Removal of carbon dioxide from RO-water
The MDU SACP is an advanced, chemical-free degassing solution engineered as an add-on for reverse osmosis units. Operating solely on air sweep, it eliminates the need for chemicals in the degassing process—reducing operational costs and removing hazardous substance handling. Its compact, energy-efficient design integrates seamlessly into both existing setups and packaged solutions, while the modular construction ensures flexible installation across a wide range of applications.
Harnessing the advantages
The MDU SACP provides a compact and efficient solution for removing CO₂ after the reverse osmosis (RO) unit and before the EDI unit (or mixed bed). This process reduces chemical consumption, enhances EDI performance, and - by lowering CO₂ levels - also improves silica removal.

Chemical-free make-up 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 to achieve very low conductivity and silica content.
