(532u) Textile Wastewater Treatment Using Coiled Flow Inverter (CFI) As a Photo-Reactor

The current research focuses on the photo-degradation of textile industry wastewater utilizing a coiled flow inverter (CFI) reactor. The textile industry is one of the oldest and most complex, and cleaning wastewater discharged from textile mills is still a challenge. The demand for textile materials and synthetic fibers increased proportionally with the expansion and development of these things, resulting in the creation of massive amounts of wastewater. Chemicals released into the environment as wastewater not only damage the ecology and aquatic life, but also have an impact on the health of humans living nearby.

CFI is static mixers that can provide higher mass transfer rates and therefore lead to higher degradation efficiency when compared to a straight-tubular reactor. Photochemical based degradation systems for waste water treatment are still in the early stages of development. And batch photo-reactors require large durations. We have synthesized copper-nickel hybrid nanoparticles from the extract of Moringa oleifera leaves using sunlight as the energy source. The nanoparticles were analyzed using FTIR, DRS, and XRD techniques. The same nanoparticles were utilized in a continuous flow system to degrade real textile effluent containing orange dye obtained from a textile mill. The photochemical degradation test were carried out using a CFI made of borosilicate glass, with a hold-up volume of 50 mL. CFI consisted of several coiled-loop sections, with each section bent at 90º to the previous one. There were a total number of four such sections arranged in square configuration. The photo irradiance was provided by visible light source, sunlight and ultra-violent lamps.The wastewater flow was induced using a peristaltic pump fitted with silicon tubing. The present study addresses and discusses the influence of process variables such as effluent flow-rate, catalyst loading, and light source on photo-degradation of effluent containing orange dye.
