The main message of the recommendations is to use demineralized and oxygen free feed water and thereby avoid chemicals for binding oxygen. It matches the reputation of sustainability in Danish district heating and avoids the handling of chemicals and the issues associated with that. Optimum water treatment ensures a long life cycle for pipes, valves, heat exchangers and fittings.
Membrane degasser: Chemical free oxygen removal
A very efficient solution is membrane degassing. A space efficient technology for removal of oxygen and CO₂ contents in water. The technology is environmentally friendly, uses no chemicals and no maintenance. Read more about membrane degassing here.
By removing oxygen from the feed water you remove the conditions for corrosion of the circuit pipes and technical installations, thereby avoiding disruptions and extending the life time of both pipes and components significantly.
