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
Today on Episode 9 we’re talking about Growing Premium Corn with Huma Gro® Products. Our guests include Mr. Lyndon Smith, President and CEO of Bio Huma Netics, Inc.—the maker of Huma Gro®, Fertilgold® Organics, Mesa Verde Humates, and several other product lines—and Mr. Jason Garcia, Florida Sales Manager and Agronomist for Bio Huma Netics,
By Jared Alder, MS In England, it is estimated that around 700 million gallons of water—the equivalent of 1,200 Olympics-size swimming pools—is 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 road. Utilities 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
By Heather Jennings, PE When I worked with engineering firms, there were a lot of water master plans being developed. Many of them were updates, as the plans had been around for 5–10 years and needed revision. Some master plans evaluated water and wastewater systems from scratch. All of these were interesting to me due
By Heather Jennings, PE When I first came into the water field in the 2000s, the general rule of Chemical Oxygen Demand to Biochemical Oxygen Demand (or COD to BOD5) was 2:1. That was pretty much all you needed to know in order to understand whether something could be treated chemically, physically, or biologically. Now, the wastewater industry has moved toward COD instead of BOD5. The reason that COD is
By Heather Jennings, PE Of all the wastewater lagoon systems I have been to, I’ve never met the same lagoon twice! Many consider lagoons old tech, but they can be very reliable and more stable treatment systems than many of the more sophisticated systems out there. Lagoons, like any wastewater system, should not be left
By Jared Alder, MS The treatment of wastewater is a delicate balance of chemical, biological, and mechanical processes. Treatment operators need to find a happy medium to provide high-quality treatment, while staying within budgets and all the while ensuring they meet environmental compliance. Operators are expected to deal with a constantly varying treatment system, such
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
By Jared Alder, MS There has been a big focus in domestic wastewater on the removal of phosphorus and the potential for excess phosphorus to cause eutrophication in receiving water. Treatment facilities of all different shapes and sizes with inadequate phosphorus treatment technologies have the potential for excess phosphorus release. The removal of phosphorus from
By Heather Jennings, PE Phosphorus is one of the most abundant elements on earth. It’s essential for adenosine triphosphate (ATP), the energy carrier life is built on. But in excess in our lakes and ponds, we see large algal growths occurring. Many times, these algal blooms suffocate the surrounding aquatic life and or produce toxins
