Waterborne pathogens can accumulate in biofilm located within the plumbing system, even if a hospital disinfects its watersystem on a regular basis. The pathogens can grow in dead-ends of the complex building water system and can then be transmitted to patients when the water is used for their care. The advanced Pentair membrane technology is a proven solution to solve the challenge of water purification in hospitals. At point-of-use or at the point-of-entry of a particular high-risk unit.
