Managing toxic loadings at industrial wastewater treatment facilities can be challenging. Influent from food processing industries can introduce harmful cleaning products. The book Wastewater Bacteria, by Michael Gerardi, explains cleaning chemical surfactants can be harmful to the cell membranes and cellular proteins of wastewater microorganisms.1 Biota with damaged cellular structures may be unable to properly metabolize the organic substrate and nutrients in wastewater.
Bioaugmentation can be used to mitigate the harmful effects of toxicity in wastewater systems. Implementing a concentrated and diverse community of microorganisms can increase functional plant biomass reducing process recovery time from a toxic hit. The following case study outlines bioaugmentation with BioLynceus® ProBiotic Scrubber® II (PBII) and Candy Carbon® (CC) at an industrial sequencing batch reactor (SBR) plant.
