NOM Rejection by, and Fouling of, NF and UF Membranes
OBJECTIVES: The performance of spiral-wound nanofiltration (NF) and ultrafiltration (UF) membranes was investigated in terms of natural organic matter (NOM) rejection and associated NOM fouling. The study objectives focused on • demonstrating the effects of both hydrophobic and electrostatic interactions between NOM components and the membrane surface • determining influential factors (water qu...
متن کاملcontribution of setting to the study of characters and the main idea in e. brontes: wuthering heights and t. hardys: return of the native.
this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...
15 صفحه اولApplication of powdered activated carbon (PAC) for membrane fouling control in a pilot-scale MBR system.
Membrane fouling is considered to be the most serious drawback in wastewater treatment when using membrane bioreactors (MBRs), leading to membrane permeability decrease and efficiency deterioration. This work aims to develop an integrated methodology for membrane fouling control, using powdered activated carbon (PAC), which will enhance the adsorption of soluble microbial products (SMP) and imp...
متن کاملNatural Organic Matter Removal and Fouling in a Low Pressure Hybrid Membrane Systems
The objective of this study was to investigate powdered activated carbon (PAC) contribution to natural organic matter (NOM) removal by a submerged MF and UF hybrid systems. It was found that filtration of surface waters by a bare MF and UF membranes removed negligible TOC; by contrast, significant amounts of TOC were removed when daily added PAC particles were predeposited on the membrane surfa...
متن کاملThe role of NOM fouling for the retention of estradiol and ibuprofen during ultrafiltration
The impact of membrane fouling by natural organic matter (NOM) on the behavior of micropollutants during ultrafiltration (UF) was investigated. Batch experiments with radioactively labeled estradiol and ibuprofen in the presence of NOM model compounds (alginate, Nordic aquatic and Aldrich humic acid) were performed using a hydrophilic and a hydrophobic membrane. The results indicate that the im...
