Techno-Economic Assessment of Physio-Chemical and Anaerobic Treatment of Textile Wastewater from the Textile Industrial Clusters in Tiruppur.

Abstract

The HUASB reactor was started successfully using real textile effluent. The treatability study carried out for the textile effluent using the reactor revealed that such low strength textile wastewater could be treated by the system efficiently. The HUASB attained steady state condition on 135'th day at an OLR of 0.60 kg COD/m³ /day. The normal operation of the HUASB reactor lasted from OLR of 0.60 to 0.81 kg COD/m³ /day. The VFA content varied from 90 to 111 mg/L during the stable operation period. The maximum VSS and TSS removal was 64.5 and 73% respectively. Biogas generation was maximum (566.7 mL/day) at 0.81 kg COD/ml/day OLR. The HUASB system was more effective in organics removal than physio-chemical treatment in operation in the CETPs in Tiruppur.
