The wastewater treatment plant superintendent for a rural Colorado town of about 500 people noticed that the plant’s three wastewater lagoons were filling with sludge, but he was dealing with budget constraints. The town’s population fluctuates throughout the year, and the varied loading was affecting system performance. Continue reading
Location: Louisiana A large sugar refinery struggled with elevated BOD and COD values in its wastewater treatment lagoons due to the sugar refinery process. The lagoon wastewater system capacity was 25 million gallons with an influent of 1.25 million gallons per day. The wastewater system also suffered from accumulating sludge as well as significant odor
Bioremediation can improve the activity and reproduction of wastewater microbiology. The following case studies used bioremediation to improve wastewater treatment conditions and operating costs. Continue reading.
Plant Manaer Geraldo O.: "It's the silver bullet we've been looking for all along." Plant Operator Steve W.: "We tried everything to solve the (odor) problem....We've been tickled to death with the product." Plant Operator Ken R.: "It definitely works. Bio Energizer allows us to function more efficiently."
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.
A wastewater treatment plant in Pennsylvania was experiencing process control problems when new potato waste stream flows increased by 26%. The additional load was causing filamentous issues in the sequencing batch reactor (SBR), settlability problems, and increased sludge hauling costs. The engineer was unable to maintain the 8-foot decant level in the sequencing batch reactor
