abstract = {Two pilot-scale hybrid moving bed biofilm reactor-membrane bioreactors were operated in
 parallel for the treatment of salinity-amended urban wastewater under 6 hours of hydraulic retention
 time and 2500 mg L-1 total solids concentration. Two salinity conditions were tested: the constant
 salinity of 6.5 mS cm-1 electric conductivity (3.6 g L-1 NaCl) and the tidal-like variable salinity with
 maximum 6.5 mS cm-1 electric conductivity. An investigation was developed on the biofouling
 produced on the ultrafiltration membrane surface evaluating its bacterial community structure and
 its potential function in the fouling processes. The results showed that biofouling was clearly affected
 by salinity scenarios in terms of a-diversity and  β-diversity and bacterial community structure,
 which confirms lower bacterial diversity under variable salinity conditions with Rhodanobacter and
 Dyella as dominant phylotypes. Microorganisms identified as bio-mineral formers belonged to genera
 Bacillus, Citrobacter, and Brevibacterium. These findings will be of help for the prevention and control
 of biofouling in saline wastewater treatment systems.},
