  • Principles of Filtration
    rate is a measure of the amount of water that flows through a filter at a defined pressure. It is related to the degree of contamination, differential pressure, total porosity, and effective filtration area. Commonly expressed in the membrane industry in units of milliliters/minute (mL/min) at a given...

  • Terms Used When Discussing Filters
    . Pore Size (nominal): The pore size at which a particle of defined size will be retained with an efficiency below 100% (typically 90-98%). Rating methods differ widely between manufacturers. Pore Size Rating: The maximum diameter of a channel through the filter medium. Porosity: The percentage...
