Natural organic matter (NOM) is universally recognized as a major foulant of membranes used for drinking water treatment. The fouling has been attributed to adsorption of NOM in membrane pores and/or to formation of a gel layer that covers the membrane surface. Colloids, humics, and polysaccharides have each been implicated as major contributors ...

Pilot and lab tests were ran to prove effectiveness of HAOPs for removal of Natural Organic Matter (NOM) from surface waters. HAOP can be used as an adsobent in a precipitation method before MF (microlfiltration) or UF (ultrafiltration) or can be used as a coating on the membranes themselves. Effectiveness will be determined by improvement and stab...

Pilot and lab tests were ran to prove effectiveness of HAOPs for removal of Natural Organic Matter (NOM) from surface waters. HAOP can be used as an adsobent in a precipitation method before MF (microlfiltration) or UF (ultrafiltration) or can be used as a precoat on the membrane itself. varying water quality and operational factors like pH and ion...

This PowerPoint describes research to use microgranular filtration media to isolate fouling from a membrane surface. Captures Natural organic matter ( NOM) and integrates adsorption and granular media filtration in a thin, permeable, back-washable layer. Heated aluminum oxide particles were used for the tests....

This paper presents and investigation into two pretreatment processes for Natural organic matter (NOM) removal and fouling control of a low-pressure membrane.. Heated aluminum oxide particles (HAOPs) and powdered activated carbon (PAC), either alone or mixed, were used as adsorbents. The mixed adsorbents enhanced NOM removal compared to an equal to...
