Zero Liquid Discharge System

Zero Liquid Discharge (ZLD) is a treatment process that its goal is to earn more remove all the liquid waste from a system. The focus of ZLD is to reduce economically wastewater and produce clean water that is suitable for reuse, thus saving money and being beneficial to the environment. ZLD systems employ the most advanced wastewater treatment technologies to purify and recycle virtually all of the wastewater produced.

What is a zero liquid discharge system?

12.8 Zero liquid discharge. 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.

What are the benefits of ZLD?

The main benefits of ZLD are: Minimizes wastewater discharge. Maximizes water recovery. Creates a valuable product for sale and further processing.
