Types Of Bioremediation

There are two main types of bioremediation

bullet

In-Situ Remediation

In-situ Bioremediation treats the contaminated soil or groundwater in the location in which it is found. In this technology oxygen and occasionally nutrients are pumped under pressure into the soil through wells.  The nutrients are spread on the surface to infiltrate into the contaminated area of material or the saturated zone.

bullet

Ex-Situ Remediation

Ex-situ Bioremediation requires pumping of the groundwater or excavation of contaminated soil prior to remediation treatments. Ex-situ Bioremediation can be further broken down into two main components or processes; Slurry-phase and solid-phase treatment.

bullet

Slurry-phase-    This treatment involves the initial combination of water with the contaminated soil and later degradation in a bioreactor.

bullet

Solid-phase-    This treatment achieves the similar goal of the former treatment yet, in this process, the contaminated soil is placed in a bed and nourished with nutrients, moisture and oxygen in hopes that decomposition will occur.
