Ducks Walking on Water?

Bio Energizer® Reduces Sludge Over 40% at Utah Municipal WTP

The case study described below was a project that I worked on with a small-lagoon municipal system so overwhelmed with solids that state action was being taken. The ducks on the other side of the lagoon from me literally looked as though they were walking on the water surface! Honestly, that was a new one for me. We can help prevent solids buildup with little capital costs and time! The case study is below. [Read more…]

Up to 85% Solids Destruction Achieved Using BIO ENERGIZER®

By Heather Jennings, PE

The wastewater treatment facility operators at a city in Missouri wanted better digester performance. They needed a better settling sludge and a higher volume of decants, as well as more room to waste sludge within their existing digesters. The options to dispose of the digested sludge were becoming more and more scarce.

After trialing 3 products, they found BIO ENERGIZER® reduced their solids the best. Significant improvement in settling as well as a significant reduction in the total solids occurred in their digesters. They have achieved up to 85% volatile solids destruction using BIO ENERGIZER®. Another benefit that the City has gained is increased decant volumes. The City has doubled the number of decants by using BIO ENERGIZER® compared with other products previously used. This all results in lower hauling and handling costs. All it takes is a peristaltic pump and the product to get you similar savings! [Read more…]

Anaerobic Digester Saves 42% In Sludge Hauling

by Heather Jennings, PE

The case summary described below is an example of how our Bio Energizer® product helped reduce overall solids handling and improved supernatant clarity. It really doesn’t take much Bio Energizer® to reduce solids within your system when the microbial community is stimulated or “kicked into gear” to do their job. Typically, in anaerobic digestion we dose between 1–2 gallons/MGD. This system had 250,000 gpd and, after an initial dose of 2 gallons, they added 7 oz/day of the product for 60 days in their primary digester. The results? The volume of each decant was double the normal volume, and they had half the solids loading with an average of 0.21% solids. Continuously using the product over two years yielded a net savings of $1,024/ month! [Read more…]

Bio Energizer® Cuts Sludge Hauling Costs for Potato Wastewater Treatment Plant

Potato Wastewater TreatmentA 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 (SBR). He couldn’t decant more than 2–3 feet under the excess load.

Bio Energizer® Reduces Cost and Turbidity in Paperboard Lagoons

BOD & COD Discharges in Paperboard Lagoon

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 pounds of fiber per day into the Ohio river.

Bio Energizer® Improves SVI by 50% at Citrus Plant Wastewater Treatment

citrus production

A citrus plant struggled with poor settling in the clarifier of its wastewater treatment, which caused the sludge blanket to remain high. Even at a low flow rate of 1.2 million gallons per day (MGD), the high sludge blanked allowed less than 18” of free board. The slightest flow increase caused solids to carry over the weir with the effluent. Since the citrus plant frequently produced wastewater flows 1.5 to 2.5 MGD, the wastewater treatment plant continued to suffer from solids washout and clarifier effluent total suspended solids (TSS) excursions. The citrus plant wastewater treatment was a 6 million gallon per day (MGD) traditional aeration system with secondary clarification.

Industrial Wastewater Treatment for Corn Processing Plant

Bio Energizer Treatment for Corn Processing Plant

Within a few months of operation, a lagoon and spray field system at a corn processing plant in Indiana began giving off offensive odors. Chemical oxygen demand (COD) levels in the anaerobic and aerobic lagoons climbed to 8,000 mg/L and 4,000 mg/L respectively. The pH in the anaerobic lagoon was dropping dangerously low for methane production. Attempts to resolve the issues with bacteria, odor masking products, and lime were unsuccessful and short-term at best. Lime settled to the bottom of the lagoons, temporarily raising pH and reducing odors. The odor soon became unmanageable and an annoyance to neighbors.

Bio Energizer, Micatrol & Bio Feed Reduce COD and Stabilize Wastewater Treatment for Plastic Producer

chartA plastic manufacturer in Taiwan needed a new process to efficiently treat elevated incoming chemical oxygen demand (COD) to comply with stringent EPA regulations for effluent discharge. The plant is an activated sludge treatment system with an influent of approximately 2,000 cubic meters per day (CMD) which is equivalent to approximately 530,000 gallons per day (GPD). The plant was unable to bring the plant into compliance using alternative technologies.

BIO ENERGIZER® Reduces Sludge at Sugar Refinery Wastewater Treatment Lagoons

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 issues. The sugar refinery had a history of periodically being unable to meet its National Pollutant Discharge Elimination System (NPDES) permitting requirements. Continue reading

Rural Colorado Town Uses BIO ENERGIZER® to Reduce Wastewater Lagoon Sludge and Save Money

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
