PS Article Published in Tri-State Seminar Proceedings

An article by Heather Jennings, PE, Director of Probiotic Solutions®, has been published in Tri-State Seminars Magazine, the proceedings of the 36th Annual Tri-State Seminar held August 9–12, 2021, in Las Vegas, Nev. Ms. Jennings was a featured presenter at the seminar, which provides training and certification classes to educate water professionals from Arizona, California, and Nevada.

In her presentation and the resulting published article, titled “Lagoons, Under the Surface,” Ms. Jennings discussed the results of an in-depth investigation of bioremediation and biological factors involved in reducing sludge at a municipal wastewater treatment facility lagoon system.

A one-year bioremediation plan was implemented for a municipal wastewater treatment facility with 2 primary lagoons in which sludge depths had reached 5–7 feet. The lagoons were at risk of upset and wastewater processing capacity was reduced. Sludge levels were reported for baseline and quarterly sludge judging, supplemented with ATP and DNA analyses of the microorganism biomass. The results of the ATP and DNA analyses pointed out the often-misunderstood fact that wastewater treatment facility lagoon sludge is not inert: it is the most biologically active layer of the water column and can be efficiently controlled and reduced through proper bioremediation interventions. Sludge depth was biologically reduced by an average of 45%. This represented 17,800 dry tons of sludge that did not need to be mechanically removed and hauled to a disposal location, a potential savings of over $6 million.

White Paper: Lagoons—Under the Surface

An In-Depth Investigation of Bioremediation and Biological Factors Involved in Reducing Sludge at a Municipal Wastewater Treatment Facility Lagoon System

Heather Jennings, PE, Sr. Project Engineer, Probiotic Solutions®

Abstract

In this study, the operators of a municipal wastewater treatment facility with 4 lagoons had determined that their 2 primary lagoons—10-foot-deep, with 25-million-gallon holding capacity each—had reached sludge depths of 5–7 feet, putting the lagoons at risk of upset and seriously impacting the facility’s wastewater processing capacity.

How to Reduce SVI and Foam in Activated Sludge Plants

In this short video, Shawn Whitmer, PE, discusses how foam and settling caused by filamentous bacteria can create problems for municipal activated sludge wastewater treatment plants. Our Probiotic Solutions® liquid stimulant product, Bio Genesis®, can help facilities take a bioremediation approach to improve treatment performance; reduce foam, SVI, sludge, and FOG; and decrease energy costs.

Use of Biostimulants & Buffers for Upset Recovery at Paper Mill Wastewater System

Industrial Water & Wastes Digest has published a Probiotic Solutions® article, “Use of Biostimulants & Buffers for Upset Recovery at Paper Mill Wastewater System.”

Two specific Probiotic Solutions liquid bioremediation products were used to address process upsets at a paper mill in China. The products involved were 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 the proprietary Micro Carbon Technology (MCT), a process that converts a soft, humic material into extremely small oxygen-rich carbon molecules. The MCT process results in a carbon source that is an ultra-efficient carrier—due to the micro-carbon molecule’s low molecular weight, greater specific surface area and higher cation exchange capacity—to deliver readily bioavailable nutrients to microorganisms.

In this trial, BE and MT were applied to the biological treatment system of a large-scale paper mill to manage the hydraulic loading from new upstream processes that led to a system upset.
