Accelerating bioremediation using a particular surfactant

摘要

Soil can have non-aqueous phase liquid (NAPL) contaminate/s spilled onto or into it. When this happens the NAPL's tend to migrate down as a separate liquid phase and disperse into the soil matrix until they become trapped in the soil as immobile droplets or ganglia. NAPL's tend to follow high permeability path ways and spread along low permeability layers. The disposition of NAPL's in the soil matrix can be in one or all of the following forms: · evaporate and stay in the vapor phase, · adsorb onto solid surfaces · dissolved into the soil moisture.
