Service Water is water different from drinking water quality standards. It is mainly used in resource-intensive industries. Depending on the application, the service water must be treated according to the requirements of its use, such as:

  • Commercial
  • Industrial
  • Agricultural
  • Domestic

We can provide customised solution for Service Water using the following method or combination of it;

  • Filtration
    Hitachi Aqua-Tech uses different filtration process to produce service water. 
    Multimedia and activated carbon filtration process reduce the particulate, turbidity, chlorine, organic compounds and a variety of contaminants.
  • Reverse Osmosis
    Service water can be produced from different sources.  Hitachi Aqua-Tech offers Seawater RO System, Brackish Water RO System or Membrane Bioreactor RO System to suit the specific source of water used. 
  • Desalination by Softening
    Softening is the removal of calcium, magnesium and certain metal cations in hard water. Hard water can cause build-up in pipes that impedes water flow. Hitachi Aqua-Tech uses Ion Exchange Resins and Nano Membrane methods in producing service water by softening.


Typical application of service water include:

  • Water for cooling tower in thermal power stations and petrochemical plants
  • Water for fire-fighting systems in industrial plants
  • Cleaning of machineries
  • Domestic use for plant irrigation or household
