Membrane Separation Processes and Advanced Oxidation Processes of Dyes in Bubble Column Reactor-A Keen and Far Reaching Overview

The vision of environmental engineering is wide, varied and unparalled. The changing world has prompted scientists to target towards green chemistry and green engineering. Green engineering encompasses environmental engineering. The path of success is visionary. Environmental engineering along with dye degradation techniques is ushering in a new era and new vision environmental pollution control. Conventional and traditional textile wastewater and effluent treatment procedures are a challenge to environmental engineers and environmental scientists because of the restrictions on effluent quality by the environmental pollution control authorities. Dyes cannot be destroyed by primary and secondary treatments. Primary treatment encompasses coagulation and flocculation while secondary treatment involves activated sludge process. Both of these treatments do not successfully degrade textile dyes and the dyes are recalcitrant to these treatments. So the need for tertiary treatment process-advanced oxidation process such as ozonation. Bubble column reactor is an efficient and visionary alternative to the environmental pollution problem. The present aim and objective is to present and project effectively the importance of bubble column reactor and ozonation of dyes as the reaction medium in it. The vision of advanced oxidation process will move towards a newer direction if science and technology surges in this new visionary area.
