Characteristics, Chemical Ratios, and Dosing Methods of Activated Carbon Powder Dosing Systems

Dosing devices can quantitatively feed water treatment chemicals according to set requirements, significantly reducing various costs and avoiding errors in intermediate steps. In recent years, they have been widely adopted. Below, we will explore the characteristics of the activated carbon powder dosing system as well as the mixing ratios and dosing methods for various chemicals.

I. Characteristics of Activated Carbon Powder Dosing System

1. Utilizes a high-precision feeder to ensure accurate dosing.

2. Efficient bridge-breaking mechanism effectively prevents powder bridging.

3. Equipped with pipeline flushing and dilution devices to effectively prevent clogging.

4. Unique conveying system design with monitoring of enclosed delivery pipelines.

5. Fully automatic operation reduces labor costs, utilizing PLC for remote control.

II. Mixing Ratios and Dosing Methods for Various Chemicals

1. Coagulant

• Chemical Name: Polymeric Aluminum Chloride (PAC)

• Mixing Method: Prepare at 10%-15% concentration by weight (1 part PAC to 9 or 7 parts water). Stir uniformly with a mixer before use.

• Dosage: Determine through water quality testing; generally 20-50 mg/L at the above concentration.

• Dosing Method: Use a dedicated PAC dosing system with metering pumps, or direct dosing into the tank.

2. Flocculant

• Chemical Name: No.3 Flocculant (Polyacrylamide PAM)

• Mixing Method: Prepare at 1%-2% concentration by weight (1 part PAM to 99 or 98 parts water). Stir for 1.5-2 hours for maturation before use.

• Dosage: Determine through water quality testing; generally 5-10 mg/L at the above concentration.

• Dosing Method: Use a dedicated PAM dosing system with gas metering, without secondary pollution.
