Use of Biostimulants for Upset Recovery in Paper Mill Wastewater Systems

By Heather Jennings, PE

Two specific Probiotic Solutions® liquid bioremediation products were used at a large-scale paper mill in China to address system upsets caused by hydraulic loading from new upstream processes.

The products involved are Bio Energizer® (BE)—a scientific formulation of organic acids, buffers, natural biological stimulants, micronutrients, and energy systems—and Micatrol® (MT), a specialized product that uses organic acid as a substrate to buffer wastewater microbial life. Both BE and MT are complexed with our proprietary Micro Carbon Technology® (MCT) to deliver readily bioavailable nutrients to microorganisms. [Read more…]

Are You Using Wastewater Bioindicators?

By Jael Batty

Water quality can be evaluated quickly, efficiently, and cost-effectively through the use of bioindicators. The presence and activities of microorganisms can indicate changes in system operations and point to the source and magnitude of an issue.1

Protozoa

Approximately 4% of the microorganisms in wastewater are protozoa, which are single-celled aerobic microorganisms. Protozoa improve effluent clarity by digesting suspended particles and bacteria. Read more about wastewater bioindicators

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.
