BIO ENERGIZER® Reduces Sludge 45% In One Year, Saves Municipal Plant $6 M In Dredging Costs

by Heather Jennings, PS

In this study, a one-year bioremediation plan featuring Bio Energizer® was implemented for a municipal wastewater treatment facility with 2 primary lagoons in which sludge depths had reached 5–7 feet. The lagoons were at risk of upset and wastewater processing capacity was reduced. 

Bio Energizer® was added via peristaltic pump to the lagoon inlets. Initially the dose applied was 7 ppm (7 gallons of product to 1,000,000 gallons of influent, assuming a typical Biochemical Oxygen Demand [BOD5] of 240 mg/L) and was eventually decreased 10 months later to 5 ppm. A maintenance dose of 3 ppm was established 2 months later.

Sludge levels were measured at baseline and quarterly. Sludge depth was biologically reduced by an average of 45%. This represented 17,810 dry tons of sludge that did not need to be mechanically removed and hauled to a disposal location, a potential savings of $6 million. When compared with product cost, and it was found that the facility product investment was 5.8% of the potential dredging costs.
