Invitation to Acquire a Licence to the R&D Results: “Domestic Water Retention Technologies”

Wrocław University of Science and Technology invites interested parties to acquire a paid, non-exclusive licence to use the R&D Results of the Solution developed within Project 86/21/PU “Domestic Water Retention Technologies”, run by the National Centre for Research and Development (NCBR).

About the Solution

The main research problem of the Project was to develop a technological system layout that makes it possible to use treated and disinfected rainwater for washing, laundry and cleaning, and treated domestic wastewater for flushing toilets and watering greenery. As a result, consumption of mains water is reduced.

An element of the system is a monitoring and control application. It enables easy operation of the system, shows the weather forecast for the next 7 days, and displays messages about upcoming rainfall and possible failures.

Diagram description. The system has three inputs: rainwater, grey wastewater and black wastewater. Rainwater goes to a buffer, then to an EOP unit (evaporative liquid treatment), and from there to a drinking-water buffer that supplies the washbasin, bathtub and shower. Grey wastewater goes to a second buffer, then to a second EOP unit and to a buffer for other uses, from which water flows to irrigation during the growing season. Black wastewater undergoes preliminary treatment and is then fed into the grey-wastewater buffer. About 5% of waste from each EOP unit and the residual waste from preliminary treatment go to infiltration, as does any excess from the buffers (shown as dashed lines in the diagram).
