Water Bio Remidiation
The implementation of various developmental projects and rapid industrialization globally led to the generation of waste material consisting of organic, inorganic, heavy metals etc., majority of which, are hazardous and have a serious influence in environmental degradation.
As the above waste material finds its way into the water bodies, the negative influence on the environment is reflected in affecting Health of people, Aquatic life and reduced agricultural yields. It has become a gigantic task of treatment and management.
Various technologies developed to resolve the above issues for the treatment and management of these wastes included physical, chemical, and biological methods either individually or in combination. The most easy and economical method found suitable and eco-friendly is bioremediation processes.
Bioremediation processes
• Use Natural microorganisms to breakdown toxic, hazardous substances by aerobic and
anaerobic means.
• Can be applied at site or off site in treatment plants

The main types of Bioremediation comprise of
- Bio-stimulation: Nutrients and oxygen are added to the contaminated water leading to the growth and activity of bacteria. This results in the reduction of the pollutants. The progress of the remediation process is evaluated by checking the contaminant levels.
- Bio-augmentation: Microorganisms known to treat a particular contaminant are added to the polluted water in treatment of pond or tank. This method is suitable for off site treatment of the contaminants as the desired conditions for microorganisms growth cannot be made available at site. In this case, the reaction time can be controlled.
- Intrinsic Bioremediation: This remediation process is taking place naturally in polluted medium. This process is due to the activity of microorganisms and is observed in areas affected by petroleum contamination.
The above methods are either used individually or in combination. For solid waste, soil or sludge the nutrients and oxygen is made available by the use of suitable mixing techniques.
