ZLDX™ – WHERE INNOVATION MEETS COMPLIANCE – FROM CONCEPT TO COMMISSIONING

ZLDX™ is InfraCorp’s flagship integrated Zero Liquid Discharge (ZLD) platform, engineered to eliminate industrial wastewater while maximizing resource recovery. By seamlessly combining InfraCorp’s next-generation membrane systems—such as CloseRO™, HCRO™, HyO-RO™, and Therma-RO™—with advanced evaporation and crystallization technologies, ZLDX™ delivers a complete, high-performance pathway from wastewater to reusable water and solid recovery.

With ZLDX™, InfraCorp enables industries to transform wastewater liabilities into strategic assets, achieving regulatory compliance, cost efficiency, and sustainability leadership—all in one unified platform.

TECHNOLOGY INTEGRATION

ZLDX™ integrates:

  • Pre-Concentration via InfraCorp Advanced RO technology
    • CloseRO™, HyO-RO™, and HCRO™ optimize water recovery while reducing brine volume and energy usage.
  • Thermal Concentration via Evaporators
  • MVR™ handle scaling, high-TDS, and viscous brines with energy-efficient performance.
  • Achieve near-zero or zero liquid discharge
  • Concentrate brines for final crystallization
  • Recover reusable water and reduce waste volume
  • Ensure environmental compliance for industrial discharge
  • Final Solids Recovery viaCrystallizer produce high-purity solids for disposal, reuse, or value extraction.

ZLDX™ – VALUE PROPOSITION

ZLDx™ is InfraCorp’s cutting-edge Zero Liquid Discharge solution engineered for industries with high regulatory, environmental, and sustainability requirements. Utilizing an integrated Falling Film Evaporator (FFE) and Crystallizer process, ZLDx™ ensures complete wastewater elimination, high water recovery, and minimal environmental footprint.

PERFORMANCE HIGHLIGHTS

  • >98% Water Recovery, reducing freshwater demand
  • Zero Liquid Discharge compliance for even the toughest effluents
  • Energy Optimization through MVR, FO-RO hybridization, and multi-effect systems
  • Material Recovery including salts, metals, and valuable byproducts
  • Automated Control & Monitoring with full system integration

KEY VALUE DRIVERS

  • High Efficiency & Energy Optimization
    The Falling Film Evaporator enables rapid heat transfer with minimal energy use, significantly reducing operational costs compared to traditional forced circulation systems.
  • Maximum Water Recovery
    ZLDx™ achieves up to 95–98% water recovery, transforming waste into reusable clean water, supporting closed-loop recycling, and reducing freshwater dependency.
  • Solid Waste Minimization
    The integrated Crystallizer produces dry solids or salt crystals from the brine stream, minimizing landfill disposal volume and potentially creating marketable byproducts (e.g., NaCl, CaSO₄).
  • Scalable & Modular Design
    ZLDx™ systems are modular and adaptable for varying capacities (from pilot to full industrial scale), making them ideal for sectors like textiles, pharmaceuticals, chemicals, power, and petrochemicals.
  • Compliance & ESG Leadership
    Enables full compliance with stringent discharge regulations and supports environmental, social, and governance (ESG) goals by achieving zero liquid discharge and reducing ecological impact.
  • Smart Automation & Remote Monitoring
    Integrated controls and real-time performance monitoring allow seamless operation, proactive maintenance, and reduced manpower.

Differentiators

  • Proprietary ZLDx™ process design for enhanced brine concentration and crystallization.
  • Optimized heat recovery loops to reduce steam demand.
  • Compact footprint with high uptime and low maintenance costs.
  • Integration-ready with upstream MBBR, RO, or nanofiltration units (e.g., BioSep™, Min™ZLD).
