Solar Desalination and Water Treatment Platform aims at the development of applied research in the fields of solar-driven water production and water treatment
- Objectives -
The Desalination and Water Treatment Platform aims at the development of applied research in the fields of solar-driven water desalination production and water treatment. It appears as a response to the growth of water needs, which requires developments in research areas to increase the amount of water available, proceeding in parallel with water quality treatment.
- Technologies -
Water Desalination
Water desalination pilot with clean water production of 1 m3 per day
Consists in a closed circuit composed by a reverse osmosis system, capable to operate waters with salinity levels up to 45g/l and 30% brine recovery rate, hybridised with a AGMD membrane distillation system with 10% brine recovery rate. A flow reactor (MF-PFR) as an intermediate process, for the process of selective removal and recovery of magnesium and calcium hydroxide, by chemical precipitation of brines resulting from reverse osmosis process.
Water Treatment
Solar Photoreactors
Water treatment technologies using direct solar irradiation, as solar photoreactors that use solar irradiation in solar photocatalysis processes (e.g. heterogeneous photocatalysis using TiO2 as catalyst or solar photo-Fenton).
The solar tubular photoreactor with high pathlength, tilted to 40º, equipped with a water pump, volumetric flowmeter, temperature sensors (PT100) and a water buffer tank, that operates in batch mode with water recirculation.
