“…Naveed et al [13] used three and five decision-makers in AHP and Fuzzy-AHP and found having three decision-makers gave more accurate results whereas five decision-makers showed vagueness. Based on the literature review [13,17,18,170,171], three LDMs with more than five years' experience in membrane distillation were considered. One of the decision-makers is from the industrial field (desalination plant), and two are from the academic field.…”

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

“…The inspection concluded that the highest technical and non-technical criteria were salt rejection and cost, respectively. Talaeipour et al [18] applied AHP to find the optimum desalination method for groundwater by comparing nano-filtration (NF), RO and hybrid NF/RO. The study found that the best performance was the hybrid NF/RO.…”
