THE CHALLENGE
Close the loop on high-strength industrial effluent
The plant needed to maximise water recovery, achieve ZLD and reduce freshwater dependency through a sustainable closed-loop water-management system.
ENGINEERING APPROACH
Engineering approach
Clarification, filtration, membrane systems and evaporation enable high water recovery, process reuse and efficient reject management.

PROJECT OUTCOMES
Treatment, recycling and reuse
- 01
ZLD compliance
Achieved zero liquid discharge in compliance with GPCB norms.
- 02
Process reuse
Recovered treated water is utilised within the plant, reducing freshwater consumption.
- 03
Water recovery
Achieved 90–95% water recovery through membrane and evaporation technologies.
- 04
Reject management
RO reject is effectively managed through MEE.
- 05
Sustainability
Strengthens water security while supporting sustainability and ESG commitments.
