Zero Liquid Discharge Plants (ZLD’S)

Zero Liquid Discharge Plants (ZLD'S)

A Zero Liquid Discharge (ZLD) System involves a range of advanced wastewater treatment technologies to Recycle Recovery and Re-use of the ‘treated’ wastewater and thereby ensure there is no discharge of wastewater to the environment.

A typical ZLD system comprises of the following components:
1. Pre-treatment (Physico-chemical & biological)
2. Reverse Osmosis (Membrane Processes)
3. Evaporators & Crystallizer (Thermal Process)
Efficient, innovative management of entire water cycles for industrial applications are heading
towards Zero Liquid Discharge (ZLD), allowing businesses to save money, reduce
environmental impact and meet pollution discharge

Achieving stringent wastewater treatment regulations and reducing water usage have become one of the most critical considerations in industry today. Numerous environmental regulations, rigorous permitting processes, and lack of water availability, among other factors, are driving many industrial facilities to implement zero liquid discharge (ZLD) systems as a solution.

Key Benefits of ZLD

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

Crystallizing systems for ZLD reduce wastewater 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 wastewater. 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.
