Zero Liquid Discharge

Turn waste into value with an Alfa Laval ZLD system. These robust, compact solutions treat wastewater from industrial processes and recover valuable products during recycling operations. Materials are efficiently removed from the water, or wet material, and reduced to solid waste that can be sold, reused, or more efficiently disposed of. ZLD systems benefit both the environment and your bottom-line and are easily adjusted to meet your expanding needs and changing regulations.

Zero liquid discharge

Smart solution to reclaim resources and minimize waste volumes

  • Increases water usage efficiency by removing liquid waste and treating water for reuse
  • Some processes may recover valuable resources such as metals and minerals
  • Easily adjustable systems are future-proof to your growing needs and changing regulations
  • Less waste means lower disposal costs and reduced need for new resources
  • Lower investment, installation and operational costs compared to traditional evaporation technologies

Effectively dealing with industrial wastewater is often a legal obligation, and necessary to retain your license to operate. But an Alfa Laval ZLD system can be a part of the process of recovering valuable resources from the waste that would have been lost. Alfa Laval’s product offering and technology expertise can play a key part in your resource recovery process.

A choice of configurations

Mechanical vapor recompression (MVR)

Alfa Laval ZLD systems can be designed with MVR using electrical power to drive the evaporation process. An electrically driven fan increases the condensation temperature of the vapor in the evaporator before it is routed back to the heat exchanger where the latent heat is recovered. This configuration is ideal when there is no thermal heat source and when boiling point elevations are moderate.

Multi-effect systems

Alfa Laval ZLD systems can be designed using a thermal heat source such as steam or hot water, with one or several effects depending on the capacity requirements and your energy efficiency targets. The configuration is ideal when thermal heat sources are available and is generally more attractive in terms of capital expenditure.
