A Comparative Study on the Application of Algae for Bioremediation of Cooum Water

Biological treatment is an important and integral part of any waste water treatment plant that treats waste water from either municipality or industry having soluble organic impurities or mix of the two types of waste water sources. The advantage of mass cultured microalgae has advantage over conventional aerobic wastewater treatment systems as it reduces the cost due to the decrease in energy input. Aerobic wastewater treatment system is the need to supply oxygen in adequate concentration to the various microbes that will decompose the pollutants in the wastewater. Conversely, in a microalgae wastewater treatment system, oxygen is supplied as a direct product of the photosynthesis process. The micro algae can grow well at a very fast rate than land plants and they have the ability to double their biomass within a day. The micro algae are cosmopolitan found in different ecosystems even in extreme conditions. The micro algae fixes atmospheric CO2, at the same time it can also utilize flue gas rich in CO2 and CO3 even with sulfur and heavy metal content. The removal of nitrogen, phosphorous and toxic metals from domestic waste water by micro algae and their effective role in the processing of domestic waste water have been studied well. Thus treatment of domestic waste water using micro algae is an environmental friendly, no pollution treatment method where the biomass can be reused and recycled. Industrial waste water can also be treated with the micro algae before being dumped in to the natural fresh water resources. The present study is aimed at using Algae for the Bioremediation of Cooum Water
