Zero Liquid Discharge
Total Recovery. No Waste. Just Results.
ZLD Plant often promise more than they deliver.
But poor design leads to high steam use and system inefficiency.
Why? Because the system isn’t designed around real effluent data, it becomes inefficient.
Turn wastewater compliance into a competitive asset with Inovar’s Zero Liquid Discharge (ZLD) solutions. We build reliable ZLD plant that maximize water recovery for reuse and transform waste into solid by-products, helping you meet stringent regulations, reduce freshwater dependency, and lower long-term disposal costs.
What do we do differently?
- We start with lab analysis of your actual effluent.
- Meticulous selection of material .
- We simulate recovery, evaporation, and crystallization before we design.
- We prioritise proper pre-treatment to ease downstream load.
- Each unit RO, MEE/MVR, crystallizer is custom sized to your effluent.
- Our systems are durable, efficient, and easy to run.
- We focus on long-term performance, not just compliance.

Everything you need to know about Zero Liquid Discharge
Looking to fix or upgrade an existing ZLD Plant?
We offer audit-based redesigns. After reviewing your system and testing samples, we help you improve recovery, reduce costs, and simplify operations.
Since 2019, Inovar has been redefining ZLD System
- We design Zero Liquid Discharge systems with recovery data, not guesswork.
- We engineer for high recovery and low waste, not just regulatory compliance.
- We don’t cut corners with oversized evaporators or shortcut chemistry.
- We prioritize lifecycle cost and sustainability, not just CapEx.
- We stay invested long after commissioning with AMC, audits, and performance tracking.
ZLD System Components
Inovar’s Zero Liquid Discharge systems (ZLD Plant) combine multiple advanced technologies to recover, purify, and solidify every drop of wastewater leaving behind no liquid discharge.
- Ultrafiltration (UF) - Removes suspended solids, organics, and bacteria protects downstream RO membranes.
- Reverse Osmosis (RO) System - Concentrates dissolved salts and recovers up to 75–85% of clean water.
- Desalination Unit - Treats high-salinity brine or seawater to produce process-grade water.
- Evaporators - Further reduces RO reject by evaporating the remaining water, converting it into condensate for reuse.
- Crystallizer - Solidifies dissolved salts from the evaporator reject, enabling safe disposal or reuse of solids.
- Sludge Handling System - Collects and dewaters sludge for safe, compliant disposal.
Frequently Asked Questions
What is a Zero Liquid Discharge system (ZLD Plant)?
A ZLD system recovers and reuses all wastewater, ensuring no liquid is released into the environment.
Why is ZLD Plant important?
It conserves water, prevents pollution and meets strict industrial discharge regulations.
How does a Zero Liquid Discharge system work?
It combines pre-treatment, membrane filtration and evaporation to recover water and convert waste to solids.
Which industries need ZLD Plant?
Pharma, textile, electroplating, power and chemical industries where effluent discharge is restricted.
Can existing ETP or RO systems be upgraded to ZLD?
Yes, Inovar integrates additional recovery and evaporation units into existing infrastructure.
What happens to the salts and sludge generated?
They are collected, dewatered, and disposed of as per hazardous waste guidelines.
How much water recovery is possible?
Typically 90–95% of wastewater is recovered as reusable clean water.
Is ZLD Plant expensive to operate?
With optimized design and energy-efficient processes, Inovar significantly reduces OPEX and maintenance costs.
Can treated water be reused in the plant?
Yes, the recovered water can be reused for cooling, washing or process applications.
How does Inovar ensure reliable ZLD Plant performance?
By balancing biological, chemical and thermal stages to maintain consistent recovery and compliance.
