Membrane Preservative Cartridges
The interior of a spiral membrane element, being dark and moist is an excellent breeding ground for microorganism. When spiral elements are used, tested, or operated intermittently, they will probably be exposed to bacteria. During shutdown or storage periods of more than a few days, spiral elements should be disinfected or sterilized by filling the system with a biocidal solution. Up to 40 percent flux loss can occur from biological fouling in elements and modules that have been tested on non-sterile water, then stored on the shelf or in non-operating units for long periods.
To prevent biological growth during storage, shipping, or system shutdowns, it is recommended that RO Systems and membranes be immersed in a solution of AM-88. This solution will not adversely affect membrane flux or performance.
