Chementator: A faster way to decontaminate soil  

By Edited by Gerald Ondrey |

Liberty Engineering (Hamburg, N.Y.; www.libertypsa.com) has developed a bioremediation system that fully removes carcinogens from soil in 90 days. The process is based on microbial oxidation of organic compounds by petrophyllic pseudonomads in an oxygen-rich environment. The bacteria are specifically isolated for their affinity to metabolize heavy hydrocarbons, aromatic compounds and organic solvents. Bio-stimulation of the carcinogen killers is a key component of this new system, which is achieved by adding specific nutrients for the indigenous bacteria in an oxygen-rich environment, as well as bio-augmentation of bacteria selected for affinity to the specific contaminants. The contaminants are metabolized into biomass, water and carbon dioxide free of traces of hydrocarbons, toxins or pathogens. Since the utilization of aliphatic hydrocarbons by microorganisms is an aerobic process, organic material is processed up to 15 times faster than with the use of anaerobic digesters, says the firm. Liberty Engineering utilizes skid-mounted gas sparge equipment with microbes batch fed to a water tanker prior to distribution to the soil. The water tanker contains oxygenated feed water that has been dissolved at the required temperature for…
