Performance assessment of activated carbon supported catalyst during catalytic wet oxidation of simulated pulping effluents generated from wood and bagasse based pulp and paper mills

Abstract

The present study reports the performance of catalytic wet oxidation (CWO) for the treatment of simulated pulping effluents (with chemical oxygen demand (COD) = 15 000 and 17 000 mg L−1) from large and small scale pulp and paper mills, respectively.

1. Noncatalytic and catalytic oxidation of organic pollutants in wastewater by air

“…This issue can be overcome by developing heterogeneous catalysts. Various solid catalysts for CWAO processes have been developed and are widely available, primarily based on either metal oxides , supported precious metals , or carbonaceous materials [12,[94][95][96][97][98][99][100][101][102][103][104][105][106][107][108][109][110]. They have been applied for the removal of organic pollutants, in particular phenols and substituted phenols, carboxylic acids, ammonia, dyes, and some N-containing compounds such as aniline and dyes, which have been comprehensively reviewed by Kim et al [111] and Stüber et al [112].…”
