The CALAGUA group has laboratories at both the University of Valencia (Universitat de València, Burjassot campus) and the Polytechnic University of Valencia (Universitat Politècnica de València, Vera campus).Moreover, in the , as well as the Conca del Carraixet WWTP at Alboraya (Valencia), where it operates a series of pilot plants that deal with treat urban wastewater in real conditions.



In the wastewater field it is crucial to work with an actual inflow in a plant large enough to be able to extrapolate and transfer the results to actual situations. This is why CALAGUA works with pilot plants in a number of WWTPs to be sure of obtaining valid results from tests on proposed technologies.
