Abstract
The textile industry is characterized by huge water consumption and produced wastewater. The end-of-pipe treatment
technology moves an undesirable waste material from one medium to another, thus tending to create chains of waste
products.
The alternative solution of water pollution control at the source significantly reduces the pollution load. In the present
study, the cleaner production (CP) opportunities for a cluster of five textile factories versus end-of-pipe treatment have
been investigated. The CP opportunities proposed are the following: replacement of acetic acid by formic acid,
elimination of the bisulfite treatment step after full bleaching of cones or fabric, replacing chemical scouring by bioscouring, avoiding the use of carrier in polyester dyeing and replacing mono-functional reactive dyes by bi-functional dyestuffs. The use of Upflow Anaerobic Sludge Blanket (UASB) reactor, followed by either activated sludge treatment
or chemical coagulation treatment, can produce treated effluent satisfying the Egyptian standards regulating wastewater
discharge into receiving water bodies.
