摘要

RO is seeing widespread use as a core technology for advanced treatment of secondary effluent for the purpose of indirect potable reuse (IPR) and other high level process water applications. As part of an IPR scheme, RO is often relied on to achieve pathogen removal, including virus removal. Currently, there are limited methods for validating RO virus removal. This study utilized a fluorescent dye (Rhodamine WT or R-WT) as a molecular marker for validating a high level of virus removal by a fullscale RO system installed at the Gippsland Water Factory in the State of Victoria, Australia. Validation testing was mandated by the Victorian Department of Health (VDH) to demonstrate compliance with the virus log removal objectives for RO as part of the plant’s Quantitative Microbial Risk Assessment QMRA). Results of the testing showed, that when dosed at a feed concentration of 100 ug/L, an intact 2- stage RO system can achieve ～2.6 log dye removal, with removal most likely limited by feed dye concentration. Further, limited on-line TOC monitoring of RO feed and permeate demonstrated >2.0 log removal at steady-state operating conditions. These results have resulted in VDH awarding the RO system 2.0 log virus removal credit as part of the QMRA.
