Chemical free makeup water for power plant

Reference ID: 095103
Industry: Heat and power plants
Application: Boiler water, District heating water

Renosyd I/S, waste-to-energy heat and powerplant located in Skanderborg in Denmark has replaced their existing water treatment plant for make-up water. One of their main concerns was to avoid the use of chemicals. By using a membrane degasser to remove CO2 instead of dosing lye, and by using EDI for producing deionate instead of a conventional mixed-bed, no chemicals are needed for producing deionate water with a very low conductivity and silica content.

Technical data

  • Flow rate: 3.8 m³/h
  • Conductivity: < 0.1 µS/cm
  • Silica (SiO2;): < 20 ppm

 

Units in plant

  • Softening unit SMH 602 with SE20 control panel
  • Reverse osmosis unit B2-16 SE30
  • Membrane degassing unit Liqui-Cel X50
  • EDI unit 1-3400e
  • Mixed bed unit EUREX 601
