This 2-year effort involved pilot studies followed by the start-up, procurement, design, operation, and trouble shooting of an MF/RO system treating water from the City of San Diego’s recycled water system. Pall’s MF system was selected to serve as the pretreatment process for the 0.3 MGD facility located at Toppan Electronics. Toppan required 18 meg-ohm water for rinsing circuit boards. At first, the RO membranes experienced rapid fouling and frequent cleaning. A process evaluation identified the source of the fouling and returned the facility to semiannual cleanings.
