Zero Liquid Discharge Solutions

Veolia can aid in the design and implementation of effective ZLD treatment

Fresh water scarcity and concerns for environmental impact resulting from industrial wastewater discharges place a high degree of importance on recycling and reuse of water, an increasingly valuable resource.


As regulatory issues, environmental sensitivity, and long term water supply concerns increase, many industrial companies are considering ways to reduce their water discharges with Zero Liquid Discharge (ZLD) technology.

Veolia is the ZLD plant supplier of choice for many industrial clients.  Veolia has decades of innovation using evaporation and crystallization technology in many wastewater treatment applications including industry experience in volume reduction and ZLD solutions:

  • Power Generation (fossil and nuclear fuel)
  • Oil & Gas field produced water (conventional and unconventional)
  • Oil & Gas Refining
  • Chemical Processing and Manufacture
  • SAGD (Steam Assisted Gravity Drainage, EOR)
  • Mining and Ore Processing
  • Industrial and Municipal Landfill

Veolia has the expertise to design and build wastewater reduction and ZLD solutions of any size, anywhere in the world. Delivery of a project on a lump-sum, turnkey basis ensures that customers have a single point of responsibility. Veolia also specializes in the operation and maintenance of the industrial ZLD plants for a fixed term. 

Process Experience for a Variety of Effluent Streams

Each effluent stream presents its own unique challenge when designing an entire ZLD plant process to efficiently and effectively minimize waste or eliminate the discharge of wastewater. by using zero water discharge technology
