BIO NATIONAL CORPORA'T'ION <br /> 6 OPERATIONAL PROCEDURES <br /> 6.1 INSTALLATION OF THE SYSTEM <br /> 61.1 Installation of a 10-20 mil plastic, membrane on the surface, and <br /> over a barrier berm of 36" height, thin, preventing into usion of <br /> contaminants back into the underlying soil, and allowing collection of <br /> excess fluids in system for return to the bioreactor. <br /> The berm is constructed of clean soil to insure containment of all <br /> materials. Since the system is merely "wetted" with a limited supply of <br /> watery inoculum, and not saturated, there is no chance of excess fluids <br /> overflowing the berm. <br /> 6 1.2 Place pexfozated PVC vent lines on linea as directed, and cover to <br /> three to four feet depth with contaminated soil, being careful to have <br /> enough overburden to support the earth moving equipment. <br /> 6.1.3 Place inoculum delivery system on tarp of contaminated soil. � <br /> 6.1.4 Connect water--based inoculum supply and controls to delivery <br /> systems. <br /> 6 1.5 Connect rent lines to bioreactor aeration eductor. <br /> 6.2 ACTIVATION OF THE SYSTEM <br /> 6.2.1 Activate system as directed, adjusting inoculum delivery for <br /> gradual wetting of contaminated material. <br /> 6.2.2 Monitor for maximum biological activity and adjust nutrient and <br /> microbe insertion as required. <br /> 6 2.3 Monitor bioreactor system exhaust for presence of volatilets Adjust <br /> eductor flow and/or collect in either a carbon canister or oxidlzr- in an <br /> ozone generator package, as required. <br /> 6.2.4 Determine from early operations the trrrze cycle of "on--off", "sola <br /> inoculation" and "aeration only", as required <br /> s <br /> g T11OR901 <br />
