Wastewater treatment plant lagoons present several challenges. Decomposing organic matter can cause strong, foul odors. Also, as sludge accumulates at the bottom of lagoons over time, effective volume and treatment efficiency are reduced. Contributing factors to these problems include hydraulic overloading, organic overloading, and nutrient imbalance.
Formula 60 contains specific strains of bacteria that can enhance the natural biological processes occurring in WWTP lagoons. The microbes in Formula 60 thrive in the prevailing conditions of WWTP lagoons such as temperature, pH levels, oxygen availability, and the types and concentrations of pollutants present.
