TL;DR: It was found that as the abundance of each species population increased, both BOD5 and suspended solids from effluents tended to a particular range of values (the optimal range) whereas the standard deviation diminished, suggesting that ciliates are good indicators between 4 and 18 ppm in activated sludge plants.

TL;DR: Results showed that the bacteria and the accompanying microbiota were more abundant in the first flush water whose temperature was lower, and the bacteria occurred in those samples with high HPC and were inversely correlated with high temperatures.

TL;DR: This study shows that microalgal biomass recycling (10% dry weight) increases biomass recovery up to 94% by selecting the most rapidly settling microalgae species without compromising the biomass production and improving the wastewater treatment in terms of TSS removal.

TL;DR: The results suggest that ammonia nitrogen causes a clear but reversible toxic effect on microfauna abundance when its concentrations are around three times higher than that which themicrofauna is used to.

TL;DR: W Wastewater disinfection by EF was also feasible at natural pH (∼7), showing similar abatement of active microorganisms as a result of the synergistic action of generated oxidants like active chlorine and coagulation with iron hydroxides.
