Boiler water treatment chemicals - oxygen scavengers, alkalinity boosters, scale inhibitors - all need to be dosed to reach a specific target concentration, not just added in arbitrary amounts.
Formula: Dosage (g) = concentration (mg/L) × volume (L) ÷ 1000
Example: reaching a 50 mg/L target concentration in 10,000 L of boiler water requires 500 g of chemical.
How to Use This Calculator
- Enter the target concentration in mg/L.
- Enter the total water volume being treated.
Under-dosing risks corrosion or scale formation; over-dosing wastes chemical and can itself create water chemistry problems - both reasons accurate dosing matters more than "adding a bit extra to be safe."
