Environmental impact from drinking water softening technologies

Several Danish utilities are currently implementing centralised drinking water softening. In areas with hard drinking water, softening can provide a number of positive socioeconomic and environmental effects experienced by the end users (households or industries) due to reduced problems with lime scaling, a longer service life of household appliances and installations, and reduced of soap and detergents.

 Different softening technologies exist including e.g. pellet softening, ion exchange and membrane filtration. The technologies vary in terms of chemical use, energy use and water loss. Despite the potential environmental benefits from drinking water softening, the environmental impact from the different softening technologies is rarely considered from a life cycle perspective when choosing softening technology.

This project aims at comparing different softening technologies and the effects experienced by the end users using life cycle assessment alone or in combination with eco-efficiency where environmental assessment is combined with an economy analysis. The risk related to chemical management may also be included.This will provide a better understanding and basis for choosing the optimal softening technology, ultimately leading to a more sustainable implementation of drinking water softening.  

 

Forudsætninger

Relevant bachelor degree. Previous work with life cycle assessment is an advantage
