97. ZERO LIQUID DISCHARGE (ZLD)

♤ Zero Liquid Discharge is a process that is beneficial to industrial and municipal organizations as well as the environment because money is being saved and no effluent, or discharge, is left over.

♤ ZLD systems employ the most advanced wastewater treatment technologies to purify and recycle virtually all of the wastewater produced.

♤ Zero Liquid Discharge System ZLD systems provide numerous economic and environmental advantages for plant managers—water is recycled and reused, saving on the cost and treatment of raw water.

♤ Since all water is reclaimed, no effluent is discharged from the plant, avoiding the cost of environmental impact.

♤ The technology is particularly appropriate in water-short areas.

Zero Liquid Discharge Technologies for Water Recycle Reuse Applications:

♤ Biological Treatment Systems

♤ Physical/Chemical Treatment Systems

♤ Conventional Filtration Systems

♤ Membrane Filtration and Separation Systems

♤ Chemical Feed and Disinfection Systems
