Progress report for
By-products from steel industry for water purification.
Achievement at a glance
Hgans AB has continuously worked with the side-stream materials (e.g. mineral-based by-products) with the objective to make them useful for different applications instead of being treated and handled as waste. This also includes upgrading of these materials into high value applications. In the area of water purification through the use of slags from steel industry, a spectrum of different technologies including mechanisms for these processes have been investigated and studied within the Swedish research project Minrent, where Hgans takes an active part.Since 2018, in the area of water purification with steel slags as filter media several long-term field trials have been carried out. The results so far are in general very successful and the interest for using steel slags as filter media is high both from end-users and from companies in the area of water purification. Even if the outcome from these trials in general is successful, there are some variations in results that are difficult to understand and explain. This in turn demands more activities and evaluations before it is possible to make the transition from pilot scale operations to industrial scale and put the material on the market. Keeping this in mind, we foresee that the end date of this project will be postponed with one year approximately.
