Problem A paper mill wastewater facility was treating 940 tons of paper bags, recycled linerboard, and corrugating medium, daily. The mill was interested in improving wastewater operating efficiency and lowering operating expenses over their standard polymer usage. The plant was experiencing filamentous bacteria, solids, and bulking issues in the final clarifier. It was discharging 4,000

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

Problem  A municipal wastewater treatment facility in Arizona uses an activated sludge system with 4 oxidation ditches to treat approximately 9 million gallons per day. The system frequently experiences intermittent foaming and settling issues. The operator was looking for a solution to the foaming and settling issues that would also provide operational stability throughout the

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

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

Problem  A small town in New Mexico (pop. 1,300) had a municipal wastewater system with a flow rate of 50,000 gallons per day. The system included a series of three lagoons that tapered to a depth of 13 feet. Pond 1 had an average sludge depth of 1.9 feet, Pond 2 averaged 3.5 feet, and
