Aars District Heating plant is a modern combined heat and power plant that primarily uses waste as fuel. More than 5,400 households, corresponding to approx. 98% of the total heat demand in the local area benefits from the environmentally friendly district heating.
It is of great importance for a good district heating operation that the piping network from the heating plant to the individual consumer is in order. If the water, which transports the energy around and heats the houses, does not have the right water quality, there is a great risk of eg. breakdown and loss of valuable energy.
Aars District Heating plant has upgraded their water treatment plant so that the water quality is without salts and oxygen. In other words, optimum corrosion prevention for the distribution network as well as the technical installations.
The membrane unit for reducing the water's salt content is optimized with respect to water utilization. A unit of the type RO-PLUS has been selected.
Oxygen is removed in a membrane degassing unit, which, in line with the rest of the solution, is based on a chemical-free technology.
- Flow: 5.5 m3/h
- Conductivity: <10 µS/cm
- Oxygen: <20 ppb
