Fuel fired power generation plants have several oil storage tanks for feeding fuel to the power units. Coal or gas fired power generation plants also have oil storage tanks to be used for start-up or as a back-up energy source. All power generation plants need to detect oil leaks into storm water, cooling water and condensate.
Hydroelectric power generation plants are usually located in clean nature sites, which have very high environmental protection standards. Large volumes of water are used for generating power as well as for cooling purposes.
How to control the sumps' outlet valve to prevent oil from being discharged into storm water drains or rivers.
High Maintenance cost due to oily water passing through to WWTP.
Late to control upset in the water treatment process and the amount of discharged oil exceeds the permitted level.
Late recovery time the upstream drainage canals and late warning of oil presence.
To monitor underground sumps for any oil/coolant leaks from transformer substations
To monitor water quality at cooling water from lubricating oil leaked from turbine bearings.
Leakwise ID-225 Oil Thickness Monitor can measure the oil thickness for manual skimming or automatically activate a skimming pump.
Leakwise ID-223/HT Oil Sheen Detector installed in a condensate tank with atmospheric pressure can detect an oil sheen in high temperature condensate water.
The Leakwise ID-223 Oil Sheen Detector can be used as an alternative (or as a back-up) on-line monitor which will set off an alarm in case of oil sheen detection, indicating that there is an upset in the water treatment process and the amount of discharged oil exceeds the permitted level.
Leakwise ID-223 Oil Sheen Detectors are installed in oil and storm water collecting sumps, and separators/interceptors located near the dykes or the tanks.
