abstract = {Ultrafiltration membranes associated with in-line coagulation and hydraulic flocculation were applied for antibiotic-resistant
bacteria removal during Nervión river water potabilization. The study was conducted at pilot scale with an ultrafiltration
module equipped with three hollow fibre polyvinylidenefluoride membranes (0.04 μm nominal pore size) with in-line precoagulation–flocculation. The system operated continuously with constant dose of 20 mg FeCl3/L and a stable production
of 50 L/h (18.5 lmh), operating in vacuum. All physico-chemical water quality parameters analysed improved, but the yields
were variable, highlighting the low capacity to remove organic matter, with a significant influence of influent concentration.
A high capacity to retain bacteria was observed for ultrafiltration membranes with total absence of several faecal indicators
in the effluent, but the presence of total aerobic bacteria and occasionally faecal coliform or even E. coli strains casts doubt
on the microbiological quality of the treated water. Most of the isolated strains in effluent samples were antibiotic-resistant
bacteria with a significant percentage of multi-antibiotic-resistant bacteria, which increase the one observed for the isolated
strains from influent. Antibiotic-resistant bacteria to β-lactams, macrolide and the cotrimoxazole antibiotic groups were
frequently detected in effluent samples.},
