Abstract

Response surface methodology (RSM) has been applied for modeling and ptimization in utilization of vacuum membrane distillation on Lithium Cloride-water absorption refrigeration system (ARS). The effect of the operational parameter is initial feed concentration, feed inlet temperature, feed flow rate and interaction on the permeate flux. The developed model has been statistically validated by analysis of variance (ANOVA) and further used to predict the permeate flux. The result for the given factors is a saddle point one, which meant for the range given, there is no optimal value. This saddle point parameter is outside the data range which is concentration of 24.41 %, feed temperature at 65.03°C and flow rate 0.88 L.min-1 while its predicted flux value is 166.9 g.m-2.s-1.
