Abstract
A representative of Food processing waste water mixture of 8
pollutants (tannic acid, elagic acid, 2,4-dinitrophenol, gallic acid,
protecatechuic acid, vanillic acid, syringic acid and sinapic acid)
was treated by ozone and ozone combined with visible light. The
aim of these study is to determine the effect of operational
variables (pollutant concentration, O3 concentration and pH). For
this porpouse experimental design methodology based on
Doehlert matrixes has been used. Results show that Ozone is a
very effective treatment to degradate theese contaminants and the
combined use of O3 and UVA/VIS did not prove to be
advantageous, except for case with worst operational conditions.
