Removal of Chemical Oxygen Demand from Textile Industrial Wastewater by Anaerobic Digestion

This work focuses on monitoring the COD removal by anaerobic digestion of liquid textile wastewater under controlled conditions. A laboratory scale models of anaerobic digester of 8L capacity, with gas collecting bottles were setup to treat textile industry wastewater. The performance of the reactor in removing COD, Total Solids and Alkalinity were studied, with reference to different organic loading rates of 0.01, 0.02, 0.03 kg COD/m3.d. The highest yield of alkalinity, percentage COD removal and total solid is 1123.28mg/L, 62.49% and 89.28% respectively.
