방법론

선택한 투입량-요구량 또는 실측 초기 잔류 분기와 명목 체류시간, 입력 배플 계수로 구간별 잔류량과 CT를 선별합니다. 사용자 기준과 일반 감쇠 가정은 자동 규제 CT 인정이나 규제 CT 계산이 아닙니다.

Available calculation branches are dose-minus-demand or directly measured initial residual, and single-basin or serial multi-segment contact. There is no separate free-chlorine/chloramine selector; the same generic user-entered decay model is used for either intended chemistry.

Calculated initial residual = max(dose − user-entered demand, 0), unless directly measured initial residual is selected.

First-order modeled residual uses Cend = Cstart exp(−kT10) in each contact segment.

Theoretical detention = volume / flow. T10 = user-entered baffling factor × theoretical detention.

Multi-segment Residual × T10 sums each segment modeled end residual × segment T10, using an entered measured final outlet residual for the final segment term when supplied, including 0 mg/L.

Integrated first-order exposure sums Cstart(1−exp(−kT10))/k, with the k=0 limit Cstart×T10.

The user-entered CT criterion compares with single-basin Residual × T10 or, in multi-segment mode, segment-summed Residual × T10. This is not regulatory CT credit.

범위 / 제한사항

  • 구간별 잔류농도×T10 합계, 출구 잔류농도×전체 T10, 적분 1차 반응 노출량을 구분합니다. 실측 잔류농도 0도 유효합니다.
  • Residuals, dose, and demand use an entered chlorine-equivalent basis in mg/L as Cl2. The model does not distinguish free chlorine from chloramine, model chemical-specific reactions, or select chemistry-specific decay coefficients.
  • There are no pH, temperature, organism, log-inactivation, or reference CT-table inputs. This tool does not calculate required CT or regulatory/pathogen credit; the user-entered CT criterion is a comparison value only.
  • No jurisdiction-specific compliance conclusion, automatic pathogen credit, DBP prediction, or chemical recommendation.
  • Regulatory CT profiling uses measured residual and peak-hour flow for each disinfection segment. This screen uses a user-entered design flow in m³/d, baffling-factor estimates, model-derived intermediate residuals, and at most one measured final residual; its Residual × T10 outputs are not regulatory CTcalc.
  • Baffling factor and decay constant are project inputs. Integrated first-order exposure is not automatically equivalent to a regulatory CT-credit method.
