Integrated Polymer Preparation Unit Dosing Variable Frequency Dosing Device QXYTH-3000L

The integrated polymer preparation unit dosing variable frequency dosing device is an advanced automation system designed for precision chemical dosing in water treatment, wastewater management and industrial processes. It integrates polymer preparation and dosing into a single unit, using variable frequency drive (VFD) technology to dynamically adjust pump speed to ensure accurate and efficient delivery of chemicals based on real-time demand. The system enhances process control, reduces energy consumption, and minimizes chemical waste. Key features include an integrated programmable logic controller (PLC), an easy-to-operate touch screen interface, and durable, corrosion-resistant materials.

◈

The QXYTH-3000L Integrated Polymer Preparation Unit is a high-capacity, fully automated system engineered for large-scale polymer solution preparation and dosing in municipal water treatment, wastewater treatment, and heavy industrial applications. The system integrates powder polymer storage, automatic volumetric feeding, dual-stage dissolution/maturation, and variable frequency controlled dosing into a single skid-mounted unit. The 3000L dissolving tank, with dimensions of L2600 × W1220 × H1200 mm, provides the largest capacity in the QXYTH series, enabling extended continuous operation for high-demand facilities. The advanced mixing system features a high-speed dispersion impeller for initial powder wetting combined with a low-speed maturation agitator for complete polymer chain activation, achieving optimum flocculation performance. The integrated variable frequency drive enables precise dosing pump speed control, responding to 4-20mA process signals for automated flow-based polymer dosing. With a total power consumption of only 2.97 kW, the QXYTH-3000L delivers exceptional energy efficiency for high-volume polymer preparation.

Frequently asked questions
◈ What is the capacity advantage of the 3000L model over smaller units?
The 3000L tank provides 50-100% more capacity than smaller models (1000-2000L), enabling extended continuous operation for large-scale facilities. This reduces batch preparation frequency and ensures uninterrupted polymer supply for high-demand applications such as municipal sludge dewatering and industrial clarification. The larger tank also improves mixing efficiency for high-viscosity polymer solutions, typically achieving 96-98% polymer activation.
◈ How does the dual-stage mixing system improve polymer performance?
The dual-stage system features a high-speed dispersion impeller that rapidly wets and disperses the polymer powder, preventing fish-eye formation and agglomeration. The slow-speed maturation agitator then provides gentle, extended mixing for complete polymer chain unwinding and activation. This two-stage approach typically achieves 96-98% polymer activation efficiency, compared to 70-80% with single-stage mixing, resulting in lower polymer consumption and improved flocculation performance.
◈ What is the typical polymer dosing capacity?
The QXYTH-3000L provides typical polymer dosing capacity of 300-1800 L/h of 0.1-0.5% solution, depending on polymer type and molecular weight. The 3000L tank supports batch volumes up to 3000L, enabling 3-12 hours of continuous operation at typical dosing rates. Jiangsu Aozheng Metal Products Co., Ltd. provides capacity calculations based on specific application requirements and polymer characteristics.
◈ What after-sales support is available?
Jiangsu Aozheng Metal Products Co., Ltd. provides comprehensive after-sales support including installation supervision, operator training, and ongoing technical assistance. Spare parts including screw feeder assemblies, mixing impellers, seals, and VFD components are available with typical delivery of 7-15 days. Annual maintenance contracts and remote monitoring support are available for large-scale installations. The company has supplied polymer preparation units to projects across the United States, Germany, Australia, Canada, and the Middle East.
