A PROPOSAL FOR A FIELD-SCALE PILOT DEMONSTRATION UNIT FOR BIOREMEDIATION OF TNT CONTAMINATED SOIL

A reasonable field-scale operational scenario was developed as the hyp othetical TNT bioremediation unit. It is described in Appendix A and t ermed the Riffle-Pool Reactor, The two-stage system consists of TNT le ach-bed followed by a plant-pool bioreactor. Water is recirculated eit her continuously or intermittently over the riffle-bed TNT extractor a nd into the plant-pool reactor. A previously published manuscript enti tled ''Aquatic Plant Augmented TNT Degradation - Analysis of Reactor's Kinetics'' contains the kinetic parameter estimates needed to estimat e equipment design and operating parameters. This include the Monod ra te constant, dissolution constants and other kinetic parameters. This manuscript demonstrates how that basic information is incorporated int o the design of the pilot, field-scale demonstration unit.
