Abstract :
In a joint project the Universidade Federal de Uberl^andia and the German Aerospace Center are developing solar
water treatment technologies for industrial applications. Wastewater from chip-board production is difficult to detoxify
by standard processes. Different advanced oxidation processes using solar light were tested on this effluent. In opposition
to TiO2 treatment, the application of the photo-Fenton process using a compound parabolic collector (CPC) type
solar reactor shows excellent results, with a reduction in the COD higher than 70% with the application of about 800
kJm 2 of UVA radiation. HPLC analysis shows an efficient degradation of the organic matter present in the effluent
(formaldehyde, melamine, urea, wood extractives, lignin and urea/formaldehyde and melamine/formaldehyde resins
fragments) prior to their complete disappearance.
