ABSTRACT
Wastewater treatment is a crucial issue in the textile industry, which
generates plenty of polluting effluents containing significant residual
dyes and dyeing auxiliaries. The most frequently adopted biological
treatment may be ineffective in degrading dyes satisfactorily and is
extremely time consuming. Therefore, some other approaches, which
employ chemical oxidation to remove contaminants, have been
developed. Among them, ozonation technology has been thought
to be a promising approach due to merits of ozone. This chapter
concentrates on the application of catalytic ozonation promoted
by carbon aerogel (CA) materials for wastewater treatment and
reuse. The catalytic performance of the catalysts in the degradation
of the typical anthraquinone dye, C.I. reactive blue 19 (RB19), in
simulated dyeing wastewater is discussed in detail in this chapter.
