AB  - Microelectromechanical systems (MEMS)-based filter with microchannels enables the 
      removal of various microorganisms, including viruses and bacteria, from fluids. 
      Membranes with porous channels can be used as filtration interfaces in MEMS 
      hemofilters or mini-dialyzers. The main problems associated with the filtration 
      process are optimization of membrane geometry and fouling. A nanoporous aluminum 
      oxide membrane was fabricated using an optimized two-step anodization process. 
      Computational strength modeling and analysis of the membrane with specified 
      parameters were performed using the ANSYS structural module. A fuzzy simulation 
      was performed for the numerical analysis of flux through the membrane. The 
      membrane was then incorporated with the prototype for successive filtration. The 
      fluid flux and permeation analysis of the filtration process have been studied. 
      Scanning electron microscope (SEM) micrographs of membranes have been obtained 
      before and after the filtration cycles. The SEM results indicate membrane fouling 
      after multiple cycles, and thus the flux is affected. This type of fabricated 
      membrane and setup are suitable for the separation and purification of various 
      fluids. However, after several filtration cycles, the membrane was degraded. It 
      requires a prolonged chemical cleaning. High-density water has been used for 
      filtration purposes, so this MEMS-based filter can also be used as a 
      mini-dialyzer and hemofilter in various applications for filtration. Such a 
      demonstration also opens up a new strategy for maximizing filtration efficiency 
      and reducing energy costs for the filtration process by using a layered membrane 
      setup.
