Municipal RO Plant Recovery
The municipal reverse osmosis (RO) plant had been in operation for almost 18 years, producing ~290 gpm of permeate water for a city in Iowa, USA. It was one of the fi rst RO plants in the state and the upper Midwest. In May 2008, city operators complained about a loss in system production. In response, the City contracted a RO membrane service provider to perform a cleaning regimen that produced less than satisfactory results. The City then contacted Avista™ who sent an applications services manager to the site.
In this case, restoring flux and rejection with an improved cleaning procedure was just addressing the symptom. Expert troubleshooting knowledge took the diagnosis one step deeper to determine the root cause of the issue.
