1. What is Active Polymer Dosage?

Definition: Active Polymer Dosage refers to the amount of active polymer required per unit volume of wastewater for effective treatment.

Purpose: It helps water treatment professionals determine the optimal amount of polymer needed for coagulation, flocculation, or other treatment processes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Pd \) — Active Polymer Dosage (kg/m³)
• \( P \) — Active Polymer quantity (m³/s)
• \( W \) — Waste Water Flow rate (m³/s)

Explanation: The active polymer quantity is divided by the wastewater flow rate to determine the dosage required per unit volume.

3. Importance of Active Polymer Dosage Calculation

Details: Proper dosage calculation ensures effective wastewater treatment while minimizing chemical costs and potential environmental impacts.

4. Using the Calculator

Tips: Enter the active polymer quantity in m³/s and wastewater flow rate in m³/s. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is active polymer in wastewater treatment?
A: Active polymers are chemicals that can change properties in response to stimuli, used for improving solid-liquid separation in treatment processes.

Q2: How do I measure active polymer quantity?
A: Polymer quantity is typically measured by the feed rate of polymer solution to the treatment system.

Q3: What factors affect polymer dosage requirements?
A: Wastewater characteristics, polymer type, treatment objectives, and system design all influence dosage requirements.

Q4: What are typical dosage ranges?
A: Typical dosages range from 0.1 to 10 mg/L (0.0001 to 0.01 kg/m³), but vary based on specific applications.

Q5: How often should dosage be recalculated?
A: Dosage should be reviewed whenever wastewater characteristics change or treatment performance declines.
