The purpose of the present research is to carry out an experimental and theoretical investigation for salt water desalination using tubular direct contact membrane distillation. The effect of operating parameters on the unit performance was studied. These parameters include feed water inlet temperature, feed water flow rate, salt concentration and cooling water temperature. System thermal efficiency and gain output ratio (GOR) are also evaluated. The investigated range was, 70oC for inlet feed water temperature, from 15 to 20 L/min for feed water flow rate, from 0 to 40 g Nacl/L water for feed water salt concentration, from 20 to 56 °C for the inlet cooling water temperature, and from 15 to 20 L/min for cooling water flow rate. Maximum productivity, daily efficiency, and Gain output ratio (GOR) of the system reach 40.587 kg/day, 64.88%, and 0.624 respectively. Finally, a good agreement has been found between the present numerical results and experimental results |
