Webinar Video: Lagoons Under the Surface

Webinar video highlights key findings—including $6M in savings—from a year-long bioremediation program for lagoon sludge reduction at a municipal wastewater treatment plant.

In this 31-minute video, Heather Jennings, PE, Director of Probiotic Solutions®, and Diego Lopez, Chief Plant Operator for the City of Lemoore, Calif., Wastewater Treatment Plant discuss highlights from the year-long study of a bioremediation program (using Bio Energizer®) for lagoon sludge reduction at a municipal wastewater treatment plant.

In the 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.

A bioremediation plan was implemented that included the use of a biostimulant to support microbial reduction of the organic solids in the system. Sludge judging was performed for the 2 primary lagoons at baseline and at quarterly intervals over a one-year period to measure the impact of the bioremediation plan on sludge reduction.

The results of 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

At the end of the one-year bioremediation plan, sludge depth for the 2 lagoons had been reduced by an average of 45%, with sludge depth at some sample points completely reduced to zero. 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 to the treatment facility of over $6 million.

PS and RWAAz Host PFAS Workshop

Probiotic Solutions®, along with the Rural Water Association of Arizona, conducted a workshop today on Per- and Polyfluoroalkyl Substances (PFAS) at Probiotic Solutions/Bio Huma Netics headquarters in Gilbert, Arizona. The workshop, titled “PFAS: The Phantom Menace,” featured presentations by Heather Jennings, PE, Director of Probiotic Solutions, and Marci Payne, Sales and Marketing Manager at Legend Technical Services of Arizona.

This was the first in a series of PFAS workshops that Heather will also be presenting for rural water associations in New Mexico and Utah. More information about PFAS can be found on our recent Water Break podcast at https://probiotic.com/2021/06/the-water-break-podcast-episode-15-pfas-what-are-they-and-why-do-i-care/.

The Water Break Podcast, Episode 15: PFAS—What Are They and Why Do I Care?

“Where We Bridge the Gap Between Water Plant Operators and Engineers”

In Episode 15, Heather Jennings, PE, leads a panel of 3 guests on a discussion of PFAS (Per- and Polyfluoroalkyl Substances) in the environment, drinking water, and wastewater. The panel includes Marci Payne, Sales and Marketing Director at Legend Technical Services of Arizona, Inc.; Cathy Swanson, West Regional Sales Manager and Groundwater Remediation Specialist at Purolite; and Dr. Rosa Gwinn, Global PFAS Technical Leader at AECOM. Heather and the panel discuss PFAS in terms of what they are, how they impact us, how we test for them, and issues related to removing them from the environment. They also discuss current regulatory requirements and what our level of concern should be in terms of addressing them in our industry.

Video: Earth Day, 2021

Over 50 years ago, on April 22, 1970, 20 million Americans took to the streets to protest environmental destruction and to celebrate the wonders of Planet Earth. The basic message was that we had to find new ways to live our lives, raise our food, and conduct our businesses that were environmentally friendly and sustainable—that would not waste resources or pollute the air, the water, or the soil.

It’s ALIVE!

by Heather Jennings, PE

. . . the lagoon sludge layer, that is. I’ve seen many lagoons full of sludge, and the general attitude I find in the water industry is that the sludge layer is inert and really can only be mechanically dredged. To a certain point, that is correct: sand, soil, grit, plastics—basically inorganics—do need to be mechanically dredged. The organics, on the other hand, don’t, and they are easily removed with bioremediation. Continue Reading
