Advanced Oxidation Processes of Dyes in Bubble Column Reactor- A Solution to Degrade Textile Dyes in Effluent Stream

Conventional and traditional textile wastewater treatment processes is a challenge to environmental engineers and environmental scientists because of the restrictions on effluent quality by the environmental pollution authorities. Conventional degradation techniques have a disadvantage since 53% of 87 colours are identified as non-biodegradable. Besides dyes cannot be degraded by primary and secondary treatments. Primary treatment involves coagulation and flocculation while secondary treatment involves activated sludge process. Both of these treatments do not successfully degrade textile dyes. So the need for tertiary treatment process-advanced oxidation process such as ozonation. Bubble column reactor is an effective alternative to the environmental pollution problem. The present vision is to present effectively the importance of bubble column reactor and ozonation of dyes as the reaction medium in it.
