In a typical soil remediation site, the level of contaminants can decrease without any treatment in the early stages after a spill. This is due to both evaporation and the action of resident bacteria populations. The contaminants that show this "natural" decrease are typically the volatile and easy to digest, low molecular weight, organic contaminants. Adding a bacterial inoculant, BIN, which is a conventional remediation approach, might accelerate the biodegradation rate, but results showed only a nominal reduction in the current test, from 15% to 18%.ACCELL® ADVANTAGE: Accell® SBR
, with no inoculant added, and that relied on resident bacteria populations, reduced the Total Petroleum Hydrocarbons by 24%. This equates to an increased rate of biodegradation of 200% (3 times) compared to bacteria alone, using water control as a basis.
In some instances, resident bacteria populations may be too low to provide adequate bioremediation. Accell® SBR
can boost the performance of such inoculants and enhance remediation effectiveness, in applications where engineered bacteria are added in order to enhance bioremediation.
The accelerated biodegradation rates when using Accell® SBR
opens up possibilities for on-site bioremediation to reduce costs by simplifying the process and reducing the time it takes to bring a site into compliance with regulatory requirements.
