Sustainable Development of the Textile Industry in Tirupur with ZLD
Textile exports quota curbs were lifted in 2005, subjecting the Tirupur export industry to the growth path. By the mid of 2007, the exports from Tirupur grew to Rs.110 billion. The industry earnings quickly started hitting a low by 2008-09 and one of the major factors were the environmental issue. In 2011, the Madras high court had ordered the closure of all the wet processing units in Tirupur and ruled that the industries couldn’t operate until zero liquid discharge was attained. This led to the revolution in Tirupur, whereby, all the industries, commissioned the tertiary treatments of wastewater using membrane filtration technology and evaporators.
The scope of this paper is to explore the sustainable measures taken in the textile industry in Tirupur and the efficient functioning of the zero liquid discharge mandate that has placed Tirupur on the path of sustainable development. For this study, 2 individual effluent treatment plants (IEPT) and 4 common effluent treatment plants (CETP) were studied. The treated water characteristics were confirming to the standards. The conclusion from the study of the water characteristics analysis is that the CETPs and the IETPs are confirming to the zero liquid discharge regulations norms.
