Just Another Snake Oil?

by Heather Jennings, PE

For years, the wastewater industry has been plagued with products that meet only half the expectations of the users or make matters worse. I get it. I personally questioned the efficacy of Micro Carbon Technology® (MCT—the nutrient carrier for all our liquid nutrient and biostimulant products) when I started with Probiotic Solutions®. Because I was the Doubting Thomas of the group, I was assigned to conduct data analysis of projects and to work with our R&D group. My training is Chemical Engineering, so I was not looking for the easy answers. My customers deserve the best answers I can give them! [Read more…]

Microplex® JS Jump Starts Utah Summer Camp WWTF

by Heather Jennings, PE

If I had to choose a favorite of our microbial products it would have to be our Microplex® JS product. It is a two-part formulation of a live synergistic blend of natural, Class I bacteria, specifically chosen for their ability to rapidly degrade solids, fats, lipids, proteins, detergents, hydrocarbons, and other compounds. It’s actually magical in the sense that we can start a new activated sludge plant with it or help one recover rapidly when biomass is lost. I can put it in and know it works. What’s even better is that it’s a live culture: mix two 50 ml vials in 55 gallons of water and within hours you have 55 gallons of microbial product ready to apply. Does it save the world? No, but if you’d like a break from some of the biomass issues you’ve been dealing with it can at least save you an ulcer or two. [Read more…]

Up to 85% Solids Destruction Achieved Using BIO ENERGIZER®

By Heather Jennings, PE

The wastewater treatment facility operators at a city in Missouri wanted better digester performance. They needed a better settling sludge and a higher volume of decants, as well as more room to waste sludge within their existing digesters. The options to dispose of the digested sludge were becoming more and more scarce.

After trialing 3 products, they found BIO ENERGIZER® reduced their solids the best. Significant improvement in settling as well as a significant reduction in the total solids occurred in their digesters. They have achieved up to 85% volatile solids destruction using BIO ENERGIZER®. Another benefit that the City has gained is increased decant volumes. The City has doubled the number of decants by using BIO ENERGIZER® compared with other products previously used. This all results in lower hauling and handling costs. All it takes is a peristaltic pump and the product to get you similar savings! [Read more…]

Anaerobic Digester Saves 42% In Sludge Hauling

by Heather Jennings, PE

The case summary described below is an example of how our Bio Energizer® product helped reduce overall solids handling and improved supernatant clarity. It really doesn’t take much Bio Energizer® to reduce solids within your system when the microbial community is stimulated or “kicked into gear” to do their job. Typically, in anaerobic digestion we dose between 1–2 gallons/MGD. This system had 250,000 gpd and, after an initial dose of 2 gallons, they added 7 oz/day of the product for 60 days in their primary digester. The results? The volume of each decant was double the normal volume, and they had half the solids loading with an average of 0.21% solids. Continuously using the product over two years yielded a net savings of $1,024/ month! [Read more…]

The Water Break Podcast, Episode 8: Microscopy and DNA, A Match Made In Heaven

“Where we bridge the gap between water plant operators and engineers”

In Episode 8, Heather Jennings discusses DNA Analysis and Microscopy with Dr. Paul Campbell and Ryan Hennessy. Paul has extensive experience with microbial physiology, industrial microbiology, and fermentation and leads Aster Bio’s molecular biology and biochemistry work. Ryan is a microbiology and operations specialist at Midwest Contract Operations. Topics covered in the podcast include introduction and orientation to wastewater microbiology evaluation including Next Generation DNA Sequencing, qPCR, and microscopic evaluation; identifying and interpreting microorganisms and their roles in wastewater processing; and tracking microbiology trends in system operations.

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.

The Water Break Podcast, Episode #5: Lagoon Aeration

“Where we bridge the gap between water plant operators and engineers”

In this podcast episode, host Heather Jennings, PE, interviews Patrick Hill, a wastewater treatment lagoon specialist at Triplepoint Environmental. Patrick has presented on lagoon topics at conferences throughout the U.S. and at WEFTEC. He was named one of Water and Waste Digest’s young water professionals to watch in 2015. In this podcast, Heather and Patrick discuss lagoons, their technical considerations, and aeration options. And at the end of the podcast, in Wanda’s Water Tidbits, Heather describes an Australian effort to use an electrochemical method to clean up heavily polluted industrial wastewater.

Where Did the Water Go?

By Jared Alder, MS 

In England, it is estimated that around 700 million gallons of waterthe equivalent of 1,200 Olympicssize swimming poolsis lost every day to leaks in the country’s vast water system. Often the water just rises out to the pavement and runs down the roadUtilities spend countless hours and a great deal of money and other resources trying to locate the sources of leaks, often tearing up roads multiple times in this search. 

During large rainstorms, leaks can occur from the added amount of water that seeps into the system via the same openings where water exits from the system during dry times. During the recent Tropical Storm Cristobal in the Gulf Coast area of the United States, utilities reported sewage spills that occurred during and after the stormThe spills are a result of a complex underground sewer system that is not capable of handling modern weather events. Large rainfall events, such as tropical storms and hurricanes, can overwhelm aging infrastructureincluding old wastewater pipes, pump stations, and, in some cases, treatment facilities.  [Read more…]
