Status of membrane distillation for water and wastewater treatment—A review

摘要: AbstractMembrane distillation (MD) is a promising separation technique for water treatment. It nonisothermal process known since 1963. However, this technology still needs to be developed its industrial implementation different purposes. This paper presents status review of MD based on the available published literatures and preliminary analysis. The covers concept, membranes modules design, configurations, performance parameters, fouling phenomena, heat mass transfer applications, energy assessment, integration, Memstill process. Earlier study indicates that permeate quality obtained by stable practically independent feed concentrations. flux strongly affected temperature, flow rate, vacuum pressure in MD, boundary layer coefficient. literature disagree an order enormity hence better ex...
