The ‘WaterReuse’ project, developed in full form in the region of Murcia, has allowed us to design and build a prototype able to clean wastewater from the chemical and food sectors. This initiative, registered in the European program Life and that had a budget of 1,680,000 euros, has been developed by the chemical company Destilerías Muñoz Gálvez in collaboration with the National Technological Centre for the Preserve, integrated in the network of Technology Centres of the Region of Murcia and which the Institute of Development maintains a collaboration agreement. The objective of this project, which ended last September 30 after a period of two years of work, has been the reuse of industrial wastewater after treatment that eliminates contamination, does not generate sludge and minimizes the carbon footprint thanks to use of membrane technology, electrochemistry and photocatalysis. Thus, the prototype developed under the project ‘WaterReuse’ has the environmental advantage of not requiring the use of additives or chemical reagents or add new pollutants in the treatment process without producing other waste. The operation is automated by a system control and data acquisition system that allows information at all times about the process variables and to intervene on them. In addition, the prototype generates hydrogen as a byproduct, which can be used both as environmentally sustainable energy vector as a chemical reagent. The carbon footprint of this treatement is zero, thanks to the use of renewable energy from solar panels connected to the system and the hiring of electricity supply from renewable sources. The results demonstrate the ability of ‘WaterReuse’ to completely remove both suspended solids and dissolved pollution, allowing the reuse of up to 95 percent of the processed water. The system is particularly effective against difficult to treat effluents with traditional biological methods, such as those in which toxic substances are present, the initial contamination is too high or has high salinity. As a member of the network of technological centres assigned to the Institute for the Promotion of Murcia, the National Technological Center for the Preserve receives, on his part, an important support for the promotion of research, development and innovation projects, as ‘WaterReuse’, an initiative that will be a breakthrough for the Murcian economy thanks to the importance that the chemical and food sectors have in the Region of Murcia.
The ‘WaterReuse’ project has been developed together with the National Technological Centre for the Preserve, with whom the INFO maintains a collaboration agreement.
