This slide presentation outlines information on evaluating the addition ofsurface modification via LSMMblending, and theimpact of pore-forming additiveon membrane characteristics andperformance. 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 membraneperformance; flux reduction during the foulingtest with Ottawa River Water (ORW); flux reduction of ORW; natural organic matter (NOM) accumulation; dissolved organic carbon (DOC) removal versus longtermflux correlation; and, summary of modified membraneperformance.
