Chemical free makeup water for power plant

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.
