01 · DESIGN BASIS
Bed hydraulics and breakthrough basis
Bed hydraulics inputs
Standard bed geometry is calculated in this browser and remains available if the breakthrough Worker is unavailable.
BROWSER CALCULATION
Bed hydraulics
Bed volume = area × depth · Carbon mass = bed volume × bulk density · EBCT = bed volume ÷ flow · Superficial velocity = flow ÷ area
WORKER INPUT
Empirical breakthrough observations
Empirical observations
Enter measured or prepared observations. Values are sent only for the active method.
| Observation | Time (BV) | C/C0 (fraction) | Action |
|---|---|---|---|
| 1 | |||
| 2 | |||
| 3 | |||
| 4 | |||
| 5 |
Empirical observations require 0 ≤ C/C0 ≤ 1 and a nondecreasing curve when ordered by time.
Bed hydraulics: browser. Empirical interpolation and Yoon–Nelson fit: Worker authoritative. No browser breakthrough fallback.
02 · BREAKTHROUGH MODEL
Worker breakthrough result
No current breakthrough result
Run the active observation set through the authoritative Worker to produce a breakthrough estimate. Any input edit clears the previous model result.
03 · REPORTING
Exports and verification
Reports include current project metadata, bed hydraulics, the active dataset, structured Worker results, and diagnostics.
Verification suite
Calculation revision 1.0
115 focused checks cover Worker contract, browser bed hydraulics, empirical interpolation, Yoon–Nelson fit, unit conversion, input validation, and no-fallback behavior.

工程依据
方法
根据面积、深度、堆积密度和流量计算床层几何及水力参数；穿透筛选使用有界经验插值或由 Worker 拟合的 Yoon–Nelson 模型。结果不保证全规模床层寿命，也不会自动进行 RSSCT 到全规模的换算。
Bed volume = area × depth. Carbon mass = bed volume × user-entered bulk density. EBCT = bed volume / flow. Superficial velocity = flow / area.
Empirical mode uses bounded piecewise-linear interpolation between adjacent observations only. It does not extrapolate.
Yoon–Nelson mode fits ln(r/(1-r)) = k t - k τ by ordinary least squares and derives target time from the fitted model.
Bed-volume time converts to service time using entered bed volume and flow; hours convert to bed volumes using the same geometry and flow.
范围 / 限制
- 浏览器可计算滤床几何、炭量、EBCT 和表面流速。穿透模型由权威 Worker 计算；经验插值不进行外推。
- Breakthrough fitting and life calculations run in the Worker. If it is unavailable, no authoritative browser fallback runs.
- Yoon–Nelson does not model competitive adsorption, NOM fouling, mass-transfer-zone physics, or guaranteed field performance.
- RSSCT scale-up advanced model: DEFERRED. No automatic RSSCT-to-full-scale conversion is performed.
- Rotation planning basis is deferred; this version does not claim mechanistic lead/lag outlet prediction.
