Biological Treatment Plants for Textile Effluent
topic
Biological treatment of textile effluents uses activated sludge processes with extended aeration at sludge retention times of 15 to 30 days to achieve COD removal of 80 to 95 percent from biologically degradable dye auxiliaries, surfactants, and sizing agents, with membrane bioreactors combining biological treatment with ultrafiltration achieving effluent quality suitable for water reuse in dyeing operations at higher capital cost but lower effluent volume.
Role
Provides the primary COD and BOD removal from textile effluents through biological oxidation of biodegradable organic compounds, with biological treatment being the most cost-effective method for reducing the high organic loading from textile auxiliaries, surfactants, and hydrolysed sizing that represents the dominant pollution contribution of textile wet processing to receiving waters.
