I recently completed a year-long study on a municipal lagoon that accepted some waste from food processors. We sludge judged the lagoon as well as looked at the bioactivity throughout the water column by quarterly measurement of the ATP for a year. The highest level of bioactivity was in the sludge layer!
Over the year, we saw that toxic/septic impacts also inhibited the bioactivity of this layer, although delayed compared with the rest of the water column. What was exciting was seeing how the bioactivity increased as the sludge was stimulated with our Bio Energizer® product. Toward the end of the year of Bio Energizer® application, the bioactivity dropped but it correlated with the reduction of the organics in the sludge layer. Which makes sense: less biomass, less bioactivity.
Overall, it was very exciting to see how bioactive the sludge layer was and that, when it is stimulated, it can bioremediate the organics itself with just a little biostimulant push.

How to Reduce SVI and Foam in Activated Sludge Plants
In this short video, Shawn Whitmer, PE, discusses how foam and settling caused by filamentous bacteria can create problems for municipal activated sludge wastewater treatment plants. Our Probiotic Solutions® liquid stimulant product, Bio Genesis®, can help facilities take a bioremediation approach to improve treatment performance; reduce foam, SVI, sludge, and FOG; and decrease energy costs.
