Zero Liquid Discharge

Alfa Laval ZLD systems are robust compact solutions for absolute minimization of liquid discharge in industrial waste applications. Highly adaptable, they can be used across a range of demanding duties in various industries for wastewater reduction as well as recovery of product, and of water suitable for reuse. Our proven track record and extensive experience in both thermal solutions and separation technology ensure a cost-efficient solution.

Reuse water, recover value with ZLD 604x360

Smart solution to reclaim resources and minimize waste volumes

  • Low investment, installation and operational costs
  • Special heat exchanger plate design minimizes fouling and scaling
  • High efficiency reduces heat transfer area required
  • Can operate cost effectively at vacuum thereby reducing scaling risks
  • Cost-effective maintenance – 100% cleanable and inspectable heat transfer surfaces

Alfa Laval ZLD systems combine our proven plate evaporator and decanter centrifuge technology. The evaporation systems work in a forced circulation mode, with flashing occurring inside the cyclonic vessel. In standard configuration, the system has an evaporation capacity up to 100 m3/hr and results in more than 90% crystal dewatering. each system can be adapted to the specific separation duty and capacities.

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.
