1. What is Dosage Used given Capacity of Chlorinator at Peak Flow?

Definition: This calculator determines the dosage required to achieve coliform reduction based on chlorine requirements, peaking factor, and average flow rate.

Purpose: It helps water treatment professionals calculate the appropriate disinfectant dosage needed for effective pathogen reduction in water systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ D = \frac{Cl_2}{f \times Q_a \times 8.34} \]

Where:

Explanation: The formula calculates the disinfectant dosage needed by considering the chlorine demand, system flow characteristics, and standard conversion factors.

3. Importance of Dosage Calculation

Details: Proper dosage calculation ensures effective disinfection while avoiding over-chlorination which can lead to harmful byproducts and unnecessary costs.

4. Using the Calculator

Tips: Enter the chlorine requirement in kg/s, peaking factor (default 0.9999), and average flow rate in m³/s (default 2.5). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the peaking factor?
A: The peaking factor is the ratio of maximum flow to average daily flow in a water system, accounting for usage variations.

Q2: Why is 8.34 used in the formula?
A: 8.34 is the conversion factor that translates between pounds per gallon and kilograms per cubic meter.

Q3: How do I determine chlorine requirements?
A: Chlorine requirements are typically based on water quality tests, regulatory standards, and system characteristics.

Q4: What's a typical dosage range?
A: Typical chlorine dosages range from 1-5 mg/L (0.001-0.005 kg/m³) for drinking water, but vary based on conditions.

Q5: Does this account for chlorine decay?
A: No, this calculates initial dosage. Additional chlorine may be needed to maintain residual throughout the system.
