The need for cooling and controlling the temperature of data center equipment presents a major challenge for data centers and their data facility managers. Managing a data center environment based […]
Our most abundant and valuable resource can be detrimental to the very systems that purify it, contain it, and ultimately distribute it to our homes and businesses. Given this, ensuring water is safe for use involves more than just treating it with chemicals to control bacteria and remove contaminants.
Legionnaires disease is a respiratory infection “resulting from aspiration of clumps of Legionella biofilms detached from air and water [HVAC] systems.” Its name stems from a three-day convention of the American Legion held at the Bellevue Stratford Hotel in Philadelphia in July 1976. More than 2,000 attended the annual event. Within a few days after it ended, attendees and others who were at the hotel began showing up in hospital emergency rooms with mysterious respiratory symptoms – just over 200 in all. Despite doctors’ efforts, more than 34 people lost their lives to the illness.
According to the American Hospital Association, about 36.3 million people are admitted to U.S. hospitals each year. We don’t typically think a lot about the availability of a resource as basic as water in medical institutions. But when there is a natural disaster or an unexpected man-made event, the dedicated staff of these institutions have it top of mind. Most hospitals keep back-up generators to handle the power outages usually caused by hurricanes. They don’t necessarily maintain an alternative water supply in case a water main suddenly breaks, or the power outage from a hurricane lasts longer than their generator capacity.
Fresh tap water teems with harmless life, but when water sits inside pipes for an extended period, even for just a few days, more sinister bacterial growth can occur. In fact, when a family leaves home for a week’s vacation, harmful bacteria can grow easily and multiply in static plumbing and water faucets, gathering inside Biofilms — toxic bacterial masses where microbes colonize together in a self-protective layer of communal slime.
