Optima Water Solutions designs and installs Zero Liquid Discharge (ZLD) Plants in Delhi NCR, enabling industries to achieve complete elimination of liquid effluent discharge. Mandatory for textile, distillery, sugar, tannery, and other industries under CPCB ZLD mandates, our ISO 9001:2015 certified systems combine advanced membrane technology with thermal evaporation to recover maximum water and produce dry solid waste only.
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
Delhi NCR is India's largest urban agglomeration and one of the most industrially active regions in the country. The Delhi Pollution Control Committee (DPCC) and Haryana / UP State Pollution Control Boards enforce strict effluent discharge norms for industries and commercial establishments across the NCR region.
Growing demand from residential townships in Noida, Gurgaon, Greater Noida, Faridabad, and Ghaziabad has created significant need for Zero Liquid Discharge Plant solutions in the NCR region. Optima Water Solutions is headquartered in Delhi NCR — giving our clients the fastest response times, lowest logistics costs, and dedicated local support compared to any other vendor.
From industrial estates in Okhla and Wazirpur to residential societies in Dwarka and luxury townships in Gurgaon, we have installed and commissioned systems across the entire NCR belt.
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
What is the cost of a Zero Liquid Discharge Plant in Delhi NCR?
ZLD plant cost in Delhi NCR varies significantly based on effluent volume and characteristics. A 5 KLD ZLD system starts from ₹30–50 Lakh. A 50 KLD ZLD plant typically costs ₹1.5–3 Crore. Textile dyeing ZLD systems for 100 KLD+ can cost ₹3–10 Crore. Contact Optima for a free feasibility assessment and budgetary quote.
Is ZLD mandatory for my industry in Delhi NCR?
ZLD is mandatory for textile dyeing/processing, distilleries, sugar mills, tanneries, pharmaceutical bulk drug, dyes and dye intermediates, and chlor-alkali industries in India. The Delhi PCB may have issued ZLD notices to your category. Optima can review your industry category and advise on compliance requirements in Delhi NCR.
How much water is recovered in a ZLD plant?
A well-designed ZLD plant recovers 90–95% of the input water volume for reuse in your process. Only 5–10% ends up as concentrate which is then evaporated to dry solids. This dramatically reduces your fresh water intake and eliminates liquid discharge completely.
What is the difference between ETP and ZLD?
An ETP treats effluent to meet discharge standards and the treated water is discharged to the drain or river. A ZLD plant goes further — it recycles all treated water back to your process with zero discharge to any water body. ZLD requires additional RO and evaporation stages beyond a standard ETP.
Can you upgrade our existing ETP to ZLD in Delhi NCR?
Yes. This is the most common ZLD project Optima handles. If you have an existing ETP in Delhi NCR, we add RO, MEE/MVR, and an ATFD or spray dryer to convert it to full ZLD. We assess your current ETP and design the most cost-effective upgrade path to achieve compliance.
