Decontamination of Wastewater
Containing Explosive and Organic Wastes

Nitroglycerin mitigation at Naval Surface Warfare Center
Indian Head, Maryland

  • Designed, fabricated and operated a microbial treatment system for treating wastewater containing nitroglycerin (NG) and acetone.
  • Used Tetrahedron's own microbes (Tetrabac) and nutrients (Tetranute-1) to accomplish the task.
  • The waste was generated by a Naval Production Facility in Maryland.  Reduced concentration of NG down from 255 ppm to non-detect (<0.2 ppm).
    Reduced concentration of acetone to non-detect levels.
  • Ensured safety by selecting material of construction and developed operating procedures for the treatment system that passed the strict hazard evaluation criteria set by the U.S. Navy.


Schematic of the water treatment unit designed and built by Tetrahedron, Inc. for NSWC.  The unit is capable of remediating wastewater containing NG at concentrations of up to 255 ppm.
