BioMicrobics - Anoxic BioFilter Clarifiers (ABC)
ABC (Anoxic BioFilter Clarifiers) is a family of specialty clarifiers. Each of these devices are designed for use as a secondary clarification device after FAST.
What is ABC®?
- ABC®-N: Used when very low total nitrogen numbers are required for the effluent.
- ABC®-C: Used to settle out additional TSS in secondary effluent.
- ABC®-P: Used when very low phosphate numbers are required for the effluent.
ABC®-N: A chemical feed pump supplies a carbon source to the waste stream exiting the FAST treatment tank; the ABC-N promotes the growth of bacteria that will denitrify the wastewater before discharge into the receiving environment. The ABC-N acts as a post-anoxic denitrification process.
ABC®-C: Secondary effluent flows up through ABC-C media, reducing the velocity of suspended solids and promoting settling. Clarified effluent leaves the ABC-C through a built-in baffle connecting to the outlet of the tank.
ABC®-P: A chemical feed pump adds a phosphorous-precipitating chemical into the waste stream exiting the FAST treatment tank; the ABC-P promote the flocculation and coagulation of the phosphorous, which then settles out of the wastewater.
