Zero Liquid Discharge (ZLD) is a treatment process designed to remove all the liquid waste from a system. The focus of ZLD is to reduce wastewater economically and produce clean water that is suitable for reuse (e.g. irrigation), thereby saving money and being beneficial to the environment. ZLD systems employ advanced wastewater/desalination treatment technologies to purify and recycle virtually all of the wastewater produced.

ZLD plant are called in this way as their common name Zero Liquid Discharge System, Zero Liquid Discharge Plant, zld system, zld plant , zld plant manufactures, best zero Liquid Discharge, best zero Liquid Discharge plant, Zero Liquid Discharge, effluent Zero Liquid Discharge, zero liquid discharge wastewater treatment, zld wastewater treatment, Zero Liquid Discharge wastewater treatment, zld wastewater, ZLD evaporator, zld water treatment, Zero Liquid Discharge.

The power industry as well as oil & gas, chemical, petrochemicals, mining and other industries generate large volumes of waste water that must be managed. Commonly these wastewaters are discharged via a plant outfall to a surface water body, an evaporation pond, or in some cases deep well injected. However, there are growing environmental concerns regarding such discharge practices, which has resulted in the development of Zero Liquid Discharge (ZLD) processes. 

There are several economic drivers for ZLD. A growing concern by the public of the impact of waste water discharge on the environment, and in many areas of the world, water is a scarce resource. Competition for available water supply is increasing steadily. Such concern is resulting in increased regulation and limitation of waste water discharges and at some point, banning them all together. Even without regulatory push, many companies in various industries are mandating initiatives for reducing water discharge by recycle and reuse, as well as zero liquid discharge (ZLD), to reduce their environmental footprint and improve sustainability. 

The Zerusa Liquid Effluent Treatment System (ZLETS) uses proven technology to process the facility's liquid effluents to a high-quality effluent meeting the facility's goals of zero liquid discharge.  The system has been designed to provide a high level of water quality and flexibility in operation over a wide range of expected feed stream conditions to meet the desired future needs of the plant.  Operator safety, equipment reliability, and overall system operation have been key considerations to provide an economical system with long-term viability.
