Zero Liquid Discharge (ZLD) Plant Design
Zero Liquid Discharge systems ensure no liquid effluent leaves your plant boundary — the most stringent standard in industrial wastewater management. SMRS Infra designs ZLD systems that are technically sound, cost-optimized and compliant with environmental regulations.
The Most Stringent Standard in Wastewater Management
Zero Liquid Discharge is now a regulatory requirement across many industrial sectors in India and internationally. Achieving ZLD compliance requires a treatment train that takes high-strength effluent all the way through to a dry solid — with no liquid discharge at any point. The design challenge lies in technology selection, energy optimization and integration across multiple treatment stages. SMRS Infra brings specialist ZLD process design expertise, having worked across the industries most affected by ZLD mandates: textiles, pharmaceuticals, chemicals and power.
