Optima Water Solutions is a ZLD Plant Supplier in Bengaluru. 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 Bengaluru — Why It Matters
ZLD demand in Bengaluru is limited given the city's IT-dominant economy, but does exist among select chemical and electronics manufacturing units in Peenya facing stricter KSPCB discharge requirements.
Given how few Bengaluru units genuinely need ZLD, we assess this carefully rather than recommending it where standard ETP treatment would suffice.
Key industrial areas we serve in Bengaluru:
Regulatory Note: Karnataka State Pollution Control Board (KSPCB) mandates STPs for large residential projects and ETPs for all category industries in Bengaluru.

Common Questions
Zero Liquid Discharge Plant in Bengaluru — FAQ
Do Bengaluru electronics units typically need ZLD?
Most don't — ZLD is generally reserved for units whose effluent characteristics genuinely can't meet KSPCB discharge limits through conventional treatment. We assess this before recommending it.
What does a ZLD system cost in Bengaluru?
Cost typically runs ₹40 Lakh to over ₹2 Crore depending on effluent complexity. Call +91 9711880791 for an assessment specific to your process.
How does Optima decide if a Bengaluru unit needs ZLD versus standard ETP?
We review your specific effluent characteristics and KSPCB category — ZLD is only proposed where standard treatment genuinely can't achieve compliant discharge.
Which Bengaluru industries most commonly need ZLD?
Select chemical processing and some specialty electronics manufacturing units in Peenya, where discharge limits are particularly strict.
