water utilities are becoming increasingly interested in central drinking water
softening. The Greater Copenhagen utility HOFOR is currently implementing
pellet softening and Tårnby Forsyning is currently implementing ion exchange.
More utilities are expected to follow during the next years.
Environment we are a research group working with drinking water softening and
the challenges that arise when implementing this new process. Among the topics
we work with are:
- Effects from central softening in
households and in industry (e.g. lime scaling, consumption of detergents and
lifespan of appliances)
- Effects from softening on
microbiology in rapid sand filters
- Optimization of the softening
process (e.g. choice of softening
chemical and seeding material)
- Reuse of by-products from softening
(mainly calcium carbonate pellets)
We offer the opportunity for student projects within the fields described above
or other topics related to softening, if you have a good idea. Depending on the
project topic and focus, it will be possible to do the project in collaboration
with HOFOR or another utility company.
Feel free to contact us and find out if we have
a project that matches your interests.
