Comparative performance of an UASB and a biofilm reactor with Opuntia imbricata as a support in the treatment of textile industry wastewater


Search for new strategies to increase the efficiency and economy of the treatment process has lead to the introduction of new materials. Department of Biotechnology of Autonomous University of Coahuila, Saltillo has been working with Opuntia imbricata as a natural support for t-he development of aerobic and anaerobic biofilm reactors to be used in the treatment of various kinds of wastewater for the last four years. The objective of the present study was to evaluate and to compare the kinetics and removal efficiency (RE) of an UASB reactor with a biofilm column reactor packed with natural support, O. imbricata (NS). The performance of both reactors was evaluated at different HRT and it was observed that a HRT of 30 h recorded maximum treatment efficiency. At this HRT, COD removal in the UASB reactor was 73%, where as it was 90% in biofilm reactor. Our results demonstrated that anaerobic biofilm reactors packed with Opuntia imbricata improved the efficiency of treatment and can be a better alternative to traditional reactors in the treatment of textile industry wastewater.
