TETRA SAF is a simpler alternative to more complex treatments such as activated sludge and Biological Aerated Filters (BAF), which require more extensive operator input and process monitoring and control. The design encourages the growth of a robust biomass capable of consistently producing high quality effluents, even during large variations in hydraulic and biological loadings.
Ammonia and BOD can be removed in the same step or in separate reactors depending upon the wastewater treatment requirements. The biological reaction occurs in an aerobic environment. As the wastewater passes over the media, BOD and NH3-N are converted into biological solids. continuously released from the media bed. The solids are either removed via clarification or filtration depending upon system requirements.
