| Summary: | Water reuse and recycling, wastewater treatment, drinking water production
and environmental protection are the key challenges for the future of our
planet. Membrane separation technologies for the removal of all suspended
solids and a fraction of dissolved solids from wastewaters, are becoming more
and more promising. Also, these processes are playing a major role in
wastewater purification systems because of their high potential for recovery
of water from many industrial wastewaters. The aim of this work was to
evaluate the application of micro and ultrafiltration for distillery
wastewater purification in order to produce water suitable for reuse in the
bioethanol industry. The results of the analyses of the permeate obtained
after micro and ultrafiltration showed that the content of pollutants in
distillery wastewater was significantly reduced. The removal efficiency for
chemical oxygen demand, dry matter and total nitrogen was 90%, 99.2% and
99.9%, respectively. Suspended solids were completely removed from the
stillage. |
