WATER A.I.D.E.D : modelo de demostración de sistema de recogida y tratamiento de aguas para consumo

This project involves creating a demonstration model of the Greensource solutions. The Greensource solution is a way to harvest, collect and clean rainwater to use it for consumption and irrigation. It uses high tech membrane, activated carbon and UV-C filtration to improve the rainwater to drinking water. The first phase of this project is the design of the demonstration model, including a filter system, monitoring system and control system. By means of the Zeiler method the different functions of the system are determined. For these functions some solutions have been devised and in a morphological overview some combinations of solutions are combined to a proposed concept. These are valued and the best becomes the basis for the final concept. The final concept of the demonstration model consists out of a filtering unit with a membrane filter and UV-C filter. The electrical system includes a Siemens Logo! as a main component, this device monitors and controls the other system elements like the pumps, valves and sensors. The monitoring system contains a Raspberry Pi with digital sensors to measure the different values to display on the main screen. The second phase of this project is the constructing of the designed demonstration model. The proper assembly of the different parts is important in order to guarantee a good functioning of the product. In this phase an adjusted piping and instrumentation diagram (P&ID) was created. To resemble the original Greensource idea, the new P&ID is based on the original one. The power supply had also been ensured, therefore the team has devised an electrical design with fuses, relays etcetera. In preparation for the connection and testing of the electrical components and the PLC, a control program has been created for the Siemens Logo!. Regrettably the team could not implement the control system anymore. With regard to the operating systems, the project team concludes that it would have been better to first start on the electrical design, power supply, then with the control system. Unfortunately, the demonstration model is not completely finished yet. The team got the model working at the smart solution festival through a temporary adjustment. Most of the originally planned parts have now been assembled, but not all of these parts have arrived on time and therefore have not yet been assembled. The current state of the demonstration model is that all cover plates are mounted but that the piping is not yet finished. The electrical system is mounted, but not yet connected. Identical like the monitoring system. The project team concludes that better inventory with regard to the duration of different processes would help with keeping the project on schedule. For example, order processes, development processes and so on. Furthermore, another conclusion is that it is essential to have better and clearer consultations with stakeholders regarding technical support and orders.Escuela Técnica Superior de Ingeniería de TelecomunicaciónUniversidad Politécnica de Cartagen
