Abstract
Coal gasification plant is having the process of producing syngas, a mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and water vapor (H2O) from coal and water, air, and/or oxygen (Jindal Steel & Power, Coal gasification process and information on the JSPL Angul plant. https://www.jindalsteelpower.com/odisha.html. Accessed 17 Dec 2021, 2020).

During a coal gasification process, high volumes of used waters containing organic and/or inorganic compounds are generated. The specific characteristics of waste water from coal gasification plant water are directly related to the operation of gasification plant.
In Angul, waste water from coal gasification plant after treating in BIO-ETP (by others) and from cooling tower blowdown is being recycled for cooling tower makeup after treating in tertiary effluent treatment plant which is designed and constructed by Wabag.
