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…]
In Episode 7, Heather Jennings discusses Wastewater Anaerobic Digesters with Kay Curtin. Kay is an Advanced Wastewater Operator in Wisconsin and a Level A Wastewater Operator in Minnesota, with 45+ years’ experience in wastewater. She is currently working with the Wisconsin Rural Water Association as a trainer/technician for Western Wisconsin and has her own consulting business, Curtin Consulting, LLC. Topics covered in the podcast include anaerobic digester pros and cons, bacteria used, nutritional requirements, key operating parameters, main causes of failures, and typical operating issues.

In this podcast episode, host Heather Jennings, PE, interviews Fred Black and Ray Ramos of the New Mexico Rural Water Association on the topic of Troubleshooting Water and Wastewater Systems. Fred and Ray troubleshoot water and wastewater systems in the state of New Mexico, and together they have more than 50 years of experience in the water/wastewater industry.
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 as from climate changes, human usage patterns, and more. With all of the possible changes, budget constraints, and regulator requirements, finding a balance can be quite challenging.
