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
Lagoon MBBR: Moving Bed Biofilm Reactors for Ammonia Removal
The lagoon MBBR, or moving bed biofilm reactor, is a proven technology for the removal of lagoon ammonia through biological nitrification. In this article, we’ll describe MBBR technology and how it’s been adapted for lagoon ammonia treatment. Then, we’ll explain … Continue reading
