Bioventing

Bioventing operating principles air injected at low rates can be extraction in some cases increase oxygen content oxygen limited conditions minimize mobilization of vapors enhance existing natural bioremediation may be able to use passive air injection may prevent intrusion of hydrocarbons vapors passive.

Bioventing. Source for information on bioventing. 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 is a process of stimulating the natural in situ biodegradation of contaminants in soil by providing air or oxygen to existing soil microorganisms. Bioventing uses low air flow rates to provide only enough oxygen to sustain microbial activity in the vadose zone.

Pada bioventing digunakan gerakan udara yang diinjeksi melalui tanah yang tidak jenuh atau tanpa. Definisi bioventing lainnya adalah proses penyuntikan dan ekstraksi udara menuju daerah vadose untuk menyediakn o 2 yang diperlukan untuk biodegredasi aerobik nugroho 2006. Bioventing cocok untuk kontaminan yang didegradasi melalui metabolisme aerobik dan memiliki tekanan uap kurang dari 1 atm. Bioventing the process for treating environmental contaminants in the soils located between the ground surface and the water table by inducing aerobic biodegradation.

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 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. Bioventing adalah penggunaan induksi gerakan udara melalui tanah tak jenuh dengan atau tanpa nutrient. 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.

In contrast to soil vapor vacuum extraction bioventing uses low air flow rates to provide only enough oxygen to sustain microbial activity. Bioventing dilakukan pada pengolahan kontaminan volatil yang sukar dibiodegradasi.
