    Reverse Osmosis Membrane Design Calculator

    Uploaded by

    jobya_4
    This document discusses a calculator for designing reverse osmosis membrane systems for water treatment. It allows calculating the osmotic pressure coefficient using inputs of osmotic pressure, number of ions per molecule, concentration, and temperature based on the van't Hoff equation. It can also calculate contaminant rejection rates based on influent and effluent concentrations.
