ABSTRACT:
A method and system for carrying out the bio-degradation of perchlorates, nitrates, hydrolysates and other energetic materials from wastewater, including process groundwater, ion exchange effluent brines, hydrolyzed energetics, drinking water and soil wash waters, which utilizes at least one microaerobic reactor having a controlled microaerobic environment and containing a mixed bacterial culture. By the method of the present invention, perchlorates, nitrates, hydrolysates and other energetics can be reduced to non-detectable concentrations, in a safe and cost effective manner, using readily available non-toxic low cost nutrients. The treatment of significantly higher concentrations of perchlorate, nitrate, etc. (<1.5 wt %) than was previously contemplated is made possible.
