A Zero Liquid Discharge (ZLD) system involves a range of advanced waste water treatment technologies to recycle recovery and reuse of the treated waste water and thereby ensure there is no discharge of waste water to the environment.

A typical ZLD system comprises of the following components:

• Pretreatment (Physico-chemical & Biological)
• Reverse Osmosis (Membrane Processes)
• Evaporators & Crystallizer (Thermal Process)

Efficient, innovative management of entire water cycles for industrial applications are heading towards Zero Liquid Discharge(ZLD), allowing business to save money, reduce environmental impact and meet pollution discharge.

Achieving stringent waste water treatment regulations and reducing water usage have become one of the most critical considerations in industry today. Numerous environmental regulations, rigorous permitting process and lack of water availability, amount other factors, are driving many industrial facilities to implement Zero Liquid Discharge (ZLD) system as a solution.

In many cases, your plant water consumption can be reduced by up to 90% - saving money and helping to save the environment. WEI can able to provide comprehensive portfolio of technologies for ZLD applications, including brine concentrators, evaporators and crystallizers.

ZLD equipment's, such as ultrafiltration's (UF), reverse osmosis (RO) and evaporators to provide the optimal solution. Our specialists can tailor a system to fit your waste water characteristics, flowrates, and end products requirements.

ZLD evaporator systems for concentrating liquid waste streams allow you to recover distilled water from waste streams.

Crystallizing system for ZLD reduce waste water discharge and in many cases can allow you to capture valuable by products. Typically an evaporator or RO( Reverse Osmosis system is used to pre concentrate waste water. Crystallization or evaporation then produces water for reuse as well as recovering specific salts that are suitable for disposal or resale to offset plant costs. We also provide part & service on all of our equipment, as well as equipment which may have been provided by other manufacturers.
