What we want to do:

The project aims to recycle volatile substances contained in wastewater. The proposed process, which combines conventional chemical engineering operations with membrane technology, will achieve both higher effluent purity and valuable recycled and marketable products, in addition to reducing the amount of waste disposed of in landfills or discharged into the atmosphere. The project focuses primarily on the treatment of wastewater containing recyclable dissolved salts. This can include polluted seawater, brackish water, digestate, rainwater leachate from landfills, industrial and agricultural wastewater, wastewater from wastewater treatment plants or biogas plants. To achieve its objectives, the project uses, among other things, a system of porous and non-porous thin-walled hollow capillaries (fibres) as part of a complex technology which, although currently being developed in membrane processes, is still relatively little used in practice. Fibre bundles can be used both for separating desired salts from solutions themselves and for revitalisation steps in wastewater treatment. The potential of this type of membrane technology is enormous, both in terms of the efficiency of the separation processes and in terms of low investment and, more importantly, operating costs and the possibility of application in diverse fields. As an example of the proposed technology, the process of reducing the problematic ammonia content contained mainly in wastewater from agricultural production, in the sludge water of water treatment plants or in fugates discharged from biogas plants, associated with the conversion of separated ammonia into ammonia salt, which finds application in agricultural production as a desired targeted nitrogen fertiliser, can be presented.
