Each unit serves one of the three identical neutralization unit toxic cubicles. The Secondary Heat Transfer Fluid Circulation Module provides a boundary between toxic systems and the environment and prevents contamination of plant cooling water by toxic process fluids in the event of heat exchanger leaks.

C:onr] Them The vent streams from the HD reactors and the TCC Effluent Tank are combined, scrubbed with a sodium hydroxide scrubber, condensed and passed through dedicated carbon filters before entering the site cascade ventilation system.

The Biotreatment Module is designed to biologically degrade thiodiglycol and other compounds in the stripped hydrolysate using sequencing batch reactors (SBRs)

The Effluent Filtration Module removes most of the remaining suspended solids from the SBR supernatant in the Continuous Backwash Sand Filter. The filter effluent is stored in the Filtered Effluent Surge Tank for transfer to the Federally Owned Treatment Works.

In the feed preparation section, the air-stripped hydrolysate is biotreated so it can eventually be handled in the same federally owned treatment works (FOTW) that handles other wastes from Aberdeen Proving Ground.

Spent activated carbon from the various filters, estimated to be generated at a rate of 600 lbs/day, will be tested for 3X surety and sent to the same contractor that takes other carbon filter material from facilities at Aberdeen Proving Ground. Demilitarization protective ensembles, which are at the 3X level after normal decontamination procedures, will be placed in 55 gallon drums, stored in a solid waste storage area, and then shipped off site.
