Automatic Flocculant Dosing Skid

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

The polymer preparation system is an intelligent, fully automatic, continuous and integrated dry powder dissolving and dosing device. The device consists of a water supply system, a dry powder dosing system, a dissolving and curing system, and an automatic control system.

This device is a fully automatic continuous configuration and dosing system for powdered medicaments. The dry powder agent enters the premixer from the screw propeller at the lower part of the hopper for premixing with clean water, the wetted material enters the preparation tank for dilution and mixing, and is prepared according to the concentration required by the user.

The preparation solution enters the storage tank from the preparation tank through the aging tank. When the liquid level in the storage tank is at a high level, the preparation process stops automatically, and when the solution drops to a low level, the batching process starts automatically. Both the preparation tank and the curing tank are equipped with agitators to fully ensure the dilution and curing of the medicine. The preparation flow and concentration can be determined by adjusting the water inlet flow and adjusting the speed of the screw shaft.

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.
