保留离子交换树脂初步选型与再生化学计算，同时估算 CEDI 总离子负荷/电流；不对模块和整流器进行选型。
Preserve preliminary ion-exchange resin sizing and regeneration chemistry while providing a Faraday-based CEDI ionic-load/current proxy. CEDI module count, rectifier selection, and stack topology are not modeled.
Enter as mg/L expressed as CaCO3 (standard "as CaCO3" convention).
Cylindrical service vessel diameter — used to check bed depth and empty-bed linear velocity below.
Standard commercial softener brine is typically 8-10%.

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

Export includes both panels' current configuration and results; CEDI output is explicitly a proxy, not module or rectifier selection.

树脂装填体积由总离子负荷（流量 x 运行时间 x 进水浓度）除以工作交换容量得出，再生药耗与交换容量的关系基于标准凝胶型强酸性阳离子软化树脂的公开参考曲线；除盐用途（阳床/阴床）由于 H+/OH- 再生的公开曲线数据较少，采用手册典型值作为静态默认值。
直流电流严格依据法拉第定律，基于进水离子负荷（进水等效电导率 FCE，已对 CO2 与二氧化硅进行修正）与可调节的电流效率假设推算；电压为用户可调的规划假设值，取值范围参考已发表的 250-600 V DC 典型模块范围——真实膜堆电阻取决于厂家专有的树脂填充/膜材构造，因此功耗与单位能耗仅为预算级估算。
