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 carried out on a pilot scale with commercial membrane modules.

The different membrane technologies studied in this area are as follows:

• Aerobic membrane bioreactors (MBR) for wastewater treatment and obtaining recycled water.
• Anaerobic membrane bioreactors (AnMBR) for assessment of organic matter valorisation erial and producing reusable effluents production for different purposes, for example fertirrigation.
• Membrane systems for harvesting and concentrating algal biomass, which can be used to obtain different value value-added products such as methane, fertilisers, lipids, etc.
• Direct filtration systems for urban wastewater to recover organic mattererial for later use in anaerobic digestion systems.
• Filtration systems based on non-porous membranes to recover methane from anaerobic effluents.
• Filtration systems based on semi-permeable membranes to recover ammonia for use in agriculture.
