This slide presentation outlines information on evaluating the addition of surface modification via LSMM blending, and the impact of pore-forming additive on membrane characteristics and performance. Topics covered include: experimental design and procedures; testing system; experimental results; impact of PES concentration; advancing contact angle analysis; molecular weight cut-off (MWCO); impact of PVP on membrane performance; flux reduction during the fouling test with Ottawa River Water (ORW); flux reduction of ORW; natural organic matter (NOM) accumulation; dissolved organic carbon (DOC) removal versus longterm flux correlation; and, summary of modified membrane performance.
