Industrial Wastewater Treatment Plant Testimonial

Dairy Wastewater Treatment with ProBiotic Scrubber® II

Brinjac Engineering, Inc. worked with a dairy facility in Pennsylvania to address several wastewater treatment challenges using BioLynceus® ProBiotic Scrubber® II (PBII).

The dairy was experiencing issues with:

  • Wastewater odors

  • Fats, oils, and grease (FOG)

  • Wet well maintenance

  • Sludge accumulation

  • Dairy process wastewater treatment

ProBiotic Scrubber® II was incorporated into the treatment program to support biological degradation of organic material and improve overall wastewater conditions.

Reducing FOG and Odors in the Wet Well

Before treatment, the facility’s wet well pump station had significant accumulations of grease and fats along with strong wastewater odors.

After approximately one year of applying ProBiotic Scrubber® II directly into the pump station, Brinjac Engineering reported a substantial improvement in conditions.

According to Stephen Zeller, the wet well that had previously been coated with grease was observed to be clean and free of significant grease accumulation.

Odor conditions also improved during the treatment period.

Supporting Dairy Wastewater During Construction

The dairy later began a construction project to install a new wastewater pretreatment process.

Construction continued for more than nine months, during which the existing digester was taken out of service.

As a result, the facility’s existing treatment tank had to temporarily manage the additional sludge solids that would normally have been handled by the digester.

This created a significant challenge for the wastewater treatment process.

Supporting Sludge Digestion in the Aeration Tank

BioLynceus® ProBiotic Scrubber® II was added to support biological degradation of sludge within the aerated treatment tank.

According to Zeller, the facility operated for more than nine months without requiring sludge wasting during the construction period.

The treatment process remained stable, and no significant wastewater odors were reported during this time.

The biological treatment program helped support:

  • Sludge digestion

  • Organic solids reduction

  • FOG degradation

  • Odor control

  • Aeration tank performance

  • Treatment stability during construction

Biological Treatment for Dairy Wastewater

Dairy wastewater can contain high concentrations of biodegradable organic material, including fats, oils, grease, proteins, and other process residues.

These materials can increase BOD, contribute to odors, and create additional solids-handling requirements.

BioLynceus® ProBiotic Scrubber® II was used at this facility to support biological treatment during both normal operation and an extended construction period.

“After one year of applying BioLynceus® ProBiotic Scrubber® II at the dairy into the pump station, the wet well is now clean and grease free.”
