Dosage Calculator

Calculate the chemical feed rate for your RO/NF system based on flow rate and desired dosage.

Input Parameters

Default: 1.10 (typical for antiscalants)

Dilution is automatically calculated to maintain ~50% pump operation for optimal performance.

Enter Inputs to Calculate

Fill in the feed flow, dosage, specific gravity, and pump capacity to calculate.

Understanding the Calculation

Pump Max (GPM):
Chem Pump GPD ÷ 1440

Pump %:
(100 × Dosage × 0.000001 × Feed Flow × Dilution Factor) ÷ Pump Max

oz per gallon:
128 ÷ Dilution Factor

Auto Dilution Factor:
(0.5 × Pump Max) ÷ (Dosage × 0.000001 × Feed Flow)

Recommended Pump Range: 30% – 70% for optimal accuracy and reliability

Unit Reference: 128 oz = 1 gallon · 1440 min = 1 day

Note: Calculator logic aligned with product dilution worksheet calculations. Actual dosage requirements may vary based on water chemistry and operating conditions. Consult with AXEON technical support for specific recommendations.
