Chlorine Dioxide Dosing Formula:
| From: | To: |
Chlorine dioxide dosing calculation determines the required dosing rate for water treatment applications. It accounts for both the demand (amount consumed by reactions) and the desired residual concentration in the treated water.
The calculator uses the dosing formula:
Where:
Explanation: The formula calculates the total amount of chlorine dioxide needed per minute to meet both the reaction demand and maintain the desired residual concentration in the water flow.
Details: Accurate dosing is crucial for effective water disinfection while avoiding under-dosing (ineffective treatment) or over-dosing (waste of chemicals and potential health concerns).
Tips: Enter demand and residual values in mg/L, flow rate in L/min. All values must be valid (non-negative, flow > 0). The calculator will provide the required dosing rate in mg/min.
Q1: What is chlorine dioxide demand?
A: The amount of chlorine dioxide consumed by reactions with organic matter, inorganic compounds, and microorganisms in the water.
Q2: What is a typical residual concentration?
A: Typical residual concentrations range from 0.1-0.5 mg/L for drinking water treatment, depending on regulatory requirements.
Q3: How is flow rate determined?
A: Flow rate is measured using flow meters in the water treatment system and represents the volume of water being treated per minute.
Q4: Are there safety considerations?
A: Yes, chlorine dioxide is a powerful oxidizer and should be handled with proper safety equipment and procedures. Always follow manufacturer guidelines and regulatory requirements.
Q5: Can this calculator be used for other disinfectants?
A: While the basic principle is similar, different disinfectants may have different demand characteristics and residual requirements. Always use specific calculations for each disinfectant type.
