Performance Improvement of Adsorption Desalination Plant: Experimental Investigation

This article deals with the experimental investigation of a four-bed adsorption desalination (AD) plant working at a relatively high evaporation temperature. The effect of heat source temperature and adsorption/desorption cycle time on the system performance in terms of specific daily water production (SDWP) and performance ratio (PR) is experimentally studied. Owing to the higher evaporation temperature, SDWP of the plant is increased by two folds, to about 8.2 m3 of water/ton-adsorbent per day. Further improvement is also achieved by using mass recovery scheme without significant changes to the AD plant.
