The GW4 WSA is running a weekly webinar series for the academic year 2020-2021.
The series features a guest speaker each week and is aimed at stimulating discussion and knowledge exchange between academics, researchers, water professionals and students.
The series runs every Friday, from 14:30-15:30, and is held on Zoom.

Solar Driven Tri-hybrid Water Treatment System for Future Water Supplies
22/10/21 14.30-15.30 BST
Energy-water-environment nexus is very important to attain COP21 goal, maintaining environment temperature increase below 2oC, but unfortunately two third share of CO2 emission has already been used and the remaining will be exhausted by 2050. A number of technological developments in power and desalination sectors improved their efficiencies to save energy and carbon emission but still they are operating far from their thermodynamic limits. The theoretical thermodynamics limit for seawater desalination at normal conditions is about 0.78 kWh per m3 depending on the initial salt contents. However, practical plants are operated at several folds higher than this limit due mainly to inherent losses in the processes which are incurred in removing dissolved salts. Technological advancement in thermally driven processes hybridization has set the new benchmark for lowest energy consumption that has boosted the water production trend of the desalination industry. In this paper, we presented multi-effect desalination (MED) hybridization with Adsorption (AD) cycle to overcome lower brine temperature limitations of MED and their integration with membrane distillation (VMD) to exploit the energy of rejected brine from the MED system. The overall system is operating 100% with solar energy. The excellent thermodynamic synergy of tri-hybrid MED+AD+MD permits an effective utilization of heat input from sun, leading to a boost in water production up to 3 fold. We showed that the proposed tri-hybrid cycle can achieve the highest performance SUPR>25% of thermodynamic limit: one of the highest reported in the literature up till now. These figures can be translated to less than US$ 0.40/m3: – a lowest specific cost ever reported in the literature. The proposed tri-hybrid cycle is successfully tested at pilot scale at KAUST, Saudi Arabia with solar energy.
