Polymer preparation devices are automatic systems used to dissolve powder polymers in water to achieve the desired viscosity and active substance ratio. These devices are critical for the efficient operation of sludge dewatering, coagulation-flocculation, chemical treatment and DAF processes. Fully automatic control systems ensure the preparation of polymer solution in the correct ratio and provide continuous, homogeneous and stable feeding to the process. Our company produces polymer preparation units in standard capacities of 1 m³, 2 m³, 3 m³, 5 m³ and 10 m³, as well as project-based custom sizes with stainless steel, PP or HDPE bodies.
The system typically operates through a three-stage process:
Dry or liquid polymer is first mixed with water.
The mixture is homogenized with a low-speed mixer for a certain period.
Ready-to-use polymer solution is fed to the treatment process via dosing pumps.
During the preparation process, water flow rate, mixing time and dosing ratio are automatically regulated under PLC control. This guarantees that a solution with the same active substance ratio is always obtained.

Polymer preparation devices are among the most critical chemical preparation units in treatment plants. Producing polymer solution in the correct viscosity and stable form directly determines flocculation and dewatering performance. Polymer preparation systems produced by our company are specially designed for different needs with high mixing efficiency, precise dosing control, advanced automation features and rich accessory options. Thanks to vibration motors, heater jackets, auger feeding systems, slow-speed mixers in maturation chambers and smart control panels used in dry polymer hoppers, the system works in a fully integrated manner. This ensures stable, reliable and economical polymer solution preparation under all conditions. With their compact structure, easy maintenance capability and long-lasting design, our polymer preparation devices have become an industry standard in chemical feeding technology of modern treatment plants.
