How to Improve the Performance of Failing Lagoons Q&A

We hope you were able to attend our last free lagoon webinar: How to Improve the Performance of Failing Lagoons. If not, it’s available to watch at your convenience on our YouTube channel (linked below) or through our Lagooniversity portal.

Webinar attendees posed a bunch of great questions during the Q&A session. Since many are of general interest, we thought we’d share them along with webinar presenter Tom Daugherty’s answers.

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 in pond performance.” In this article, we’ll review the effects of cold temperatures on a lagoon and highlight methods of optimizing wastewater lagoon operations this winter.

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 video case study was shot with a 360° camera—watch it with VR goggles for an immersive experience, or simply use your finger or mouse to rotate the view.

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 what the ratio of total suspended solids to BOD5 in final effluent reveals about the cause of lagoon solids issues.

Lagoon Cyanobacteria: The Blue-Green Algae Blooms of Summer

lagoon cyanobacteria

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 rampant algal growth, or blooms. Cyanobacteria are classified by the EPA as harmful algal blooms, or HABs, because they cause eutrophication or dead zones and can even release toxins that are harmful or deadly to people and animals.

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 expensive and disruptive, so the longer a lagoon can go between dredgings, the better. In this article, we’ll discuss methods of lagoon sludge reduction in situ, without dredging.

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 be resolved quickly by improving oxygen transfer or adding more air. However, it’s important to diagnose what’s happening when air is going into the lagoon yet there’s insufficient DO to meet treatment requirements.

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 LDIB-TV, Patrick Hill gives the lowdown on duckweed. Watch the video and read below for highlights.
