Zero Liquid Discharge (ZLD)
Maximize recovery and minimize liquid discharge through advanced concentration.
What is this service?
Zero Liquid Discharge (ZLD) is a system designed to eliminate liquid waste by recovering and reusing all water, leaving behind only solid waste.
Typical process flow
- High-efficiency pretreatment
- RO / NF brine concentration
- MVR / ATFE evaporation
- Solids handling & salt recovery (as applicable)
- Energy and mass balance optimization
Benefits
- Regulatory alignment for sensitive locations
- Water recovery maximization
- Lifecycle cost modelling
- Pilot testing support before scale-up
Industries
Commonly applied in:
Textile
Pharma
Chemical
Tannery
Power
Case study snapshot
Developed a phased ZLD roadmap for a chemical park — combining tertiary treatment, RO reject management, and MVR with clear TDS / volume targets per expansion stage.
