Zero Liquid Discharge (ZLD)

Zero Liquid Discharge (ZLD) is a water treatment process designed to eliminate any liquid waste from a facility by recycling and reusing water continuously. In ZLD systems, wastewater is thoroughly treated to remove contaminants, and almost all water is recovered for reuse, leaving only solid residues or sludge. This approach minimizes water consumption and prevents pollution, making it ideal for areas with scarce water resources or strict environmental standards. Essentially, ZLD ensures that no liquid waste is discharged into the environment, promoting sustainable and responsible water management.
