BioSolve is used for both in-situ and ex-situ remediation projects. In-situ, BioSolve works to mobilize NAPL trapped in the soil and facilitate transmission through the aquifer for evacuation. Ex-situ, BioSolve can be used for soil and sand washing or for long-term bioremediation in a process known as “land farming.” In both cases, BioSolve mobilizes and solubilizes hydrocarbons, enabling extraction of up to 99% of the contaminant mass. Bioremediation of any residual contamination is also accelerated through enhanced bioavailability of hydrocarbons.
BioSolve works in three ways on soil remediation projects
BioSolve, a water-based, biodegradable surfactant formulation, functions in three ways to remediate contaminated soil:
Removing Non Aqueous Phase Liquid (NAPL) contamination trapped within subsurface formations is the core challenge in many remediation efforts. NAPLs have low solubility in water and therefore are not subject to efficient removal by many technologies. Injection of BioSolve solution into the vadose and/or smear zones can enhance remediation by:
Imagine a sandwich that is three feet thick. This meal is almost inedible because it is out of proportion with the size of the mouth. All one can do is nibble around the edges. In similar manner, trapped hydrocarbon masses are slow to biodegrade because their massive globular structure is out of proportion to the microscopic bacteria that naturally seek to ingest/process the oil.
How does BioSolve Work?
BioSolve microencapsulates the hydrocarbons (through the formation of micelles), resulting in a multiple order of magnitude decrease in droplet size and a corresponding increase in the surface area accessible to bacteria. This transformation makes the hydrocarbon readily digestible by the bacteria, thereby speeding up the natural biodegradation process.
