Surface Treatment of Air Gap Membrane Distillation (AGMD) Condensation Plates: Techniques and Influences on Module Performance

摘要: Air Gap Membrane Distillation (AGMD) is one of several technologies that can be used to solve problems fresh water availability. AGMD exhibits advantages, including low conductive heat loss and higher thermal efficiency, due the presence an air gap between membrane condensation wall. A previous study by Bhardwaj found surface properties (materials contact angle) affected total collected in solar distillation process. However, process condition differences might result different phenomena. In contrast, N. Miljkovic showed a hydrophobic has transfer. Moreover, best our knowledge, there no investigates effect overall performance (i.e. flux efficiency). Thus, this study, we treated make it or hydrophilic. The could made hydrophilic immersing boiling plate deionized (DI) water, which caused formation aluminum hydroxide (AlOOH) nanostructures. Afterwards, was coated using hexamethyldisiloxane (HMDSO) through plasma-enhanced chemical vapor deposition (PECVD). indicated do not affect permeate efficiency significantly. general, for plates were lower than those non-treated (pristine). at 1 mm 3 gap, outperformed (pristine) terms flux. Therefore, although wettability significant, still provided little influence.
