Abstract

A mathematical model is developed to assess the performance of a hollow-fiber air gap membrane-distillation (AGMD) system for water desalination applications. Validation of results shows outstanding agreement with the experimental results of permeate-flux. Impacts of important variables like feedtemperature, feed-flowrate, and membrane length on permeate flux are systematically examined. Results show that intake feed temperature is the most significant factor in improving permeate-flux. At feed-temperature of 80°C and flow-rate of 1 L/min, the permeate-flux reaches approximately 23.2 kg/m²·hr, while at lower temperatures, such as 40°C, it drops to around 2.3 kg/m²hr. Conversely, increasing membrane length from 0.25 m to 2 m reduces permeate flux values from 14.38 kg/m²hr to 14.16 kg/m²hr at the specific operating conditions of feed-flowrate and inlet feed-temperature due to increased mass transfer resistance and reduced driving force.
