TATA STEEL, Jamshedpur - Pilot Plant
Micro algae and sludge bacteria based Pilot plant to handle ammonia and Cyanide has been set up at TATA STEEL, Jamshedpur Plant by Phycospectrum.
Coke plant wastewater being rich in nitrogen and phosphorus sources can be easily employed for microalgal growth. In the process of growing microalgae in coke plant wastewater, the same is bioremediated and gets free from ammonia and cyanide upto considerable extent. The phenolic content is reduced as depicted by the colour change in the microalgae treated coke plant wastewater. There is 11.84% reduction in pH and 18.8% reduction in TDS as a result of microalgal treatment of coke plant wastewater within a span of three days. Furthermore, ammonia and cyanide content in case of microalgal treated coke plant wastewater is also reduced upto 90% and 80%, respectively. The amount of dissolved oxygen present in wastewater is also increased upto 30.60% after microalgal treatment. Thus, microalgae can be efficiently utilized for the removal of ammonia and cyanide content from the coke plant wastewater of steel and other industries. Moreover, microalgal treatment resulted in increasing the viability of activated sludge wherein the other operations of coke plant involving activated sludge organism proceeds efficiently.
