Abstract
Introduction. Solar decontamination of waste waters
with dye used in textile industries, by the use of photosensibilators,
will avoid the arrival of organic compounds
to hydric resources, as it happens with some
dyes. This will also allows that potabilization plants
are able to capture waters that are easier to treat, and
to lower the extinction risk for aquatic plants and animals.
This treatment is a clean technology because
it uses solar energy, which does not contaminate,
uses not polluting photosensibilators and does not
generate toxic sub products or mud because organic
compounds have a mineralization process. Besides,
photosensibilators can be recovered and reused.
Objective. To treat waste water from textile industries.
Material and methods. A cylindrical parabolic
composed solar collector was used. Based on the
results obtained in the research of degradation of
reactive orange 84 dye, the best conditions were chosen
for degradation and mineralization from that research
in order to apply them to a waste water from a
tricots dyeing industry containing that colorant. Results.
The best conditions were those obtained with
the AM3 ( 77,77%) rehearsals, were we used 80 mg/
L of TiO2, 3 mL H2O2/L and air. The mineralization
percentage was 66, 29%, and this was the maximum
obtained in the rehearsals with waste water and it was under these same conditions. Conclusion.
Six experiments were made with three replicas
for each one. We worked with three waste water lots,
containing different colorants, though there were reactive
orange 84 in all of them. We got good percentages
of color decrease at 604 nm.
