Membrane Filtration Techniques - Part Ⅱ Scope for minimising effluent load

摘要

Membrane filtration technique is a practical and cost effective solution to the problems for handling textile wastewater pollution. In earlier article (Man-MadeTextiles in India, L(2), 58, 2007) it was illustrated that exhaust dye liquor of reactive dyes could be separated from unfixed dyes by membrane filtration technique at affordable cost. This would enable small process houses to survive and remain competitive. The main thrust area in this paper is the use of membrane filtration technology not only to purify incoming water, but also to recycle used water as many times as is practically feasible so that generation of effluent and treatment costs are reduced.
