PAM polymer preparation unit Description

Polymer Preparation System is a compact automated metering unit for liquid or powder polymer preparation and dosing. Designed specifically for uniformity of flocculant concentration, the design is optimized to ensure that the polymer completes the maturation process with minimal footprint. Also often referred to as powder dosing systems, Polymer Dosing Systems, PAM PAC dosing systems.

The pre-assembled polymer unit features two cylindrical chambers for dosing, maturation and storage of liquid or powdered polymer solutions, which are hydraulically coupled via overflow channels. In addition, three motorized stirrers provide agitation to ensure consistent performance.

Polymer dosing device
Polymer dosing device is composed of hopper, push screw, electric heater and etc. The effective volume of the hopper can meet the dosage for a long time which is equipped with sight glasses for observing material level monitored by the dry powder level meter. The push screw driven by the high-precision reducer can satisfy the dosage. The electric heater can be installed in the discharge pipe of push screw, and it can prevent the powder from caking.

Polymer dissolving device
Polymer dissolving device is composed of pre-soaking device, tank, and 3 sets of mixers. The pre-soaking device is to infiltrate and mix the polymer powder in advance. The 3 tanks are precast mixing tank, homogeneous slaking tank and solution storage tank, in which there is a mixer correspond to guarantee the homogeneity.

Water supply device
Water supply device is composed of pipeline, manual ball valve, filter, pressure gauge, solenoid valve, stop valve, and the rotor flow meter, etc.

PAM Polymer Preparation Unit Model

PAM Polymer Preparation Feature

• Fully automated operation — saves labor costs and prevents dosing errors, operation stops
• Standardization of the resulting polymer — concentration, maturation time, homogeneity
• High efficiency mixer — Provides low flow mixing for homogeneous flocculant polymerization without mechanical degradation
• Optimized process — visual access to process and alarms, can feed the process when needed, regulated by ultrasonic level switches
• Compact design — easy to transport and relocate
• Safe and reliable — operation with airlift and overflow protection

PAM Polymer Preparation Application

• Water treatment: flocculation of industrial and drinking water
• Wastewater treatment: physicochemical treatment
• Sludge treatment: centrifuges, screw presses, filter presses to improve dewatering
• Mining: concentrate sludge will sink to the bottom faster Speeds up production
• Paper industry: retention aid
• Cooling water treatment: inhibitors and biocides
