ABSTRACT:
A bioremediation system converts a waste stream, at least part of which is a fluid containing energetics, to carbon dioxide (CO2), water, and environmentally benign end products. It uses gas-enhanced sequencing-batch-reactors (SBRs), treating the waste stream in three SBRs seriatim. The first SBR uses a nitrogen purge, the second a hydrogen gas supplement, and the third an oxygen gas or forced air supplement. Each reactor may be supplemented with additives to optimize conditions such as pH, dissolved oxygen, and nutrient level. The system may be implemented under manual control, semi-automated, or fully automated, as needed. A waste stream of consideration is the pink water resultant from munitions fabrication and handling.
