Polymer Dosage Formula:
From: | To: |
Definition: This calculator determines the polymer dosage required based on the polymer feed rate and dry sludge feed rate.
Purpose: It helps water treatment professionals optimize polymer usage in sludge treatment processes.
The calculator uses the formula:
Where:
Explanation: The formula calculates the polymer dosage by scaling the polymer feed rate relative to the dry sludge feed rate.
Details: Proper polymer dosage ensures effective sludge treatment, optimal polymer usage, and cost efficiency in water treatment processes.
Tips: Enter the polymer feed rate and dry sludge feed rate in kg/s. Both values must be greater than 0.
Q1: Why is the 2000 factor used in the formula?
A: The 2000 factor is a conversion constant that scales the ratio to appropriate units for polymer dosage measurement.
Q2: What's a typical polymer feed rate?
A: Polymer feed rates vary based on sludge characteristics, but typically range from 0.0001 to 0.01 kg/s.
Q3: How do I determine dry sludge feed rate?
A: Dry sludge feed rate is measured from your treatment system's sludge production data.
Q4: What units is the polymer dosage in?
A: The result is a unitless ratio representing the dosage relationship between polymer and sludge.
Q5: Does this calculator work for all polymer types?
A: Yes, but optimal dosage may vary between different polymer formulations.
