Evaluating Critical Influencing Factors of Desalination by Membrane Distillation Process-Using Multi-Criteria Decision-Making.

摘要: Water desalination by membrane distillation (MD) can be affected a wide range of operating parameters. The present work uses combinational approach Analytical Hierarch process (AHP) and Fuzzy Hierarchy (Fuzzy-AHP) to identify the most important parameters in MD desalination. Five key-performance indicators, named derivable outputs (DOs), are considered, along with critical factors affecting these DOs current study. influencing (CIFs) selected based on their experimental feasibility. investigation involves five DOs, which liquid entry pressure, thermal power consumption, permeate quality, flux, pumping (feed circulation) power. A total twenty-five factor were associated DOs. identification CIFs was literature review, further analyses performed. Both methods, AHP Fuzzy-AHP, determined six extremely MD, feed temperature, concentration, or salinity; flow rate; hydrophobicity; pore size; material. Moderately found four both methods. These common solution properties, thickness, channel geometry, pressure difference channel. Finally, least preferred methods that configuration, duration test, specific heat solution, viscosity.
