The results showed that color of all fours reactive dyes were eliminated. The Jar-test compared experiment was also tested with low removal capacity. Once again, the results indicate a strong capacity of microwave technology on colors removal. | At the first step, the appropriate condition for the absolute elimination reaction of dyes and a part of organic substances of the active dyes by microwave radiation process was found. The Jar-test showed that dyes containing the reactive blue 21 solution (ptalocianin group) may be discolored quite well with coagulation and flocculation process (52%). But the dyes of other groups (azobenzen and antraquinon) showed the very poor results. It affirms the dominance of microwave-based dye treatment in comparison with flocculation method. Although, this subject investigated so thoroughly some of factors which influence on the microwave-based discoloration process, the reactive kinetics still has not been studied sufficiently yet. The next studies should clarify some matters such as: Determining in-process products of the dye decomposition process via the indicators: IC, LC/MS, etc. and opening the study for the other difficultly treated subjects of sewage water such waste leaking water, pesticides, surface-active agents and so on.
