Introduction:Effluents contains dyes Because of the adverse health effects of Environmental and dangerous for public health. The aim of this study was to the use of a combination coagulation and flocculation process Coupled with photocatalytic degradation in dye 2- (methoxy carbonyl amino methyl) - acrylic acid methyl ester from Synthetic wastewater.
Methods: In this study, the color removal with the help of coagulants and photocatalytic process was carried out in batch reactors. Parameters of the color concentrations, titanium oxide nanoparticles concentrations, beam intensity, contact time, pH and COD were investigated. The remaining dye concentration was determined by using a spectrophotometer.
Results: the results of this study showed that the color and COD removal by coagulation and flocculation process in optimum conditions, 72 and 58/5 percent obtained respectively. And subsequently by using photocatalytic process (TiO2/UV-A) highest percentage removal color and COD in concentration of 150 mg /L of nanoparticles and light intensity of 480 µw/cm2, 98 and 90.8 percent respectively, in contact time of 75 minutes and Equal pH of 6 was reported.
Conclusions: According to results, the application of integrated process coagulation and flocculation Coupled with photocatalytic degradation (TiO2/UV- A) in dye 2- (methoxy carbonyl amino methyl) - acrylic acid methyl ester and COD Under optimal conditions Obtained is very impressive and can be used in wastewater treatment automotive industry.
