Proper Sizing
Determine preliminary chlorine chemical requirements, contact tank dimensions, and NaOCl storage capacity.
Engineering Excel Workbook
Size a sodium hypochlorite dosing system, rectangular chlorine contact tank, and NaOCl storage tank within one structured engineering calculation. Review chemical demand, effective contact time, and project-specific design requirements.

Determine preliminary chlorine chemical requirements, contact tank dimensions, and NaOCl storage capacity.
Review chlorine species, chemical consumption, hydraulic retention time, estimated effective contact time, and CT.
Organize chemical, hydraulic, and storage calculations for project-specific engineering review.
A linked calculation sequence, from design inputs to disinfection-system review.
Workbook Experience
Review actual calculation inputs and the linked Dashboard before purchasing the workbook.


Actual chlorine disinfection dashboard excerpt. Example figures are workbook inputs and outputs, not verified project guarantees.
Review sizing outputs against the adopted design inputs and project requirements.
| Review Item | Workbook Evaluation |
|---|---|
| Chlorine design basis | pH, temperature, ammonia, available chlorine and required residual |
| Chemical demand | NaOCl consumption, injection rate, and chemical-strength inputs |
| Contact tank | Dimensions, hydraulic retention, and estimated T₁₀ |
| Disinfection review | Estimated CT; a project CT criterion must be established for acceptance |
| Chemical storage | Tank geometry, usable inventory, and available stock duration |
Example outputs are preliminary. Final dose, CT compliance, equipment selection, and NaOCl storage safety require project-specific engineering and vendor review.
