| description | Antibiotics such as amoxicillin and cephalexin are a group of
pharmaceutical compounds in human medicine practice that have been
entered in water bodies. Presence of these compounds in the environment
has raised concerns regarding the toxicity to aquatic organisms and the
emergence of strains of antibiotic-resistant bacteria. Removal of these
substances before entering the aquatic environment as well as water
reuse plant is very important. The objective of this investigation was
to evaluate the impact of hydrophilic and hydrophobic fractions of
Natural Organic Matter (NOM) on the removal efficiency of cephalexin
and amoxicillin, by using two different commercially available
composite NF membranes (TFC-SR2 and TFC-SR3). In addition, the effect
of NOM fractions on retention mechanism and permeates flux behavior was
studied. Amoxicillin and cephalexin were used as models of antibiotics;
alginate and humic acid were used as models of hydrophilic and
hydrophobic fractions of NOM, respectively. It was observed that the
rejection and permeate flux of amoxicillin and cephalexin were
influenced by the membrane characteristics and properties of NOM. The
results showed that as the alginate proportion was increased, the
rejection improved. The permeate flux decreased with increasing
alginate ratio. It was observed that the rejections of amoxicillin and
cephalexin in TFC-SR2 were >97.3% and >95.8% in all experiments,
respectively. In TFC-SR3, the rejection percentage were (95.9%-100%)
and (86.1%-96.3%), respectively. Alginate and humic acid had
synergistic effect on flux decline. In other words, increasing alginate
concentration increased the rate and extent of flux reduction. |
