Bioventing, Technology that Clean Environment
In general, bioremediation is the process of cleaning contaminated soil, water, and other pollutants in our environment by using the microorganisms. Bioremediation was invented by George M. Robinson in the 1960s . There are many ways of bioremediation, one of which is bioventing. Bioventing is an in situ technology that stimulates microorganisms using addition of gas to degrade contaminants in the soil like petrochemical compounds including gasoline, fuel oil and asphalt . Bioventing involves gas into the unsaturated (chemical science) zone to increase the biodegradation of contaminants by microorganisms. The most common application of bioventing is to introduce air to increase the oxygen to stimulate biodegradation of petroleum hydrocarbon contamination. Other less common applications like anaerobic bioventing that to treat chlorinated ethenes have been repo...
