... The first phase involves munitions processing The liquid hydrolysate containing TDG will be treated in and agent neutralization, which generates a secondary waste- the second phase of the process by using immobilized cell water stream, called hydrolysate, that requires subsequent bioreactors (ICBs) in the bio­treatment area (BTA)

The WRS tanks provide an equalof TDG and the planned design and operating procedures for ized feed to the evaporator system, where the water stream is pretreated to remove carbon dioxide through acidification 2 PCAPP, RCRA RD&D Stage III, Class 3, Permit Modification Request, and aeration before concentrating the brine stream through Revision 0, November 2006, Appendix D, Waste Analysis Plan, C-2a(3) water evaporation and distillation to recover water for (d)

... Once the ICBs are in a steady state, the 1:8 dilution of the agent hydrolysate and treatment goal of at least 95 percent destruction of TDG should maintain TDG concentrations well below toxic concentrations in the ICBs. Toxic inhibition may be a concern during start-up and off normal operation, especially if there is elevated loading of the TDG or periods with poor biodegradation of the TDG.
