Industrial Polymer Mixing Unit - High Viscosity Stirrer System

PAM polymer preparation unit Description

Baffles allow the circulation of the polymer preparation through a series of compartments. This ensures the optimum reaction time in each compartment and, a continuous concentration level, thereby avoiding any preferential route between the preparation compartment and the final dosing solution compartment.

The DAGYEE system is automated by the control panel connected to the ultrasonic level detector located above the dosing solution compartment. As soon as the solution in the dosing compartment reaches “low level”, the detector activates the opening of the water feed electrovalve and the start-up of the dry feeder. The water meter controls the flow continuously. As soon as the “high level” is reached, the process cycle stops, although the mixers (one, two or three according the model) continue to operate.

The DAGYEE unit provides automatic and continuous preparation of the polymer solution using a constant and uniform quality, resulting from:

One two-impeller mixer located in the preparation compartment (single impeller in the maturation compartment),
Optimized maturation cycles.
By fitting with an optional dilution unit, the main solution can then be diluted.

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 Function

For solids separation in water treatment applications where effective coalescence and flocculation are required prior to dosing, this dosing system can be used for batch flocculation aids to prepare ready-to-use polymer solutions and is designed for fully automated dosing of polymer solutions.

The baffles allow the polymer formulation to circulate through a series of compartments. This ensures optimal reaction times and continuous concentration levels in each compartment, thus avoiding any preferential routes between the preparation compartment and the final dosing solution compartment.

Automation is achieved by a control panel connected to an ultrasonic level detector located above the dosing solution compartment. Once the solution in the dosing chamber reaches “low level”, the detector activates the opening of the inlet motorized valve and the activation of the dry feeder. The water meter continuously controls the flow rate. Once a “high level” is reached, the process cycle stops.

PAM Polymer Preparation Application

Using polymers and flocculants considerably facilitates the processes of removing particles and solids suspended in liquid in the fo lowing applications: 

• Treating potable and industrial processing water
• Purifying waste water 
• Treating sludge, in order to improve the performance of centrifuges and filter presses
• Processes for the paper, chemical, petrochemical, mineral processing, canning industries
