Ion Exchange & CEDI System Designer
A vendor-neutral resin vessel sizing and regeneration calculator for softening, cation, and anion demineralization duty, paired with a Faraday's-Law-based DC current and budgetary power estimator for a downstream continuous electrodeionization (CEDI) polishing train — built for industrial ultrapure water and high-pressure boiler feedwater makeup systems.

Ion Exchange Resin & CEDI System Designer
Resin vessel sizing and regeneration chemical consumption for softening/demineralization duty, plus Faraday's-Law-based DC current and budgetary power estimation for a downstream CEDI polishing train.
Enter as mg/L expressed as CaCO3 (standard "as CaCO3" convention).
Standard commercial softener brine is typically 8-10%.
Typical CEDI module range: 250-600 V DC. Real stack resistance is proprietary module-design IP — see methodology note below.
Export includes both modules' current configuration and results, regardless of which tab is active.
Engineering 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.

Most ZLD comparisons pit MVR against MEE against membrane distillation as if picking one settles the design. The bigger lever is upstream: every extra point of recovery a membrane train squeezes out before handoff removes disproportionate capital and energy from whatever thermal step comes after it.
