ABC - Nitrogen

In certain site conditions, such as the drain field being too close to a lake, river or stream, the Total Nitrogen entering the waterway from the septic system may have a negative environmental impact. Unconfined aquifers may also be harmed by the entrance of Total Nitrogen into the sub-surface water.


Local regulations may require that additional measures be taken to reduce the Total Nitrogen to specific levels to eliminate or reduce the accumulative effect of the Total Nitrogen. In these situations, The ABC-N can be added after the MicroFAST® unit to further reduce the Total Nitrogen.


The introduction of a carbon source by a metering pump and the ABC-N is used in these situations. The selection of the ABC-N is based on the daily sewage flow from a residence. Facilities that have a higher concentration of ammonia-nitrogen (such as a school or church) will require a site specific design and equipment selection.
