About Indian Textile Industry Indian textile industry contribute to 4 % of GDP Indian textile industry contribute to 27 % of foreign exchange earning. Processing (Next Five Years) • Add. Proc. capacity built by 2017 -22 : 47 bill Mts. • Add. Capex (in 2017 -22) : € 6 Billlion. (Rs. 42000 Crs)
About Indian Textile Industry-Water • Approx. waste water volume of Indian textile industry = 3000 Million litre / Day. • Most centers are water scarce. • Water source of most center’s is ground water. • Waste water recycling is very low • Potential additional investment in water / waste water = Rs. 24000 crore (€ 3. 5 BILLION) • Potential Annual T. O in water / Waste water = Rs. 7000 crore (€ 1 BILLION) • Possible daily fresh water saving=2400 -2600 MLD
Challenges in Indian processing industry (In relation to water & wastewater) • Availability of water / High water consumption • Waste water treatment & Recycling • Discharge of treated effluent (Brine) • Disposal of solid waste generated during effluent treatment. • Compliance of environment laws and international protocols. • Inability to meet Pollution control norms & Zero Discharge. • Legal intervention of court. • Public Awareness

Eco Concept of Industry
Effluent Treatment /ZLD CETP (As per legal requirement) Recycling & ZLD Recycling (60 to 90 %) - Equalisation: Tertiary: Final cleaning collection tank for pre process for removal of mixing inorganic substances before - Primary : phisio chem recycle. treatment & Sludge -U F. -Ultra filtration for removal of setting - Secondary : Biological Treatment - Discharge : After Treatment effluent discharge to river micro particles -R. O. : With help Membranes removal of salt & other impurities from treated water. Reduce TDS -Other technologies ZLD (Options) - Solar Drying : Solar PONDS used for evaporate Treated effluent - Mechanical Drying : Evaporate Treated effluent with electro mech. eqip. Marine Outfall : Non useable Treated effluent discharge to Sea

Case study of Balotra- Cotton Textile Processing Centre (Local Locked Area) Rajasthan Balotra
Balotra, Rajasthan (Cotton Textile Processing Centre) Present Water Scenario • Balotra is a land locked area in Rajasthan Desert. • 350 Process houses, mainly small process house, engaged in cotton dyeing, Printing and processing they are spread in 5 areas. • Total water consumption is approx. : 50 -60 MLD • Water cost is ranging between : Rs. 35 to 70/ KL (€ 0. 50 to 1. 0) • Source of water is ground water. Cont….
Balotra, Rajasthan (Cotton Textile Processing Centre) Present Waste Water effluent Scenario • No discharge of treated effluent to river, restriction by Court. • No possibility of discharge into sea, as this is land locked area. So the left over has to be air dried / mechanically dried to evaporate water and salt has to be reused/ disposed. • This area has high temperature and strong sun throughout the year. This is low rainfall area. Good for solar evaporation.
