The project has been structured in six Working Packages (WP). In the WP1: a methodology is applied to identify the sources of organic micro-pollutant in hospital. In WP2 and WP3 innovative biological processes (strictly anaerobic systems with biophors connected with aerobic membrane bioreactors) and advanced oxidation technologies (photo-Fenton, UV-H2O2 heterogeneous photocatalysis) are developed and optimised in the laboratory. In the WP4, the operation of two pilot devices, for the treatment of hospital wastewater flows burdened with resistant micro-pollutions and for the treatment of the mixture of hospital wastewater, is being tested in real world conditions. In the WP5 the system’s ability to remove multi-resistant bacteria and their ecotoxicity are being assessed. Also, is assessed the possible treated hospital wastewater reuse in the hospital gardens. Finally, in the WP6 is carried out an economic, technical and environmental assessment of the treatment hospital wastewater systems and actions are being developed for the commercialization of them.

WP01: Methodology development for the identification of micro-pollutants sources in hospitals and assessment of their species and concentration
Object: The development and application of a methodology for the individual organic micro-pollutants’ sources identification in a hospital and for the assessment of their species and expected concentration in hospital wastewater. The methodology will be applied at Venizelio General Hospital of Heraklion.

WP04: Development and operation of pilot units for the integrated hospital wastewater management
Object: The construction and the operation at Venizelio General Hospital of Heraklion two pilot units that will offer integrated wastewater management. The first one will apply advanced oxidation technology to treat specific overburdened wastewater flows, the second one will apply innovative biological processes, advanced oxidation technology and disinfection to treat totally the wastewater by producing, simultaneously, biogas and recovered water.
- D4.1. Advanced oxidation pilot unit for pre-treatment of overburdened wastewater flows
- D4.2. Operational report of the pilot unit for pre-treatment of overburdened wastewater flows
- D4.3. Pilot unit for the treatment of mixture wastewater
- D4.4. Operational report of the pilot unit for the treatment of mixture wastewater
- D4.5. Scientific publications and conference announcements
- D4.6. Public informing, in situ visits of specific population groups and institutions representatives at the pilots units
WP05: Ecotoxicity and treated wastewater reuse assessment
Object: The study of possible removal of multi-resistant bacteria and resistance genes, the ecotoxicity study of the treated wastewater effluents and the possibility study of their reuse at hospital gardens. The WP5 will focus on bacterial faecal infection markers, which are mentioned in the legislation, as well as bacteria important for the public health, which are distinguished for their multidrug resistance to antibiotics (eg Klebsiella penumoniae, Staphylococcus aureus).
Deliverables:
- D5.1. Results report on the ability of pilot units to remove multi-resistant bacteria
- D5.2. Results report on the ecotoxicity of the wastewater effluents and the risk assessment of their disposal in the environment
- D5.3. Results report on the possibility of wastewater effluents reuse
- D5.4. Scientific publications and conference announcements
- D5.5. Information of wider audience through the publication of an article in the local press, in the website and social media

WP06: Pilot units evaluation and commercialization
Object: The economic and technical evaluation of the proposed wastewater treatment units and the recording of Greek hospitals capacity and the characteristics in order to accelerate the commercialization process of the technology.
Deliverables:
- D6.1. Economic, technical and environmental assessment report
- D6.2. Preliminary plan for the implementation of full-scale wastewater treatment units at the Venizelio General Hospital of Heraklion
- D6.3. Greek hospitals’ capacity and characteristics report
