Bioventing

Bioventing enhances the activity of indigenous bacteria and archaea and stimulates the natural in situ biodegradation of hydrocarbons by inducing air or oxygen flow into the unsaturated zone and if necessary.

Bioventing. Pada bioventing digunakan gerakan udara yang diinjeksi melalui tanah yang tidak jenuh atau tanpa. Bioventing the process for treating environmental contaminants in the soils located between the ground surface and the water table by inducing aerobic biodegradation. Bioventing cocok untuk kontaminan yang didegradasi melalui metabolisme aerobik dan memiliki tekanan uap kurang dari 1 atm. Bioventing adalah penggunaan induksi gerakan udara melalui tanah tak jenuh dengan atau tanpa nutrient.

Definisi bioventing lainnya adalah proses penyuntikan dan ekstraksi udara menuju daerah vadose untuk menyediakn o 2 yang diperlukan untuk biodegredasi aerobik nugroho 2006. Bioventing dilakukan pada pengolahan kontaminan volatil yang sukar dibiodegradasi. Bioventing is a process of stimulating the natural in situ biodegradation of contaminants in soil by providing air or oxygen to existing soil microorganisms. Air is introduced into the contaminated soils providing oxygen for native soil bacteria to use in the biodegradation of organic compounds.

Source for information on bioventing. Bioventing is an on site remediation technology that uses microorganisms to biodegrade organic constituents in the groundwater system. Bioventing uses low air flow rates to provide only enough oxygen to sustain microbial activity in the vadose zone. Figure 4 1 typical bioventing system bioventing is a promising new technology that stimulates the natural in situ biodegradation of any aerobically degradable compounds in soil by providing oxygen to existing soil microorganisms.

Passive bioventing in stratified soils and shallow groundwater conditions tds 2083 august 2000 describes the passive bioventing process where gases moving naturally in and out of the vadose zone provide enough oxygen for biodegradation rather than using a blower to inject or extract air. Bioventing enhances the activity of indigenous bacteria and simulates the natural in situ biodegradation of hydrocarbons in soil by inducing air or oxygen flow into the unsaturated zone and if necessary by adding.
