ABSTRACT:
A system for the treatment of nitrate-containing wastewater from home or commercial, not municipal, sources is described in which the wastewater is contacted underground by denitrifying bacteria introduced to the treatment zone periodically; the treatment zone being maintained at or above the temperature at which the bacteria are active on a year-round basis by the ground temperature.
