Microbial Removal and Integrity Monitoring of High-Pressure Membranes - High-Quality Water - Monitoring and Treatment (90942f)

Intact (uncompromised) RO membranes, whether in flat-leaf or spiral-wound- element form, demonstrated >6 logs virus removal (MS-2 phage). Intact NF membranes in element form showed lower removals ranging from 3 to 5.5 logs. Good correlations were observed between MS-2 phage and the two non-biologic viral surrogates evaluated, Rhodamine WT and fluorescent microspheres, when used to indicate loss of integrity in spiral wound HP membrane systems when such systems were compromised by inducing imperfections in both membrane sheet and in o-ring connectors. Of the non-biologic surrogate viral integrity methods evaluated, only Rhodamine WT is currently practical for application at full-scale, although as a solute, its application does have limitations.
