Plan dosing with flexible units and easy outputs. Review dosage, stock strength, runtime, and cost. Use examples, formulas, exports, and graphs for confident calculations.
The page stays single-column, while inputs use 3 columns on large screens, 2 on smaller screens, and 1 on mobile.
| Scenario | Volume | Current | Target | Product Strength | Density | Estimated Product Needed |
|---|---|---|---|---|---|---|
| Cooling Water Chlorination | 5000 L | 0 mg/L | 2 mg/L | 12.5% | 1.20 g/mL | 66.67 mL |
| Sanitizer Boost | 10000 L | 1 mg/L | 4 mg/L | 10% | 1.10 g/mL | 272.73 mL |
| Laboratory Stock Adjustment | 2500 L | 0.5 mg/L | 1.5 mg/L | 35% | 1.18 g/mL | 6.05 mL |
1) Convert the treatment volume to liters
Volume (L) = input volume × unit conversion factor
2) Convert concentration to mg/L
Target increase (mg/L) = Target concentration − Current concentration
3) Compute active ingredient needed
Base active dose (mg) = Target increase (mg/L) × Volume (L)
4) Apply loss and safety adjustments
Adjusted active dose = Base dose × (1 + loss%) × (1 + safety%)
5) Convert product strength into available active per mL
Active mg/mL = Density × 1000 × Strength fraction × Purity fraction
6) Find commercial product needed
Product volume (mL) = Adjusted active dose ÷ Active mg/mL
7) Estimate diluted feed solution and runtime
Diluted feed (L) = Product volume (L) × Dilution ratio
Runtime (hours) = Diluted feed (L) ÷ Pump flow (L/hour)
For dilute water systems, ppm is treated approximately equal to mg/L. Always verify plant standards, chemical compatibility, and safety rules before dosing.
It estimates active ingredient demand, commercial product volume, diluted feed volume, pump runtime, and cost. It is useful for treatment, cleaning, lab, and process dosing work.
For dilute aqueous solutions, ppm is commonly treated as equal to mg/L. In dense, non-aqueous, or highly concentrated systems, use the proper conversion for your process.
Strength represents labeled active content, while purity reflects the actual assay or usable fraction. Keeping both fields separate lets you model commercial products more accurately.
Process loss covers chemical decay, line losses, incomplete transfer, side reactions, and other field inefficiencies. Adding it helps avoid underdosing when real conditions are less than ideal.
The dilution ratio does not change the active dose. It only changes the final feed solution volume, added water, and pump runtime for the delivery system.
If the current concentration already matches or exceeds the target, more chemical should not be added. The calculator sets the added dose to zero and shows a note.
Yes. Enter the batch count to scale treated volume, product demand, diluted feed, runtime, and total cost across repeated identical batches.
No. It is a planning and estimation tool. Always confirm dosage with jar tests, operating procedures, chemical supplier guidance, and site safety requirements.
