For our May "Water Break" podcast we'd like to test the experience of 3 panelists who collectively have 100 years of experience between them. Please send me the trickiest wastewater issues you've dealt with or are currently dealing with! I personally can’t wait to hear our panelists' responses! Send your questions to Heather@bhn.us by 5
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
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,
By Heather Jennings, PE As winter loses its grip on us and we move toward spring, it’s finally time to start monitoring lagoons for seasonal turnover and stricter permit requirements. It’s also a great time to start bioremediation of your lagoon organic sludge! With warmer weather it is easy to capitalize on those microorganisms that
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
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
by Heather Jennings, PS In this study, a one-year bioremediation plan featuring Bio Energizer® 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. Bio Energizer® was added via peristaltic pump to
by Heather Jennings, PE Bio Energizer® Reduces Sludge Over 40% at Utah Municipal WTP The case study described below was a project that I worked on with a small-lagoon municipal system so overwhelmed with solids that state action was being taken. The ducks on the other side of the lagoon from me literally looked as
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
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
