Polymer Feed Rate of Dry Polymer Calculator

Polymer Feed Rate Formula:

\[ P = \frac{D_p \times S}{2000} \]

Polymer Feed Rate (lbs/sec):

Definition: This calculator determines the polymer feed rate needed based on polymer dosage and dry sludge feed rate.

Purpose: It helps water treatment professionals optimize polymer usage in sludge treatment processes.

The calculator uses the formula:

\[ P = \frac{D_p \times S}{2000} \]

Where:

Explanation: The polymer dosage is multiplied by the dry sludge feed rate and divided by 2000 to convert to pounds per second.

Details: Accurate polymer feed rate ensures optimal sludge conditioning, cost-effective polymer usage, and efficient dewatering processes.

Tips: Enter the polymer dosage in lbs/ton and dry sludge feed rate in lbs/day. All values must be > 0.

Q1: What is a typical polymer dosage range?
A: Typical dosages range from 2-10 lbs/ton of dry solids, depending on sludge characteristics.

Q2: How do I measure dry sludge feed rate?
A: Measure total sludge solids and flow rate, then calculate mass flow rate (lbs/day).

Q3: Why divide by 2000 in the formula?
A: This converts from lbs/day to lbs/sec (2000 = 24 hours × 60 minutes × 60 seconds / 43.2).

Q4: What factors affect polymer dosage?
A: Sludge type, solids concentration, pH, temperature, and desired cake dryness.

Q5: Should I include safety factors?
A: Yes, consider adding 10-20% to the calculated feed rate for operational flexibility.
