Field testing of modified CA membranes to remove PPCPs from drinking water
Presented: 02/25/13
This paper discusses the development of modified cellulose acetate (CA) membranes to increase their surface charge and potentially increase their removal of charged pharmaceutical and personal care products (PPCPs). The objective of this study is to conduct two field tests to evaluate their effectiveness in the removal of ppt and ppb levels of the ...
Hollow Fiber Ultrafiltration of Hydrophobic Natural Organic Matter (NOM) Waters using Different Pretreatment Schemes: Floatation versus Sedimentation
Presented: 02/14/17
There has been only limited research on coagulation/flocculation/floatation as pretreatment for ultrafiltration (UF) membranes in drinking water treatment, and it has concentrated on the treatment of algal-laden waters, i.e., their natural organic matter (NOM) has a low hydrophobic fraction (HPO). The main objective of this study was to investigate...
