Antiscalant Dilution Calculator

Antiscalant Dilution Calculator should be used to calculate the amount of PWT antiscalant delivered by dosing pump from a dilution tank, direct from the drum or from a bulk storage facility, into the feed water based on the feed flow and the desired PWT antiscalant active dosage concentration. Use PWT ProDose software to calculate antiscalant dosage concentration in the feed stream.  Please follow general guidelines recommended for use of PWT antiscalants.

Select Antiscalant
Day Tank Volume

System Feed Flow
Antiscalant Dosage

Validation errors: Make sure all fields are filled with numeric values

Note: If the Antiscalant is directly fed into the system, without dilution; than enter Day Tank Concentration as 100% and Tank Vol will be equal to tote volume

General Guidelines

  • It is recommended that the antiscalant concentration in dilution tank be above 10%
  • Use RO permeate for Antiscalant dilution
  • Dilution tank should be drained, cleaned and rinsed every 30-60 days
