ECONOMIC AND ENVIRONMENTAL SUSTAINABILITY

CALAGUA group works on the environmental and economic impact assessment of technologies used for treating wastewater and other wastes. We study and evaluate new alternatives in the wastewater treatment field that allow for economic and environmental impact reduction.  Life cycle analysis is a key tool to assess the sustainability of these technologies, both from an economic point of view (LCC, Life Cycle Costing) and from an environmental point of view (LCA, Life Cycle Assessment). The main objectives when LCC and LCA are

PHOTOBIOREACTORS & MICROALGAE PRODUCTION

CALAGUA group is studying an alternative to the conventional treatment for nutrient removal based on cultivating microalgae in photobioreactors and separating them from the effluent by membranes (membrane photobioreactors or MPBR). Membranes can be used to obtain good quality reusable water.   Microalgae eliminate the nutrients present in the wastewater using Sunlight as energy source and while fixing atmospheric CO2 , which presents beneficial effects on the environment. The generated microalgae biomass can be used to generate

MEMBRANES FOR WASTEWATER TREATMENT

  The CALAGUA Mixed UV-UPV Unitgroup is working on membrane applications with the aim of transforming waste water into a provider of resources such as energy, nutrients and reusable water.   Including membranes in the wastewater treatment schemes allows to recover water resources and to fit with the new Circular Economy-based development model. In As tthis research field CALAGUA considers both the scientific and technology transfer points of view, carrying out the experimental studies are

WWTP CONTROL & OPTIMISATION

The CALAGUA group develops control systems and algorithms for the most important processes in wastewater treatment. The algorithm designs are based on numerical simulations and subsequent validation in pilot plants. Most of the controllers developed to date have also been validated in full scale WWTPs.   The currently available control systems developed by the research team include the following: Aeration controllers for systems using turbocompressors, blowers and/or turbines Control of biological nitrogen removal using low-cost probes

MATHEMATICAL MODELLING

The CALAGUA group is developing mathematical models that are able to reproduce the different types of process included in its research trajectory.   Some of the most important are those for sedimentation and primary sludge fermentation, and those for acid-base, precipitation, 2-stage nitrification, sulfurogenesis and filtration processes. CALAGUA develops calibration parameters for the different numerical models validated by lab, pilot and plant-scale experimental data.   To facilitate the application of the numerical models to WWTP design
