Impact of high chloride wastewater on an anaerobic/anoxic/aerobic process with and without inoculation of chloride acclimated seeds
Thongchai Panswad,Chadarut Anan +1 more
TL;DR: In this paper, the performance of an anaerobic/anoxic/aerobic (2+2+12h of hydraulic retention time) process with and without inoculation of sodium chloride acclimated seeds was investigated using a synthetic wastewater with COD, nitrogen, and phosphorus of 500, 25, and 15 µm, respectively.

TL;DR: In this paper, the performance and kinetics of the activated sludge process treating wastewaters of freshwater and salinewater (10 g/l NaCl and 30 g/L NaCl) origin were investigated using bench-scale, completely mixed reactors operated at different biological solids retention times (BSRT9s) in the range of 3 to 20 d and organic loadings in the ranges of 0.5 to 2.0 kg COD/kg VSS.

Response of biological waste treatment systems to changes in salt concentrations
D. F. Kincannon,A. F. Gaudy +1 more
TL;DR: In this article, the effect of NaCl on the yield of biological solids and on the ability of continuously cultured heterogeneous microbial populations to remove substrate was assessed by changing the salt concentration in the inflowing synthetic waste.

Experiments on the adaptation of escherichia coli to sodium chloride.
TL;DR: The entire adaptive response of the bacteria to a considerable increase in the salinity of the environment could thus be separated into two components: an acclimatization, independent of reproduction, and a selection of those cells with the widest range of potentialities.
