Lagoon Water Fleas as Indicator Organisms: About Daphnia

What are Lagoon Water Fleas? https://youtu.be/9IS_t99jdRs Daphnia pulex, although often called water fleas, are actually freshwater crustaceans closely related to shrimp. They take their nickname from the way they propel themselves through the water, which resembles the hop of a flea. Daphnia, the most common microscopic crustacean, can be visible to the naked eye, with […]

Lagoon Algae Prevention and Treatment: Strategies and Methods

Summertime is boom time for algae due to the warm temperatures, abundant sunlight, and high nutrient loads. Excessive algal blooms in wastewater lagoons cause treatment deficiencies, so it’s a good time to look at some of the options for lagoon algae prevention and treatment. Why is lagoon algae a problem? Algal blooms in a wastewater lagoon, […]

Summer Ammonia Removal: Optimizing Warm-Weather Nitrification

Summer ammonia removal via nitrification is less of a challenge for lagoons than cold weather ammonia removal, as nitrifying bacteria are temperature sensitive and thrive in warmer water. The interplay between algae and bacteria, dissolved oxygen, pH, and temperature determines the pathway and rate of nitrification. Watch our video, 6 Key Factors for Nitrification, then […]

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 rampant algal growth, or blooms. Cyanobacteria are classified by the EPA as harmful algal blooms, or […]

The Hidden Costs of Replacing a Lagoon with a Mechanical Plant

When confronted with new effluent limits, many municipalities feel their only option is to scrap their otherwise adequate lagoon system and replace it with a mechanical plant, such as an activated sludge, SBR, or MBBR treatment process. There’s a better option: A lagoon can be upgraded to remove ammonia, total nitrogen, and phosphorus; treat BOD […]

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. That’s because, like algae and sludge, duckweed is just one of those things that comes with the territory. In this two minute video from our Lagoons Do It Better channel on You Tube, Patrick Hill gives the lowdown […]

Spring Lagoon Odors: Can Lagoon Circulators Prevent Them?

It’s spring! The snow is melting, the birds are chirping, and all the solids that settled to the bottom of the wastewater lagoon over the winter are getting dislodged, releasing sludge and gases that create spring lagoon odors. For many municipalities, the spring and fall lagoon turnovers with their accompanying foul odors are just signs […]

Summer Lagoon Nitrification: Optimizing Warm-Weather Ammonia Removal

Nitrification is the most common way to biologically remove ammonia in wastewater lagoons. In this process, ammonia treatment occurs via bacteria already present in the water. These bacteria break down the ammonia and eventually promote the release of nitrogen gas into the atmosphere. The end result is that your wastewater lagoon ammonia is nitrified, resulting […]
