Definition - What does Service Water mean?
Service water is water that does not meet 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 it use, such as:
Service water reduces corrosion of equipment and lessens overhead cost.
Corrosionpedia explains Service Water
Service water is treated water which is used for specific purposes, such as preparatory processing phases or industrial purposes. Typical applications include:
- Supplying thermal power stations and petrochemical plants with coolant water
- Water for fire extinguishing systems
- Cleaning of machinery
Service water of an appropriate quality is taken from the corresponding point in the water treatment plant for its specific use.
For service water, during treatment the following methods can be employed combined or alternately:
- Full and partial desalination by softening
- Reverse osmosis
- Ion exchange
- Thermal desalination
Industrial operations need various water qualities for differing applications, such as:
- Process water for direct use in production
- Boiler feed water and treated condensate for boiler plants
- Supplement in cooling towers
- General purposes
In nuclear reactor safety systems, the essential service water system (ESWS) circulates the water that cools the plant’s heat exchangers and other components before dissipating the heat into the environment.
