Chlorine Dosing Calculator

Estimate chlorine dosing pump rate from water flow, target chlorine dose, and chemical strength.

Calculator Inputs

Chlorine Dosing Calculator guidance

Dosing rate mL/h = flow L/h x target dose mg/L / (chemical strength percent x 10).

Input meaning

  • Water flow: enter the measured, quoted, or hospital-approved value in L/h.
  • Target chlorine dose: enter the measured, quoted, or hospital-approved value in mg/L.
  • Chemical strength: enter the measured, quoted, or hospital-approved value in %.

Result interpretation

  • Use the result as a planning estimate, not as a final approval by itself.
  • Record the assumptions used so Procurement, Biomedical, Facilities, Finance, and vendors can review the same basis.

Assumptions

  • Final dosing must be confirmed with water testing and chemical safety procedures.
  • Dialysis water systems require strict residual chlorine/chloramine monitoring and carbon filtration review.

Biomedical use

  • Use this calculator during RFQ preparation, technical evaluation, acceptance planning, service review, or biomedical workload planning.

How to identify the required values

Use these examples and common working ranges to choose values from gauges, labels, manuals, datasheets, RFQs, service reports, CMMS records, or hospital planning assumptions.

FieldExample valueCommon rangeTip
Water flowExample: 10 L/h.Usually 0.01 L/h or higher; use the real hospital value.Use the actual set flow or expected average flow for the clinical scenario.
Target chlorine doseExample: 2 mg/L.Common starting dose is often 1-3 mg/L, but final dosing depends on water test results.Use the target residual/dose from the water treatment procedure and confirm by testing.
Chemical strengthExample: 5 %.Commercial sodium hypochlorite may be around 5-12%; verify the label.Check the chemical label or safety data sheet.

Common ranges are starting points for hospital planning. For final procurement, acceptance testing, electrical design, medical gas design, radiation shielding, dialysis water systems, or clinical use, replace the example values with site-specific data and vendor-confirmed figures.

Input Checklist

Confirm these values before relying on the output for procurement, PM, or service planning.

  • Water flow
  • Target chlorine dose
  • Chemical strength

Safety And Engineering Notes

Use calculator outputs as planning estimates and verify critical systems with calibrated measurement or qualified engineering review.

  • Final dosing must be confirmed with water testing and chemical safety procedures.
  • Dialysis water systems require strict residual chlorine/chloramine monitoring and carbon filtration review.
