Systems Concept for Wastewater Reuse

Reuse of treated wastewater, e.g. for irrigation or as service water, saves water and power for its supply. This is particularly the case where:

  • water is in short supply and has to be produced by expensive and power consuming processes; e.g. power consumption of desalination is around  4.0 kWh/m³.
  • water is supplied from far away; e.g. power consumption of water supply in Southern California is 2.3 kWh/m³.
  • water is produced from surface water with a power consumption of 1 – 2 kWh/m³.

Costly and energy consuming nutrient removal is usually not desired. Nutrients add value to irrigation water.

Wastewater treatment processes depend on the required reuse water quality. In some cases mechanical/chemical treatment (See HUBER MeChem® Solutions) is sufficient while in other cases excellent effluent quality of membrane bio-reactors (MBR) is required.

HUBER ReUse Solutions offer a wide range of options.
