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

Lagoon Cyanobacteria: The Blue-Green Algae Blooms of Summer
Lagoon cyanobacteria can cause a thick scum on the surface of the water and nasty odors. During the summer, the combination of sunlight, warm water temperatures, high nutrient loads, and predation by higher life forms like Daphnia and rotifers can lead to … Continue reading
Lagoon Sludge Reduction In Situ: Methods of Removing Sludge in Place
One of the benefits of lagoons for wastewater treatment is their built-in sludge storage, which reduces the need for sludge handling. However, every lagoon will eventually require dredging to remove nonvolatile solids like grit. The mechanical removal of sludge is … Continue reading
Wastewater Pond DO: Where Did the Dissolved Oxygen Go?
A wastewater pond requires sufficient Dissolved Oxygen (DO) to satisfy Biological Oxygen Demand (BOD) and Nitrogenous Biochemical Oxygen Demand (NBOD). Without DO, a pond can experience odors and high effluent BOD and can even go septic. Often DO problems can … Continue reading
Lagoon Lemna: Pros and Cons of Duckweed in a Wastewater Pond
Lagoon lemna, or duckweed, has been a popular topic on our Lagoons Do It Better Facebook group lately. That’s because, like algae and sludge, duckweed is just one of those things that comes with the territory. In our latest episode of … Continue reading
Wastewater Treatment Pond Odor Control for Spring Turnover
Unmixed wastewater treatment ponds can experience turnover in the spring, so it’s the time of the year when operators (and local residents) are most concerned about unpleasant wastewater odors. Although spring lagoon turnover and its accompanying odors may be normal … Continue reading
Triplepoint’s NitrOx Lagoon MBBR: A Video Case Study
A lagoon MBBR is a tertiary treatment process added to a lagoon system for the purpose of ammonia removal through biological nitrification. Our previous blog post, Lagoon MBBR: Moving Bed Biofilm Reactors for Ammonia Removal, explains the process in detail. … Continue reading
Lagoon Aeration System Design: Individual Air Lines vs. Fixed or Floating Laterals
A lagoon aeration system will require some method to convey air from the onshore blower to each aeration unit. Two distribution methods are typical: individual air lines or lagoon laterals, either submerged and fixed to the bottom; or floating on … Continue reading
