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 preparation unit principle

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.

Polymer preparation unit advantage

Avoid the need for manual operations – Prevent dosing errors, operation stops.
Standardization of the obtained polymer – Concentration, maturation time, homogeneity.
High efficiency mixers – Provide a low flow mixing for a homogeneous flocculant polymerisation without mechanical deterioration.
Optimised process – Visual access to the process and alarms, fieldbus distributed control (optional) provides informative and easy to access equipment and status application updates, controlled costs. Intelligent system that feeds the process when needed, regulated by an ultrasonic level switch.
Reliability and Robustness in Any Environment.
