficiency of the cooling tower. Furthermore the risk of spreading Legionella is a serous factor to be reckoned with. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally ...

  • Legionnaires Disease and 2nd Generation ATP

    As recent events in Quebec, Canada have shown, outbreaks of Legionnaire’s Disease continue to happen around the world.  As our ability to diagnose this ailment improve, it is not surprising that the number of confirmed cases continues to rise.  Conventional wisdom states that the bacteria ...

  • Opportunistic pathogens and faecal indicators in drinking water associated biofilms in Cluj, Romania

    Biofouling occurs without exception in all water systems, with undesirable effects such as biocorrosion and deterioration of water quality. Drinking water associated biofilms represent a potential risk to human health by harbouring pathogenic or toxin-releasing microorganisms. This is the first study investigating the attached microbiota, with potential threat to human health, in a public water ...
