Zero Liquid Discharge Plant for Food Industry

Why ZLD for the Food Industry?

Food and beverage manufacturing generates complex wastewater containing organic matter, fats, oils, grease (FOG), and dissolved solids. A ZLD system ensures that no untreated liquid is released into the environment—supporting both sustainability goals and legal compliance.

ZLD System Process Overview:

1. Wastewater Characterization:
   Detailed analysis of wastewater for pH, BOD, COD, TSS, and contaminants.

2. Collection & Segregation:
   Organized capture and separation of process water, cleaning water, and effluents.

3. Pretreatment:
   Removal of solids, FOG, and other physical contaminants to protect downstream units.

4. Biological Treatment:
   Aerobic or anaerobic systems break down organic pollutants effectively.

5. Advanced Filtration:
   Use of Ultrafiltration (UF) and Reverse Osmosis (RO) to purify water and concentrate waste.

6. Evaporation & Crystallization:
   Final concentration of brine followed by crystallization to recover or safely dispose of salts.

7. Brine & Sludge Management:
   Safe disposal or recovery of solid by-products in line with environmental regulations.

8. Heat Recovery:
   Energy-efficient operation through integrated heat recovery systems.

9. Monitoring & Automation:
   Continuous monitoring and smart control systems ensure stable performance and compliance.
