Optima Water Solutions is a ZLD Plant Supplier in Surat. 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 Surat — Why It Matters
Surat's textile-dyeing industry makes it, alongside Ahmedabad, one of the highest-ZLD-demand cities we serve — GPCB's norms for this sector given the sheer scale of processing volume concentrated here mean ZLD is close to a default requirement for dyeing units.
Diamond processing units generally don't need ZLD given their different effluent profile, distinguishing Surat's two dominant industries sharply in this respect.
Key industrial areas we serve in Surat:
Regulatory Note: GPCB has specific norms for Surat's massive textile and diamond processing industries. ZLD norms apply to dyeing and processing units.

Common Questions
Zero Liquid Discharge Plant in Surat — FAQ
Do all Surat textile units need ZLD?
A large share of dyeing units in GIDC Surat, Pandesara, and Kadodara fall under GPCB's ZLD mandate given the scale of textile processing concentrated in the city.
What does a ZLD system cost in Surat?
Given the multi-stage treatment textile effluent requires, cost typically runs ₹60 Lakh to over ₹2.5 Crore. Call +91 9711880791 for an assessment specific to your process.
Do Surat diamond processing units need ZLD?
Generally no — diamond processing effluent has a different profile than textile-dyeing effluent and typically doesn't require the same zero-discharge treatment.
How does Optima's Surat experience inform ZLD design?
Given the volume of textile-dyeing ZLD projects we've delivered in Surat, we bring substantial process-specific design experience to new clients in the sector.
