Case Study: ATU Valve Monitoring Saves Maintenance Time

Early adoption of valve monitoring technology is effectiveProblem: Art Betker, the sewage system operator for the Rockwood Estates residential community in Rice, Minn., realized he was spending a lot of time making periodic checks of the mechanical distributing valves for the treatment modules. The treatment process utilizes 5:1 recirculation, and each valve was cycling over 200,000 times per year. Occasionally a valve spring would break, preventing even distribution to all modules. If the problem was not detected quickly, treatment would deteriorate causing regulatory problems.Solution: Betker learned about an electronic monitor and early-warning alert system being developed for 6000 Series multi-zone distributing
