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 […]

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 […]

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 […]

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 how Triplepoint’s patented NitrOx® Process improves on the lagoon MBBR by adding a heating element […]

Land Application of Lagoon Effluent: Pros and Cons

Land application is the most common disposal method for treated wastewater in the U.S., and is the preferred method in many states. Land applying effluent can reduce demand for fresh water, provide nutrients to soil, and keep potential contaminants out of waterways. For lagoons, it may also be a way to avoid having to meet […]

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 […]
