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