Zero Liquid Discharge Plant for Pharmaceutical Industry

How Our ZLD System Works

1. Wastewater Characterization & Segregation

   • Identification of pH, solvents, contaminants, and APIs

   • Segregation of process streams to avoid chemical incompatibility

2. Pretreatment

   • Removal of coarse solids, oils, and greases to protect downstream components

3. Solvent & Chemical Recovery

   • Integration of solvent recovery units to reclaim valuable materials and reduce waste treatment costs

4. Biological Treatment (if applicable)

   • Aerobic or anaerobic systems break down biodegradable organic matter

5. Advanced Filtration

   • Ultrafiltration (UF) and Reverse Osmosis (RO) to separate dissolved solids, salts, and trace solvents

6. Evaporation & Crystallization

   • Final treatment of RO reject through thermal systems to extract pure water and leave behind dry solids

7. Brine & Solid Waste Management

   • Safe disposal or potential reuse of salts and other residuals, compliant with environmental standards

8. Energy Optimization

   • Heat recovery systems are integrated to reduce operational costs and improve energy efficiency

9. Automation & Monitoring

   • Real-time system control ensures stable performance, safety, and regulatory compliance

Benefits of ZLD for Pharma Industry

• 100% elimination of liquid effluent discharge

• Helps meet CPCB/SPCB and MoEF compliance

• Recovery of water, solvents, and chemical compounds

• Reduced operational risks and environmental footprint

• Demonstrates leadership in ESG and sustainability goals
