Zero Liquid Discharge Plant for Chemical Industry
A Zero Liquid Discharge (ZLD) Plant for Chemical Industry is a complete wastewater treatment system designed to ensure 100% recycling of effluent with zero discharge to the environment. At Green Aqua Technologies, we provide advanced ZLD systems that help chemical manufacturing units reduce water pollution, comply with government norms, and achieve sustainable water recovery. Our solutions are engineered for high TDS, high COD wastewater and guarantee long-term performance.
What is a ZLD Plant for the Chemical Industry?
A ZLD plant is an integrated system that treats, recycles and reuses wastewater generated from chemical processing units. Instead of releasing effluent into rivers or land, the plant recovers clean water and converts dissolved solids into dry, manageable salts. For chemical industries where effluent is highly contaminated, ZLD ensures safe, eco-friendly and regulatory-approved disposal.
Why Do Chemical Industries Need ZLD Systems?
Chemical plants generate wastewater containing toxins, acids, dyes, solvents, heavy metals and organic pollutants. A ZLD system helps them:
- Meet CPCB & Pollution Control Board discharge norms
- Prevent soil & groundwater contamination
- Reduce fresh water consumption
- Improve environmental sustainability
- Protect brand image and compliance certifications
How Does Zero Liquid Discharge Plant Work?
A typical ZLD system by Green Aqua Technologies includes:
- Pre-Treatment- This step removes suspended solids, oils and basic contaminants to protect downstream equipment.
- RO System (Reverse Osmosis)- RO helps recover maximum reusable water by separating high-TDS salts from clean permeate water.
- Multiple Effect Evaporator (MEE)- The evaporator concentrates the RO reject, reducing the liquid volume significantly.
- ATFD / Dryer System- Agitated Thin Film Dryer (ATFD) converts concentrated brine into dry solid salts for safe disposal.
- Condensate Polishing- The recovered condensate is treated further to achieve high-quality reusable water for process use.
