In water recycling applications, the prevention of microbial-related disease is of utmost importance because of the acute nature of infection of waterborne pathogens and the potential for rapid spread throughout the population. Consequently, when evaluating treatment processes employed in water reuse scenarios, focus on the removal of microorganisms is both warranted and necessary. Further, as interest in both indirect and direct potable reuse increases, the need for protection from potential microbial disease transmission via water reuse has become even more pronounced.

Today, microbial protection is often measured in terms of the capability of treatment processes to remove pathogens. The concept of achieving a target log removal value of microorganisms is commonly practiced today for demonstration of process efficacy. However, in many instances, only a 2 log virus removal credit is granted for this process since there is currently no efficacious practical method to monitor for RO membrane integrity when greater virus removal is demonstrated.

This webcast will present results from a WateReuse Research Foundation study (12-07)  on the evaluation of RO membrane integrity techniques. Discussion will focus on (1) results from a literature review on state of the art techniques, (2) outcomes from a stakeholder workshop on RO integrity monitoring, and (3) bench and pilot scale results.
