MEMBRANE DISTILLATION WITH LAMINAR-FLOW

Direct-contact membrane distillation (MD) process in a plate-and-frame module with laminar flow is investigated. The performance of a MD pro cess is strongly influenced by heat transfer taking place within the m embrane modules. The present study is concerned mainly with heat trans fer across membranes, and specifically with assessing the applicabilit y of existing heat-transfer coefficient correlations to MD membrane mo dules.
