Partner offer (competences/expertise)
IRIS is connected to a network of research and industry partners each offering advanced water treatment technologies suited to treat industrial/domestic water with recalcitrant, difficult to treat pollutants and microbial contamination at a small scale. The treatment technologies available include:
• direct electric discharges in water and other advanced oxidation processes for water sterilisation,
• advanced photocatalysis to enhance the biodegradability of emerging and recalcitrant pollutants,
• nanofiltration to retain most of the common organic pollutants and to reduce the concentration of polyvalent ions in water,
• solar-photo-Fenton-AOP used to completely mineralize the organic pollutants,
• photocatalytic nanoporous adsorbent module e.g. for removal of mixtures of different dyes,
• microwaves for the removal of persistent organic pollutants.
Each technology is developed in modules that can be combined to best suit the type of pollution and the expected level of water purity requested as output, with recovery of valuable compounds where possible.
The ideal application of our suite of technologies is the use of alternative sources of water. Mains water is often of higher standards than required by the users (e.g. drinking water for washing of non-food plants), so it is over engineered. Often, other sources of water are available locally, be it collected rain water, wastewaters from nearby users (e.g. grey water from domestic use), small wells, water too expensive to treat in large volumes, like brackish waters. Furthermore, in a symbiotic approach, other water users are available and might be able to use any waste water that might not be recyclable within the plant, including agriculture. So there is an opportunity not only to seek out the closest water source to be treated exactly right for the needs but also the closest user of those water flows that cannot be used internally. In an integrated water management, wastewater can be treated to become the feed of a nearby factory or as irrigation water, while respecting the current regulations and standards.
The ideal test ground and demonstration pilot that we are searching for is a cluster of companies located in the same area, an industrial or commercial complex, or even a small city district where the water resources are used for different applications and where the water used for one application could be treated and re-used for a different purpose. For example, cooling water from a biomass power plant could be used by a nearby industrial laundry; organic compounds rich (or enriched through concentration processes) water would benefit local cultivations providing both nutrients and irrigation.
