Reverse osmosis (RO) has played an important role in the practice of potable reuse yet there remains a substantial discrepancy between its actual performance and awarded pathogen log removal credit. The primary objective of this study was to evaluate alternative surrogates, both naturally occurring as well as seeded to RO feed water, that offer hig...

The current study summarizes findings of over 9-month long optimization study evaluating different chemical dosing strategies to address common scalants, such as calcium phosphate, on reverse osmosis membrane systems used in municipal wastewater treatment for potable reuse. The type of project testing different dose strategies in this case at demon...

This paper will focus on brining an important issue of oxidative damage of RO membranes by the often overlooked bromamines residual that can form in waters containing high levels of bromide, such as municipal wastewater. The key issue for RO system operators and managers is understanding how the potential for the formation bromamines residual depen...
