EVOQUA has developed the Barrier® M range of UV technology, specifically developed for the treatment of swimming pool and processed water with flow rates ranging from 60 to 5900 US gpm (15 to 980 m3/h). The Barrier® M systems have a built-in Wallace & Tiernan® medium-pressure lamps that reduce operation costs. Further, the DNA and cell wall, proteins and enzymes of water-borne pathogens are destroyed by the Barrier® M methods thru radiation spectrum of 200-300nm. This ensures thorough disinfection as the repair mechanisms of the microorganisms are lost.
