Surfactant enhanced bioremediation (SEB)
Surfactant Enhanced Bioremediation (SEB®) using Ivey-sol® involve the use of Ivey-sol formulations which are patented non-ionic surfactant mixtures used in the in-situ and ex-situ treatment of petroleum hydrocarbons, heavy metals, and more recently radioactive type contaminated waste. These surfactant formulations have the ability to enhance soil biodegradation. During In-situ and Ex-situ Bioremediation, the effectiveness of the bioremediation process is a function of balancing several physical ... |
