The motivation of this research arises from the fact that Magnetic nano-particles (MNP) are under development by Masdar
Institute of Science and Technology (MIST)-Massachusetts Institute of Technology (MIT) project for novel salty water
treatment process. MNP will absorb the water from the salty water via Forward Osmosis (FO) concept and the recovery of the
water from the MNP, only requires low temperature thermal energy. This project presents the use of Photovoltaic (PV) cooling
that leads, on one hand, to an increase of PV efficiency and electrical energy productivity, whereas the recovered cooling thermal
energy, on the other hand, will be used for MNP water recovery. The MNP recovery/pure water production process studied
is Humidification Dehumidification (HDH) process. A numerical model has been developed using a MATLAB program to
study the system?s performance under the climatic conditions of Abu Dhabi, United Arab Emirates. The results include the
system?s temperatures, water productivity and system?s effectiveness. For Abu Dhabi climatic conditions, the results show that
the PV cooling produces about 4 liters of pure water per meter squared of PV panel per day, with PV overall (electrical/thermal)
effectiveness of close to 78% at peak sun-hours in the summer.
