Abstract: This thesis presents a hybrid multi-effect desalination (MED) and adsorption (AD) cycle or simply called as MED+AD in short. It has the thermodynamic synergy of both MED and the batch-operated AD cycles. The combined cycle allows the last stage of MED to operate below ambient, typically 5C, attributed to continued vapor uptake by the regenerated adsorbent of AD. The hybridization of two thermally driven processes has synergistically improved the water production by 2-3 folds, enabling for the first time a thermally driven process to be better than RO process, resulting in a specific energy consumption of less than 14.5kWh_pe/m3. Such a bench mark is even lower than what existing RO plants can provide. Both the conventional MED and hybrid MEDAD cycles are simulated, vis-a-vis, with the same operational parameters. The predicted results are then compared to a purposed-built 3-stage MED system, emulating the TBTs of MED from 15 to 70C.
