Zero Liquid Discharge (ZLD)
Concept: Recover and reuse 100% of water through integrated RO, evaporation, and crystallization.
System Components:
• High-recovery RO
• Mechanical / Multiple Effect Evaporator (MEE)
• Agitated Thin Film Dryer (ATFD) / Crystallizer
• Condensate polishing unit (CPU)
Output: Distillate (<50 ppm TDS) suitable for reuse; solid salts for disposal/recovery.
Benefits:
• Zero discharge to environment
• Water cost reduction by up to 70%
• Regulatory compliance for high-pollution industries
