Problem  A small town in Utah (pop. 1,800) had a municipal wastewater system with a flow rate of 192,000 gallons per day. The system included a series of four lagoons that tapered to a depth of 6 feet, although at this time only Ponds 1 and 2 were being evaluated for treatment as they were

Abstract  Bio Energizer® is frequently used to facilitate bioremediation of wastewater. A study was conducted by an independent laboratory to measure possible negative effects Bio Energizer® might have on a freshwater test species (rainbow trout).   Using EPA-approved methodology to evaluate Bio Energizer®, the lab administered the product at 10 ppm to a test tank and

Problem  The existing wastewater treatment system uses 600 kg/day of diammonium phosphate (DAP) to provide the needed phosphorus concentration to maintain a healthy microbial population to treat wastewater. These microorganisms break down the organic matter being discharged from the paper processing facility. Without the correct concentration of available phosphorus, the microorganisms are unable to grow

Problem  A municipal wastewater treatment facility in Idaho uses a small, activated sludge system to treat 35,000 gallons per day (gpd); waste activated sludge (WAS) is removed from the system approximately every 2 to 3 weeks. The system frequently experienced intermittent foaming and settling issues, as well as seasonal impact from grease relating to the

Summary 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. Sludge levels were measured at baseline and quarterly. Sludge depth was

Summary  In this study, a one-year bioremediation plan was implemented for a municipal wastewater treatment facility with 2 primary lagoons that were at risk of upset and in which wastewater processing capacity was reduced due to an increased sludge layer. Specific changes in strata microbial life were tracked through ATP and DNA analysis at quarterly
