Effect of water matrices on removal of veterinary pharmaceuticals by nanofiltration and reverse osmosis membranes

Assessment of the hindered transport model in predicting the rejection of trace organic compounds by nanofiltration

“…It indicates that NF270 was more permeable than HL. The determined water permeability generally matched well with that reported previously (2.50×10 -6 m/s/bar for HL and 2.6−4.7×10 -6 m/s/bar for NF270) [11,33,34].…”

Investigation of ciprofloxacin removal from aqueous solution by nanofiltration process

“…In addition, solutes can be rejected on NF membrane by one or a combination of three basic mechanisms including size exclusion (sieve steric effect), charge exclusion (electrical, Donnan), and physico-chemical interactions between solute, solvent and membrane (Yoon et al, 2006;Acero et al, 2010;Dolar et al, 2011;Sun et al, 2011;Vergili, 2013). Moreover it is also reported in the literature that size exclusion in tight membranes and charge exclusion and physicochemical interaction in the other membranes were more effective mechanisms in membrane filtration (Dolar et al, 2011).…”

Biodegradation of Wastewater Containing High Concentration of Sulfamethoxazole by Antibiotic Adopted Biofilm in Attached Growth Bioreactor

“…However, for HRT greater than 36 h, there was no significant improvement in COD removal efficiency. The maximum COD removals using COD concentrations of 8,000 mg/L at various HRTs (12,24,36,48, and 60 h) were 75, 86, 96, 96.6, and 97%, respectively. In NRBC, the optimal HRT for desired rate of COD removal was 36 h. So the optimal HRT for the desired rate of COD removal was considered to be 36 h.…”

“…The methods are frequently used in antibiotic removal consist of biological treatments such as conventional activate sludge (CAS), membrane bioreactor (MBR) in combination with methods like microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO), advanced oxidation processes (AOPs) and adsorption to activated carbon [20][21][22][23][24]. In several studies, MBR was considered a suitable alternative to CAS systems for antibiotic removal [1].…”
