Abstract
The colour manufacturing industry represents a relatively small part of the overall chemical industry. Dyes and pigments are highly visible material. A major source of release of colour into the environment is associated with the incomplete exhaustion of dyes onto textile fibre from an aqueous dyeing process and the need to reduce the amount of residual dye in textile effluent has thus become a major concern in recent years. The purpose of this study is to evaluate the efficiency of ozone and UV on the removal of 5 different dyes from fresh and sea water and the effect of these final compounds on some marine organisms . the obtained results for the five studied dyes can be summarized as the following :-
This study investigated the feasibility of applying ozone (O3) and O3 combined with ultraviolet (UV) to decolorize and detoxify the content of synthetic wastewater containing dye. Epermintal parameters including pH, initial dye concentration and reaction time were evaluated in a batch reactor to obtain the optimal operation conditions. Decolorization of the aqueous dye solutions, disappearance of the parent compound and measurement of chemical oxygen demand (COD) WERE THE MAIN PARAMETERS MONITORED IN THIS STUDY. THE result of the study showed that initial dye concentration and ph dominated the effectiveness of the decolorization process.
