ZLD technologies (zero liquid discharge) and MLD (minimum liquid discharge) for industrial applications

Zero liquid discharge (ZLD) is a strategic wastewater management system that ensures that there will be no discharge of industrial wastewater into the environment. It is achieved by treating wastewater through recycling and then recovery and reuse for industrial purpose

The technologies used to achieve Zero liquid discharge include ultrafiltration, reverse osmosis, evaporation/crystallization, and fractional electrodeionization.
