In late 2011, The City of New Buffalo, Michigan, completed an expansion and upgrades to their existing 40-year-old Water Treatment Plant. Part of these upgrades included the addition of a third filter building to handle one million gallons per day, and with that, the requirement to add chlorine gas scrubbers to be on standby in the event of an emergency. PureAir’s Sentry™ Emergency Gas Scrubber (EGS) and Safetysorb adsorbent media were chosen for the job. A few years later, the municipality found itself in the terrifying situation of a leak, and all were relieved that the SentryTM EGS was onsite.
