Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi or bacteria) to breakdown or degrade hazardous substances into less toxic or non-toxic substances. Several lakes have undergone bioremediation in recent years. Some myths have surfaced due to improper execution of the technology. The assumptions have been that mechanical aeration systems are critical to bioremediation, and that this is a slow process and is not appropriate in tropical conditions.
A study of the bioremediation projects over three different regions in the world i.e. Central Europe, Middle East and India shows that if executed properly then bioremediation would be a practical tool for Lake Management. It is very useful for controlling the water parameters and also various pathogenic microorganisms. Bioremediation can be swift and also implemented with little or no mechanical aeration systems. Bioremediation may not be applicable in each and every case. It requires highly specialized knowledge, and can be applied in most cases of lake remediation, including all kinds of weather conditions.
