The Water Break Podcast, Episode 16: The Environmental Laboratory, Tips and Tricks for Sampling

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

In Episode 16, Heather Jennings, PE, discusses Environmental Laboratory Sampling Tips & Tricks with Marci Payne, Sales and Marketing Director at Legend Technical Services of Arizona, Inc. In this podcast, Ms. Payne provides a general overview of best practices for collecting water and wastewater samples for testing at an environmental laboratory.

Let’s Talk Nutrients for a Minute

by Heather Jennings, PE

Generally, in the wastewater industry we talk about 100 mg/L BOD to 5 mg/L Nitrogen to 1 mg/L Phosphorus. The values for nitrogen and phosphorus can be higher or lower than this, but it’s the average number that many wastewater system designs are built around.

If you look a little further, there is another formula used to describe the typical biomass of cells, C12H87O23N12P. This just isn’t all that is needed, though, to build a healthy biomass. Just like how my kids can’t grow healthy on pizza and their favorite blue box of mac and cheese, microbes need additional inorganic nutrients such as potassium, calcium, iron, and chlorine. They also need micronutrients such as molybdenum, cobalt, nickel, and others. This is where many wastewater systems are typically deficient: the micronutrients. What wastewater treatment facility operators often don’t realize is that you can have all the carbon, nitrogen, and phosphorus in the world, but without the inorganic and micronutrients you may never be able to truly optimize your system!

The more diversified your influent, the better off you are, but you can still have a system always on the edge of running out. Add chronic toxicity or a mild upset, and you can lose the whole biomass overnight. Our Probiotic Solutions® product, Bio Genesis®, uses a carbon carrier to deliver macro- and micronutrients to the cells. The added bonus is that the carbon carrier we call Micro Carbon Technology® is itself a biostimulant—think energy drink for the microbes—that helps them reduce solids and organics more efficiently than previously possible.

Use of Biostimulants for Upset Recovery in Paper Mill Wastewater Systems

By Heather Jennings, PE

Two specific Probiotic Solutions® liquid bioremediation products were used at a large-scale paper mill in China to address system upsets caused by hydraulic loading from new upstream processes.

The products involved are 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 our proprietary Micro Carbon Technology® (MCT) to deliver readily bioavailable nutrients to microorganisms. [Read more…]

Your Wastewater System Runs Smoothly, Until It Doesn’t!

By Heather Jennings, PE

The first thing I usually hear from operators is that they don’t have any problems! Everything runs perfectly, all the time, until it doesn’t. Then the heartburn, extra hours, and long days begin. The only other thing as sure as death and taxes for a wastewater system is that it will one day have a system upset. It might not be often, but when it does, let’s talk about what to look at first.

The Water Break Podcast, Episode 2: Enhanced Biological Phosphorus Removal in Wastewater

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

In this podcast episode, host Heather Jennings, PE, interviews wastewater microbiologist and certified operator Toni Glymph-Martin on the topic of Enhanced Biological Phosphorus Removal in Wastewater. Toni has more than 40 years of wastewater experience and is the author of several wastewater microbiology textbooks.

The Water Break Podcast, Episode 1: Wastewater Nitrification and Denitrification

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

In our first podcast episode, host Heather Jennings, PE, discusses the wastewater nitrification-denitrification cycle with two guests, John Souza and Diego Lopez. John Souza is Utilities Manager for the City of Lemoore, California. He is also a Grade T-4 Water Operator, Grade 3 Wastewater Operator, and D-3 Distribution Operator. Diego Lopez, also with the City of Lemoore, is a Grade 2 Wastewater Operator working toward his Grade 3 exam.

Nitrification-denitrification is the great “teeter-totter” of wastewater treatment. Nitrogen is one of the most abundant elements on earth, so why do we spend millions of dollars removing it from water? And how do we do it?
