Oxygen Removal From Feedwater In A Central District Heating System

Source: 3M Separation and Purification Sciences Division

In central district heating systems, heated water from power plants is distributed to densely populated areas via insulated piping networks. High water quality is required to maintain the integrity of pipes, storage tanks, and other infrastructure in such systems. This case study explains how a Dutch power station achieved an O2 specification of <10 ppb for storage water tank filling by installing a chemical-free deoxygenation system.
