BIOREMEDIATION WITH FYREZYME A FIELD-ORIENTED_ APPROACH ENHANCED BIOREMEDIATION: The FyreZyme Advantage FyreZyme is a multifaceted bioremediation enhancing agent crhith is k highly effective, thorough, simple to use; cost-effective and non- r-oxic . Laboratory bench tests have. been confirmed in a field demonstration, conducted and :,monitored by Mobil Oil ' s independent contracting agency. . Such "surface". bioremediation, proceeding to non-detect levels in only 14 days, is now being followed by in-situ utilization' or Fy_eZT.ne technology. The FyreZyme technology, whilA elegantly Y s; m- le is .scientifically sound and is easily applied for the cleanup c,r contaminated surface and subsurface - soil as well as- ground-water . k FYREZYME FIELD USE: FyreZynie is diluted with water for spray or injection application to contaminated soil, water, or aquifer. The F FyreZyme concentration is recommended to be 4% for TPH under 1,000, 5% for TPH of 1000-5000, and 6% E if beyond. Thirty gallons of such a 4,5, or 6% dilution treats 8 cubic yards of contaminated soil. The application is done by dividing the solution into 5 equal amounts and applying 115 of the total amount at weekly intervals. Field moisture is maintained at 80% of capacity between applications. Should petroleum C contaminate a body of "reachable" water, FyreZyme is used of a ratio of one gallon of FyreZyme per 100 gallons of contaminant present in the water. i The most rapid and cost-efficient method of treatment is to spread the contaminated soil on the surface in 12- inch lifts and treat under optimum aerobic conditions. However, by combining FyreZyme with other technologies, one can move a "front" of FyreZyme-laden water and/or air through the soil horizontally, vertically, or tangentially through venting/injection wells, infiltration galleries, elutriate recycling, air injection, etc. i FYREZYME IN-SITU; VADOSE AND GROUND WATER By utilizing a combination of injection and extraction; wells, or strategically placed infiltration galleries and by recirculating ground water, itis possible to move a front of FyreZyme through the soil. At the same time, aerated water and/or atmospheric air is moved with the front, creating a zone of oxygenation of the subsurface. This leads to formation of Lin aerobic zone in which conditions are made optimum for rapid, thorough aerobic bioremediation. With the movement of FyreZyme, water, and air through the contaminated soil, petroleum hydrocarbon contaminants are rapidly eliminated through bacterial action, enhanced by the multifaceted ingredients of FyreZyme. B ke'eping the soil at no more than 80% of field holding capacity, there little concern for unwanted effect on the ground water. Should the ground water already by contaminated, recirculating it through the aerobic zone undergoing enhanced bioremediation will cleanse it well, once it has been aerated in the transit between the extraction and injection wells. By maintaining this circuit as a closed- loop, no VOC release should occur. -
