Engineering Basis
Methodology
Resin volume is sized from total ionic throughput (flow x run time x influent concentration) divided by operating capacity, with regeneration dose vs. capacity following a published reference curve for standard gel-type strong-acid-cation softening resin; demineralization service types use static handbook capacity/dose defaults given thinner public curve data for H+/OH- regeneration.
DC current is derived rigorously from Faraday's Law against the feed's ionic load (Feed Conductivity Equivalent, correcting for CO2 and silica) and an adjustable current-efficiency assumption; voltage is a user-editable planning assumption within the published 250-600 V DC module range, since real stack resistance depends on proprietary resin-fill/membrane construction — power and specific energy are budgetary estimates only.
Assumptions
Preliminary resin sizing uses generic capacity and vessel assumptions.
CEDI current is a Faraday-based aggregate ionic-load proxy with editable voltage and current-efficiency planning assumptions.
Scope / Limitations
Verify resin, hydraulics, regeneration, and manufacturer data before design release.
Module count, rectifier selection, stack topology, proprietary capacity, and final vendor design are outside the model.
