Purify Wastewater for Reuse with Zero Liquid Discharge (ZLD)
Zero Liquid Discharge (ZLD) is an advanced and cost-effective process that eliminates all effluent discharge from industrial manufacturing. ZLD systems create a closed-loop, separating wastewater from solid byproducts and purifying it for reuse, ensuring no liquid waste enters the environment.

How ZLD Systems Work
ZLD systems treat wastewater and concentrate waste into solid form using specialized processes such as:
- thermische Verdampfung
- Membrandestillation
- Forward and Reverse Osmosis
- Electrodialysis
Core Components:
- Filtersysteme
- Klärbecken und Reaktoren
- Konzentratoren
- Verdampfer
- Kristallisatoren
- Membransysteme zur Umkehrosmose
Process Overview
Each ZLD system operates uniquely, yet the overall treatment process follows a consistent sequence of steps.
Chemicals and pH balancers prepare the waste for processing.
Brine concentrators or electrodialysis condense solids.
Clean water is recovered and redirected for reuse.
Solid waste is dried for disposal or recovery.
Applications of ZLD
ZLD systems are essential for industries striving to minimize environmental impact, reduce water usage, and recover valuable resources.
Key Applications
Here is a summary of key applications that benefit from ZLD systems.
Safely condenses and disposes of radioactive waste solids while reusing water.
Reduces reliance on local water sources by reusing filtered water.
Recovers water for refining while minimizing waste.
Prevents discharge of harmful chemicals into the environment.
Treats acidic wastewater and recovers valuable resources.
Ensures pure water for rinsing, enhancing product quality.
Tailored Treatment Options
While ZLD offers 100% water recovery, many facilities benefit from practical reuse systems achieving 70–85% recovery at lower costs. ZLD is ideal for operations with:
High water demands exceeding available supply.
Poor-quality source water.
Limited options for wastewater discharge.
MacDermid Envio works with you to evaluate your needs and recommend the most efficient, cost-effective solution for your facility.
Why ZLD Matters
ZLD is a critical process for modern industrial wastewater treatment. Let MacDermid Envio help you implement a ZLD system that meets your operational and environmental goals while maximizing efficiency and sustainability.
