Microfiltration is considered to be intermediate between _______ based on pore size

• A. Ultrafiltration and nanofiltration
• B. Nanofiltration and Reverse Osmosis
• C. Ultrafiltration and Multimedia Granular Filtration
• D. Multimedia Granular Filtration and Nanofiltration

Answer: (C)

Pore size is the key factor in where a filtration process sits in the lineup. Multimedia granular filtration uses the largest open structures and removes bigger particles by depth filtration. Ultrafiltration uses membranes with very small pores, blocking much smaller solutes and many microorganisms. Microfiltration falls between these two, with pore sizes larger than ultrafiltration but smaller than multimedia filtration. So it’s described as intermediate between ultrafiltration and multimedia granular filtration.
