Influence of Bioaugmentation Strategy of Activated Sludge on the Co-Treatment of Reject Water and Municipal Wastewater at a Decreasing Temperature
In the present study, the influence of bioaugmentation strategy on co-treatment of 13% v/v reject water and municipal wastewater at decreasing temperature was evaluated. The experiment was performed in two equal laboratory sequencing batch reactors with the active volume of 8 L. Each one was operat...

The SBR A was bioaugmented with a mixture of wild-living Bacteria and Archaea in a dose 0.25 ml. While the comparative reactor (SBR B) was non-bioaugmented, the Archaea product was replaced with an equal volume of dechlorinated tap water.
