Abstract

Bubble column reactors are intensively used as multiphase flow reactors and reactors in chemical ,biochemical and petrochemical industries. Till recently its visionary potential is exploited in an effective and far-reaching manner in treating textile dye effluents, thus opening the window of innovation in the field of application of environmental engineering science. These reactors provide several advantages and benefits during operation and maintenance such as high heat and mass transfer rates, compactness and low operating and maintenance costs. Three phase bubble column column reactors are widely employed in reaction engineering,i.e. in the presence of catalysts and in the wide avenue of biochemical engineering. Textile waste effluents are one of the wastewaters that are difficult to degrade by primary and secondary treatment procedures and they contain recalcitrant compounds. So the need of a tool as a tertiary treatment process-ozone-oxidation or advanced oxidation process for treating textile dye effluents in a bubble column reactor. The aim of our study is to gain understanding and unravel the hidden secrets of the tool of bubble column reactor in degrading textile dye effluents. Fundamentals of the subject striving towards applied aspects of the ozone technology and its application are presented in this study with minute details.

In the second stage an attempt will be targeted to explore the kinetics of the ozone oxidation of dyes and the subsequent design of bubble column reactor. A particular pH and a particular redox potential will be found for a specific dye conversion of dye. A number of different types of dyes will be utilised-anthraquinone and azo dyes. It will open up a new area of environmental engineering science.

Application of nanotechnology in environmental engineering science is also a vision and mission of our study and research. Nanotechnology can be extensively used in developing safe drinking water for a growing population. The application of nanotechnology to the purification and treatment of water supplies to make them potable may potentially revolutionize water purification and treatment. Our future vision will lead towards this area of innovation.
