Optima Water Solutions is a ZLD Plant Supplier in Delhi NCR. We design and install Zero Liquid Discharge (ZLD) Plants that eliminate liquid effluent discharge completely. ZLD is mandatory for textile, distillery, sugar, tannery, and other industries under CPCB norms. Our ISO 9001:2015 certified systems combine membrane technology with thermal evaporation to recover maximum water and produce only dry solid waste.
What is a Zero Liquid Discharge Plant?
Zero Liquid Discharge (ZLD) is a water treatment process in which all wastewater is treated and recycled — no liquid effluent is discharged to the environment. The process concentrates all dissolved salts and contaminants into a dry solid (cake) that can be safely disposed of or further processed.
A complete ZLD system typically combines: Effluent Treatment Plant (ETP) → Reverse Osmosis (RO) → Multiple Effect Evaporation (MEE) or Mechanical Vapour Recompression (MVR) → Agitated Thin Film Dryer (ATFD) or Spray Dryer.
The CPCB and State PCBs have mandated ZLD for highly polluting industries including textile dyeing, distilleries, sugar mills, tanneries, and pharmaceutical bulk drug manufacturing units across India.
Zero Liquid Discharge Plant in Delhi NCR — Why It Matters
ZLD demand in NCR is limited compared to Gujarat's textile belt but still real — chemical and electroplating units in Wazirpur facing HSPCB or DPCC discharge notices sometimes need ZLD as the only compliant path when conventional discharge limits can't be met.
Most NCR ZLD enquiries come from units retrofitting an existing ETP that no longer meets tightened discharge norms, rather than new construction.
Key industrial areas we serve in Delhi NCR:
Regulatory Note: The Delhi Pollution Control Committee (DPCC) and CPCB have issued strict norms for all industries and large residential projects in Delhi. Non-compliant units face closure orders. All Optima systems are designed to meet current DPCC and CPCB discharge standards.

Common Questions
Zero Liquid Discharge Plant in Delhi NCR — FAQ
Does every NCR industrial unit need ZLD?
No — ZLD is generally required only for units whose discharge can't meet standard norms even after conventional ETP treatment, such as some electroplating and chemical processing units in Wazirpur. Most units only need standard ETP treatment.
What does a ZLD system cost in NCR?
Cost typically runs ₹40 Lakh to over ₹2 Crore depending on effluent volume and complexity. Call +91 9711880791 for an assessment specific to your process.
Can Optima upgrade an existing NCR ETP to ZLD?
Yes, this is a common project type — we assess the existing system and add the recovery stages needed to reach zero discharge rather than requiring a full rebuild.
How long does ZLD approval take in NCR?
Typically 8-12 weeks given the additional technical documentation HSPCB or DPCC require for recovery systems.
