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 preparation unit principle

Depending on the customer’s choice, the polymer preparation can either be manual, batch produced or fully automatic.

Liquid concentrated polymers are diluted in 2 chamber systems, featuring a mixing compartment and a storage compartment. Clear water is fed to the system and, depending on the requested final concentration, a known amount of liquid polymer is injected. The mixer in the first compartment dissolves the polymer into the water. When ready, this solution flows to the second compartment – used as storage – from which it can be pumped into the process.

Powder polymers are diluted in 3 chamber units. The first compartment is used for active mixing of the powder into the water flow. In the second chamber, the solution is matured by additional mixing. The third chamber acts as storage chamber. Powder polymer units are fitted with a powder storage hopper and dosing screw. The unit doses know amounts of powder into the incoming clean water flow, controlled by the water panel.

Manual and batch units require operator interactions, where fully automatic units start the solution preparation cycle automatically whenever the start level is reached in the storage chamber. The automatic unit can be used for continuously polymer injection into treatment processes.

Polymer preparation unit advantage

Lower Maintenance & Downtime: No moving parts in the mixing process along with the durable DFXa peristaltic or gamma/ XL diaphragm pump means fewer breakdowns and less frequent repairs.

More Efficient Polymer Usage: Venturi mixing & static mixer ensure optimal polymer activation, reducing chemical waste. Consistent dosing improves treatment efficiency, lowering operating costs.

Ease of Operation & Automation: Multiple control modes (Manual, Analog, Contact, Auxiliary) allow simple or advanced operation. 4-20 mA and alarm outputs enable remote monitoring and integration with SCADA/PLC systems.

Compact & Easy Installation: Lightweight and space-saving design allows easy integration into existing site locations without major modifications. Simple piping and electrical connections make setup fast and easy.

Reliable Performance: Handles various polymer types (emulsion, solution, low molecular weight). Works across a range of flow rates (60–600 GPH) and pressures (up to 100 PSIG).

Reduced Energy Consumption: Low-energy mixing minimizes power usage, leading to cost savings.

Safe & Operator-Friendly: No high-speed mechanical parts, reducing risk of injury. Designed for low-maintenance operation, allowing operators to focus on other tasks.
