Ammonia Removal From Wastewater Lagoons

Ammonia

Bacteria that exists naturally in most bodies of water is capable of achieving some degree of nitrification and denitrification. Unfortunately, suspended growth bacteria is not effective enough for wastewater treatment in the face of the ever increasing regulations imposed on treatment facilities. Large mechanical plants are able to achieve effective nitrification and denitrification in expensive processes such as MBBR’s. Until recently, smaller treatment facilities that rely on lagoons haven’t had an effective alternative for improving the nitrification and denitrification in their ponds. WCS developed the Bio-Domes specifically for the small wastewater treatment facilities. The bio-film that grows in the Bio-Domes creates a robust colony of bacteria capable of achieving treatment levels that are comparable to some mechanical systems.

Below are a few examples of the Bio-Dome performance in removing ammonia and reducing total nitrogen concentrations. More information is available upon request.

Beta Trial – Nitrification & Denitrification Results

The data below was developed during the development of the Bio-Domes in cooperation with a local wastewater treatment facility. They provided WCS with a stream of wastewater that we ran through a container filled with bio-domes. The gray boxes indicate when the air was turned off. As you can see, while the air is on, the ammonia is consumed and turned into nitrate. As soon as the air is cycled off, the nitrate is converted into nitrogen gas and the concentration decreases. Bio-domes are capable of performing effective nitrification & denitrification.

Onsite Cold Weather Nitrification Results

The data below was developed as part of an on-site study for one of our customers. A few Bio-Domes were installed in a temporary pond adjacent to the larger lagoon. Water was pumped from the lagoon into the pond and allowed to flow back into the lagoon. The customer was not interested in denitrifcation, so the air was left on continuously. Samples were taken weekly to prove the nitrification efficacy of the technology and the information gathered was used to create the full scale design. The study resulted in a full scale installation.
