The paper presented a study to demonstrate a method with which higher log removal values for virus can be confirmed using a more appropriately sized tracer compound. Currently RO installations at potable reuse facilities can only achieve a maximum of approximately 2-log virus removal credit based on online measurements of conductivity or total organic carbon (TOC) removal. Overall, the results of this study suggest that the Trasar? system is a promising option for continuous online monitoring of RO membranes and a conservative monitor for virus removal. During this testing, the Trasar? system was able to achieve up to 4-log sensitivity and was responsive to physical and chemically-induced RO system damage.
