WP1: 4SM DIGITAL PLATFORM DEVELOPMENT: WP1 aims to create an IoT digital platform to collect and visualize data generated in the experimental WP’s of the project. The platform will be able to carry out data mining and quality checks to ensure only relevant and meaningful data is considered and exchanged. It will also include an Application Programming Interface (API) for the extension and exploitation of the platform.

WP2: ENHANCED H2S STRIPPING UNITS FOR SULFUR RECOVERY: The main goal of WP2 is to design the stripping process unit and to determine the potential to remove sulfide and to recover added-value products from it.

WP3: CHEMICAL-FREE SULFIDE CONTROL IN SEWER: The aim of WP3 is to test a chemical-free ground-breaking method for sulfide control based on electrocatalytic systems and low-cost nanomaterials. Laboratory tests demonstrating the potential of these systems were performed in the framework of the ERC project Electron4water at ICRA. Within 4SM-WP3 we will confirm the obtained results by performing long term experiments at the upscaled sewer systems under environmentally realistic conditions

WP4: AUTONOMOUS DRONES FOR AUTOMATIC DATA RETRIEVAL AND INSPECTION: WP4 focuses on the conceptualization, implementation, and test of an aerial autonomous vehicle (drone) solution for automatic data gathering and device health monitoring for sensors installed on sewer networks

WP5: SMARTER SENSORS FOR WASTEWATER QUALITY CONTROL:The purpose of WP5 is to test wastewater quality sensors measuring pH, temperature, turbidity, chemical oxygen demand and ammonia to integrate them in the CSO detection device for the real-time monitoring of the CSO and spills in sewer systems. We will expose the sensors to the tough conditions encountered in sewers and improve their capabilities for reliable sewage quality parameters

WP6: ENERGY HARVEST FROM SEWERS: The aims of WP6 is to design a sewer-adapted pico-turbine to generate energy from flowing wastewater, and to develop a software application able to determine potentially suitable spots-cities to implement the pico-turbines

ICRA has a unique sewer-mimicking experimental installation that consists of a specially designed laboratory and pilot plant system that reproduces the main characteristics of sewers within its experimental halls. The pilot plant is basically a direct connection-extension of the sewer network of Girona that finishes inside the laboratories of ICRA. The greatest advantage is that permits to work with real sewage but under completely controlled operation conditions such as feed pump frequencies, hydraulic retention times, temperatures, contrary to field-scale sewers, where natural variability tends to difficult in-depth investigations.

EURECAT’s facilities located in Cerdanyola del Vallès include a Robotics and Industrial Automation Laboratory of 500m2, specifically equipped for the design, development, manufacture, and installation of robotic/mechatronic equipment; and an advanced manufacturing laboratory (300 m2) equipped for designing and manufacturing all kind of tools and mechanical elements. This includes 4 realistic robotic industrial cells with several industrial and collaborative robots, and Artificial Vision Laboratory, a lab to develop collaborative applications and a 100m2 ground/aerial robot test arena equipped with a Motion tracking system (Optitrack).

FACSA makes its laboratories, support equipment, hardware, and software (commercial licenses) available to the project to accomplish both the experimental and modelling tasks, mainly in WP2, WP3, and WP6. FACSA has several laboratories where it evaluates the quality of the water. For this project, it will be used to conduct laboratory experiments mainly through physical-chemical water. analysis and H2S measurements. The materials and equipment used are diverse: jar-test bench, respirometers, digesters, flasks, microscopes, fluorimeters, etc. It is this equipment and facilities that FACSA will have available to carry out the project. With regards to modelling equipment for CFD simulations FACSA has licenses for CAD: SpaceClaim v19.2 and CFD: Ansys v19.2 and advanced computational installations including a CAD Workstation for CAD design, a high-performance computing cluster for scientific calculations
