Feed Water
From a water analysis anion-sum (as CaCO3) — drives the chemical-equivalent FCE below alongside CO2 and silica.
Electrical & Process Assumptions
Planning assumption only; real stack resistance is manufacturer-specific. Module count, module envelope, rectifier, and topology are not modeled.

CEDI Electrical Proxy — Not Module Selection
PRELIMINARY PROXY ONLY — Faraday current represents aggregate ionic load. Voltage and efficiency are planning assumptions; module count, rectifier selection, stack topology, and manufacturer capacity remain outside this tool.

直流電流は、原水のイオン負荷(CO2およびシリカを補正した原水等価導電率 FCE)と調整可能な電流効率の仮定に基づき、ファラデーの法則から厳密に導出します。電圧はユーザーが調整可能な計画上の仮定値であり、公開されている250〜600 V DCの標準モジュール範囲内で設定します。実際のスタック抵抗はメーカー固有の樹脂充填・膜構造に依存するため、消費電力と原単位エネルギーはあくまで予算レベルの推定値です。
