Calculation of the required oxidant dosage according to water chemistry

Calculation of the required oxidizer dosage according to the water chemistry for iron and manganese catalytic equipment.

We offer assistance in calculating the dosage of an oxidant: oxygen, ozone and chlorine required for a given water chemistry. It is for use in equipment that uses iron or manganese catalysts and requires the presence of free chlorine to maintain its performance at an optimum level. The dose of oxidizer needed for a specific water chemistry depends on the composition of the water.

Water quality ratios

The ratio of oxidant to water is determined by the water chemistry. The following table shows the ratios of oxidant to water as a function of pH and temperature.

Calculated equation for the oxidant dose

To calculate the oxidizer dosage, you must use the following equation. This is a function of water chemistry and will provide a value for your oxidizer dose as a function of water chemistry. The oxidizer dosage depends on the pH of your wastewater (if applicable) and can be calculated by multiplying this value by 1.5, a quantity that takes into account heat losses during the reaction in tanks with lower temperatures or when flow rates are high compared to the design capacities of the equipment. The following table provides typical values for various ranges of operating conditions:

Calculated tables for oxidant dosage

The following tables show the calculated oxidant doses for each type of oxidant, based on water quality ratio (WQR), water chemistry and oxidant type. The data were obtained using a computer model that simulates the chemical reactions involving iron and manganese. The results were then compared with measurements made in industrial plants with similar processes to verify their accuracy.

Conclusion: Oxygen, ozone and chlorine are used to catalytically remove iron and manganese from water.

In conclusion, the dose of oxidant needed depends on the water chemistry. Oxygen, ozone and chlorine are used to catalytically remove iron and manganese from water. The correct oxidant dosage is an important consideration in iron and manganese removal. Based on the water chemistry, a value can be calculated for each type of oxidizer. This will help you determine which one is best suited for your application.
