Dry Sludge Feed Formula:
From: | To: |
Definition: This calculator determines the dry sludge feed based on the polymer feed rate and polymer dosage in wastewater treatment processes.
Purpose: It helps wastewater treatment professionals calculate the appropriate sludge feed rate when using dry polymer treatment.
The calculator uses the formula:
Where:
Explanation: The polymer feed rate is multiplied by 2000 (conversion factor) and divided by the polymer dosage to determine the dry sludge feed rate.
Details: Accurate calculation ensures proper sludge treatment, optimal polymer usage, and efficient wastewater treatment plant operation.
Tips: Enter the polymer feed rate in kg/s and the polymer dosage. Both values must be > 0.
Q1: What is the 2000 factor in the formula?
A: This is a conversion factor that accounts for unit conversions between pounds and kilograms in the original formula derivation.
Q2: What's a typical polymer dosage range?
A: Typical polymer dosages range from 5-50, depending on the sludge characteristics and polymer type.
Q3: How do I determine the polymer feed rate?
A: The polymer feed rate is typically determined by the polymer dosing system's settings and flow measurements.
Q4: Can this calculator be used for liquid polymers?
A: No, this formula is specifically for dry polymers. Liquid polymers require different calculations.
Q5: Why is dry sludge feed important in treatment?
A: It helps determine the appropriate sludge processing capacity and ensures proper polymer-to-sludge ratio for effective dewatering.
