Ozonation of Direct Red-23 dye in a fixed bed batch bubble column reactor

Abstract: This study reports the decolourization of direct Red-23 dye by ozonation in a fixed bed batch bubble column reactor. The conversion percentage for bubble column with media is reported high. This research enhances our concept that fixed bed batch bubble column reactor is effective in degradation of dyes. The large utilization of synthetic dyes is a matter of environmental concern since some of them are potentially toxic, mutagenic and carcinogenic
