Lagoon Sludge Reduction with ProBiotic Scrubber® I

Stephen C. Morris, Environmental Specialist with Giant Refinery Company, initially had reservations about whether a biological treatment program could significantly reduce accumulated sludge in the facility’s wastewater lagoons.

After implementing BioLynceus® ProBiotic Scrubber® I, the facility observed measurable changes in lagoon sludge depth and consistency.

Two Feet of Sludge Reduction After One Season

After one treatment season, Morris reported an approximately 2-foot reduction in accumulated sludge.

An additional 2 feet of sludge had softened, indicating further changes in the condition of the remaining solids.

These results exceeded the facility’s initial expectations for biological sludge management.

Continued Improvement During the Second Year

The facility continued using ProBiotic Scrubber® I for another year.

According to Morris, the second year of treatment produced additional improvements that exceeded the expectations of facility personnel.

The biological treatment program helped address a sludge-management problem that otherwise could have required more extensive and costly mechanical removal.

Potential Savings in Lagoon Sludge Management

Reducing accumulated lagoon sludge can help facilities:

• Recover treatment and holding capacity

• Delay mechanical dredging

• Reduce sludge handling requirements

• Lower hauling and disposal costs

• Improve long-term lagoon maintenance

Morris reported that the biological treatment program resulted in significant cost savings compared with the potential expense of addressing the accumulated sludge through conventional methods.

“After one season of treatment using ProBiotic Scrubber® I, I was very surprised to find an actual reduction of two feet of sludge and an additional softening of two feet.”

Continuing Biological Lagoon Treatment

Based on the results observed at the facility, Morris recommended ProBiotic Scrubber® I for other wastewater systems facing similar lagoon sludge challenges.

“The results achieved at this facility far exceeded any of our expectations. I would highly recommend ProBiotic Scrubber® I to anyone who has a need similar to the one at our facility.”

The results described above reflect observations from this specific wastewater lagoon application. Performance may vary depending on sludge composition, lagoon design, temperature, organic loading, treatment duration, and operating conditions.
