RichWater is a modular technology reclaiming water from domestic/urban wastewater for combined irrigation and fertlisation purpose. The system allows to produce high quality effluent meeting the regulatory standards for irrigation of crops to be consumed by humans while preserving the content of nutrients relevant for the fertilization effect. The complete system is composed of four modules: i) wastewater treatment module consisting of a Membrane Bioreactor; ii) mixing unit; iii) fertigation module; and iv) control and monitoring unit.
Technology validated in relevant environment.
Fidelity of breadboard technology increases significantly. The basic technological components are integrated with reasonably realistic supporting elements so they can be tested in a simulated environment. Examples include “high-fidelity” laboratory integration of components.
Testing plan completed
The testing plan and the BRIGAID’s Testing Innovation Framework (TIF) has been rightly applied and finished. The TRL of the innovation has been effectively reached.
The technology has been tested and validated in an operational environment. The test site is a field with a greenhouse and several irrigation sector where several crops have been irrigated with RichWater effluent. Agronomic studies have been performed to proof the validity of the solution. Finally, the final version tested is the one that it is going to be commercialized.

How does it work?

RichWater treatment system is based on a compact Membrane Bioreactor (MBR) for wastewater treatment. The design of the MBR has been adapted to the use of the effluent for irrigation of crops. The design of the RichWater treatment system allows to produce high quality effluent free of pathogens by the use of Ultrafiltration membranes while maintaining optimal content level of nutrients adapting the biological processes. The MBR is assembled to a mixing unit where the MBR effluent is mixed with clear water and a minimum amount of fertilisers according to the crop demands. The mixing unit is assembled to an irrigation system (i.e. fertigation module) which distributes the nutrient rich mixture of reclaimed water and clear water to the crops.
