Barrier® M UV Systems for Water Disinfection Applications

The Barrier® M range of UV systems is primarily designed for the treatment of potable water, wastewater, swimming pool and process water with flow rates ranging from 44 to 5000 US gpm (10 to 1150 m3/h).

UV Water Disinfection System - Barrier® M

Barrier® M Series

The Barrier® M systems are equipped with special Wallace & Tiernan® medium-pressure lamps, type WTL. The radiation spectrum of 200 to 300 nm attacks both the DNA and the cell wall, proteins and enzymes of waterborne pathogens. The repair mechanisms of the microorganisms are therefore also destroyed. The Barrier® M reaction chamber is characterized by optimal hydraulics and low pressue loss, ensuring a high efficiency of the UV system.
