  • Legionella, water treatment and energy saving

    We can help improve health and safety and increase energy reduction. At the moment you probably keep water temperatures above 60°C and you probably undertake regular chemical or thermal water system treatments and shower head treatments, all to prevent the growth of Legionella in your water system. There are several reasons to do this including legal, safety, ...

  • 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 ...

  • 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 ...


  • 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 ...

  • The presence of opportunistic pathogens, Legionella spp., L. pneumophila and Mycobacterium avium complex, in South Australian reuse water distribution pipelines

    Water reuse has become increasingly important for sustainable water management. Currently, its application is primarily constrained by the potential health risks. Presently there is limited knowledge regarding the presence and fate of opportunistic pathogens along reuse water distribution pipelines. In this study opportunistic human pathogens Legionella spp., L. pneumophila ...

  • 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 ...

  • Harvested rainwater quality: the importance of appropriate design

    This paper summarises the physicochemical and microbiological quality of water from a rainwater harvesting (RWH) system in a UK-based office building. 7 microbiological and 34 physicochemical parameters were analysed during an 8 month period. Physicochemically, harvested rainwater quality posed little health risk; most parameters showed concentrations below widely used guideline levels for ...

  • A Look at the Impact of Proposed Water Standard to Prevent Legionnaires` Disease

    From the standpoint of water treatment industry experts, failure to prevent legionellosis (or Legionnaires’ Disease) is the most significant water treatment problem today. Essentially every case of the disease is the result of exposure to inadequately managed building watersystems, and both utility and potable water systems can be the source of the hazard (i.e., Legionella bacteria). In ...
