Our Business / Thermal Power StationsWater Pollution Countermeasures

Wastewater generated by operating the power stations is purified by wastewater treatment facility and released under constantly monitoring with continuous water quality measurement equipment. Also, in order to suppress rising temperature of the seawater used in the condenser, seawater from the deep layer with low temperature is slowly taken and the water is reduced its flow rate be released to the surface of the ocean and such, to reduce the impact on the surrounding environment.

  • Measures to reduce wastewater:
    Water used at the power station is treated in the wastewater treatment facility, and is released as clean water. The wastewater is constantly monitored by the water quality measurement equipment.
  • Measures against warm drainage:
    A curtain wall is installed to take the seawater used in the condenser, and the seawater from the deep layer with low temperature is slowly taken and the water with reduced flow rate is released to the surface of the ocean and such, to reduce the impact on the surrounding environment.
