Volatile fatty acids (VFAs) accumulation is a common problem in anaerobic digestion, which constraining the process. In this study, bioaugmentation was initially adopted as measure to tackle acidification continuous digester. However, after stopped, promotive effect of hard sustain. comparison, combination and Activated charcoal (AC) enabled better reactor performance. The positive impact AC on...

Bioaugmentation by Pseudomonas strains is widely used for the removal of pollutants in wastewater. In this study, we aimed to determine pentachlorophenol (PCP, 800 mg·L<sup>–1</sup>) secondary wastewater bioaugmentation process. We determined effects using three surfactants, namely sodium dodecyl sulfate (SDS), cetyl-tri-methyl-ammonium bromide (CTAB), and Tween 80 PCP removal. effe...

Contamination in subsurface environment is a serious environmental hazard. Main sources of the contamination are petrol, diesel fuel, gasoline at oil refineries, underground storage tanks, transmission pipelines and different industries. Permeable reactive barriers (PRBs), which promising technology to remediate groundwater in-situ, filled with materials for removal contaminants present groundw...

The effect of addition of a microbial consortium (A) with 22 micro-organisms on the large scale (400 m3) bioremediation of municipal waste water contaminated with petroleum hydrocarbons was evaluated. Our results showed that addition of Consortium A was effective in reducing the level of contamination of total petroleum hydrocarbons (TPH) from 1086 mg L-1 to 56 mg L-1after just 21 days and to 1...
