Optima Water Solutions designs and installs Zero Liquid Discharge (ZLD) Plants in Canada, 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 Canada — Why It Matters
Environment and Climate Change Canada (ECCC) enforces CEPA effluent regulations. Pulp and paper, oil sands, and mining industries face strict ETP requirements. Provincial environmental standards vary and can exceed federal minimums. This makes properly designed ZLD systems essential for operators in Canada, particularly around Greater Toronto Industrial, Fort McMurray Oil Sands, Montreal Port Industrial.
Optima Water Solutions supports clients in Canada with end-to-end ZLD project delivery — from design and manufacturing to installation, commissioning, and long-term AMC support.

Common Questions
Zero Liquid Discharge Plant in Canada — FAQ
What is the cost of a Zero Liquid Discharge Plant in Canada?
ZLD plant cost in Canada 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 Canada?
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 Canada PCB may have issued ZLD notices to your category. Optima can review your industry category and advise on compliance requirements in Canada.
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 Canada?
Yes. This is the most common ZLD project Optima handles. If you have an existing ETP in Canada, 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.
