Abstract In this study, nitrification before and after abrupt cross-transfer in salinity was investigated in two moving bed biofilm reactors inoculated with nitrifying cultures that had adaptation to freshwater (FR) and seawater salinities (SR). FR a

Abstract In upflow anaerobic sludge bed (UASB) reactors, biomass present as granules allows for long solids retention time. Here, granules from a process treating pulp and paper industrial wastewater were successfully applied as inoculum in UASB reac

The anammox activity of a freshwater anammox consortium was strongly inhibited at low-salinity level. Stepwise adaptation from 0 to 3 g NaCl L−1 took 153 days. Further adaptation to high-salinity concentration (from 3 to 30 g L−1) took only 40 da

Integrated and sustainable waste handling is becoming essential in large scale employment of amine-based post combustion CO2 capture and storage (CCS). We have previously proven the feasibility of biological nitrogen removal of amines in a moving bed

This paper describes an experimental study of microbial communities of three moving bed biofilm reactors (MBBR) inoculated with nitrifying cultures originated from environments with different salinity; freshwater, brackish (20‰) and seawater. All r

We examined the effect of ammonium and temperature on methane production in high rate upflow anaerobic sludge bed reactors treating pig manure supernatant. We operated four reactors at two ammonium concentrations (‘low’ at 1.9, ‘high’ at 3.7
