Problems with textile processing wastewater treatment systems

• High volume of wastewater
• Scarce space available for in-plant treatment
• Complex nature of wastewater with dyes and auxiliaries
• Biological treatment unable to handle organic and hydraulic loads
• Larger treatment plant based on biological system are not viable – from engineering and economic point
• Manpower is not readily available to handle conventional plants

Xccelerated coagulation treatment of textile wastewater - Tomorrow’s technology today

Conventional process includes 4 to 5 treatment steps: Primary, Filtration, Secondary, Clarification, Tertiary. Generates sludge at multiple points and cannot be made automatic.

Electrochemical system for 100 KL/day textile house needs: 3 to 4 sq m of Area (excluding Filtration area), 8 to 10 HP of total power source. Treatment cost varies between 8 to 12 Rs./1000 liter. Capital cost in range of 10-12 Rs./Liter
