Bioremediation is a classical method for the reduction of TPH levels is soil. It is the process of using organisms to convert hazardous pollutants into less toxic compounds and involves the manipulation of the process of molecular degradation of compounds through biological Activity.
NCC has been using UTILECO (SPAIN) technology for bioremediation project. The nutrients supplied by UTILECO are all made out of natural materials.
Advantages:
• Can be highly specific
• Less expensive than excavation or incineration processes
• If mineralization occurs get complete degradation and clean up
• Does not transfer contaminants from one environment to another
• Uses a natural process
• Good public acceptance
• Process is simple
