Abstract

Expansion in technological advancements and urbanization, results in huge energy requirement at the same time requirement of alternate biological energy. A cost effective alternative energy production technique can be developed by using Thermal power-plant waste-water as a nutrient source and exhaust gas as an inorganic carbon source for micro-algae growth. The harmful effect of waste-water and exhaust gas of thermal power-plant is well known which can also diminished by coupling technology of remediation and bio-diesel production using micro-algae. Chlamydomonas oblonga has grown at indoor and outdoor conditions, which shows that in presence of 100% wastewater at outdoor conditions gives best result and provide specific growth rate of 0.188 d-1, hence this conditions were selected for large scale production of micro-algae. Total large scale culture was done with 60 liters of microalgae culture in glass bottles. Temperature was in the range of (20-36o C) with no aeration. Dry biomass produced is 1.087 g/l. Total dry biomass produced from 60 liter culture is 60.22 gms. Lipid content of C. oblonga grown in outdoor condition and wastewater is 29.72%. High growth rate was accomplished by Chlamydomonas oblonga in 100% waste-water and 7% carbon-dioxide from flue gas. Co-utilization of exhaust gases and waste-water can prompts to triple advantages, firstly energy production in terms of bio-diesel, secondly air pollution reduction through carbon dioxide sequestration and lastly water pollution reduction as well as waste utilization. As this technology is both environment friendly and economic viable, it can be applied for substantial scale production as integrated bio-diesel production plant combined with thermal power-plant.
