Lagoon Nitrogen and Lagoon Ammonia…What’s the Difference?

Whether your facility has a lagoon nitrogen (TN, TKN, or TIN) or ammonia (NH3) effluent limit depends on your local environmental regulatory body, your discharge parameters, and if the watershed you discharge to is impaired. So far, most lagoon permits with an ammonia or nitrogen limit restrict only unionized ammonia (NH3), although some (and going […]
NitrOx Lagoon Nitrification Reactor Approved in Iowa

Due to the success of the pilot, the Iowa DNR has approved a full installation of Triplepoint’s NitrOx® Process for lagoon nitrification in De Soto. Like many Iowa municipalities, the City of De Soto required an upgrade to their lagoon system to meet more stringent ammonia effluent requirements. In this article, we’ll review the conditions […]
Removing Lagoon Ammonia: 6 Key Factors for Nitrification

Strategies for removing lagoon ammonia have become a hot topic over the past few years. Many state environmental agencies have been introducing new ammonia limits for wastewater facilities, including lagoons. This is a problem because most wastewater lagoon systems were not originally designed for ammonia treatment; as a result, most will require some kind of […]
Wastewater Lagoon Nutrients: The TL;DR of TMDL

In its effort to protect the health and safety of America’s waterways, the EPA and state environmental agencies have focused on limiting the amount of pollutants that can be discharged into them. In previous articles, we’ve covered pathogens and wastewater lagoon nutrients ammonia and phosphorus; in this article, we’ll discuss Total Maximum Daily Loads (TMDL), […]
Say Hello to My Little Friend: The Tardigrade

The tardigrade, a ubiquitous creature familiar to wastewater professionals, is enjoying a moment in the spotlight. New York’s American Museum of Natural History is showcasing them as part of the exhibition Life at The Limits: Stories of Amazing Species. The BBC calls them “the toughest animals on Earth,” citing their successful round trip to outer space, attached […]
Sources & Treatment of Lagoon Ammonia

Sources of ammonia and nitrogen in lagoon effluent Lagoon ammonia levels have become a concern for many municipalities, who must find ways to comply with the EPA’s new effluent limits. But where does ammonia come from? There are multiple sources of nitrogen in wastewater lagoons: Human urea Industrial wastewater, especially from mining, crude oil processing, […]
Missouri Lagoon Ammonia: Dealing with Changing Regulations

Missouri’s new Lagoon Ammonia effluent permits, adopted to reflect the U.S. Environmental Protection Agency’s new water quality criteria, are posing a challenge for wastewater lagoon systems, which were not originally designed for cold weather lagoon ammonia removal. These new Missouri lagoon ammonia regulations are especially burdensome for smaller municipalities, who may fear significant capital expense […]
Evaluating 4 Lagoon Ammonia Treatment Solutions

Evaluating 4 Lagoon Ammonia Treatment Solutions Lagoon Ammonia Treatment seems to be constantly topping the agenda of wastewater lagoons these days. This is primarily due to new lagoon ammonia and, in some cases, nitrogen limits that are being placed on wastewater lagoons. The lagoon nitrification process is the most common form of biological lagoon ammonia/nitrogen […]
