Microbiological Control in Thin Film Composite Membrane Systems using a High Purity Chlorine Dioxide Solution

Controlling microbiological growth in reverse osmosis systems has proven more challenging then treating other industrial water systems. The polymer structures comprising the membrane material are susceptible to degradation by strong halogen based oxidants such as chlorine and bromine. The control of microbiological growth on reverse osmosis membranes is particularly problematic with the prominence of biofilms. This paper will discuss the MICROBIOLOGICAL CONTROL IN THIN FILM COMPOSITE MEMBRANE SYSTEMS USING A HIGH PURITY CHLORINE DIOXIDE SOLUTION.
