Abstract

Bioremediation is the process using living organisms to clean up contaminated soil. The main advantage of bio remediation is that it allows soil to be treated without being excavated or transported. The rate at which microorganism degrade contaminants is influenced by specific contaminants and their concentration, oxygen supply, moisture, temperature, pH value, nutrients supply and bio augmentation. Treatability studies are conducted to determine the effectiveness of treatment process performance. In this project work, the work is carried out in three phases. In the first phase, the landfill sites in and around Chennai are visited to collect samples. The site characterization and soil analysis are done for five landfill sites. In the second phase, the soil samples collected are subjected to nutrient bio remediation. The effect of pH, temperature and biomass concentration is studied over a period of 30 days. The optimum condition for a good remediation of contaminated soil is achieved.
