摘要：

Membrane distillation was investigated by using a hollow fiber module, and the permeate flux were monitored as the feed temperature, feed flow rate, feed concentration, cooling temperature, and cooling water flow rate were varied. A mathematical model of the permeate flux was developed and validated on the experimental data. Agreement between experimental and predicted values was obtained. The parameters of hollow fiber module were studied. The diameter, length and thickness of hollow fiber membranes have optimal values in order to get biggest permeate flux and /or production rate, and each optimal value is related with other parameters
