Wastewater Lagoon Operations: Preparing for Cold Winter Weather
Water temperature affects virtually every aspect of wastewater lagoon performance. As lagoon expert Steve Harris states in his operators’ guide, Wastewater Lagoon Troubleshooting, “Water temperature is a reliable predictor of water quality and can aid the operator in preparing for changes … Continue reading
Aerated Lagoon Upgrade: A 360° VR Video Case Study
An aerated lagoon upgrade provides many benefits: it improves treatment, saves on energy cost, and reduces operations and maintenance demands. Our latest video case study of Pacific, Missouri, highlights the benefits of upgrading a lagoon facility with Triplepoint aerators. This … Continue reading
Lagoon Solids: Using the TSS to BOD5 Ratio to Diagnose Treatment Problems
Biological Oxygen Demand (BOD) and Total Suspended Solids, or TSS, are standard testing parameters for wastewater lagoons. The ratio between the two numbers can provide valuable insight into the source of the TSS. In this article, we’ll take a look at … Continue reading
