Use of Biostimulants and Buffers for Upset Recovery in Paper Mill Wastewater Systems

By Heather Jennings, PE

Industrial pulp and paper wastewater is considered one of the more challenging waters to treat using biological methods, which depend on microbial activity to effectively remediate the wastewater.

Wastewater treatment systems are often influenced/impacted by increased hydraulic and/or COD (chemical oxygen demand) loading as mills add new chemicals or otherwise modify mill operations. These events oftentimes inhibit the wastewater microbial activity, causing “upsets” and, potentially, discharge-limit violations. However, providing the necessary biostimulants and buffers to the microbial system—as we describe in this case study from a paper mill in China—can significantly improve system-upset recovery time and overall operational stability.

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.
