Polymer Preparation System

A polymer preparation system is a fully integrated unit that automates the process of dissolving, aging, and dosing polymer solutions. It is designed to prepare polymer solutions from either dry polymer powders or liquid concentrates, ensuring the correct concentration and activation before dosing into the treatment process.

These systems are widely used in:

• Municipal and industrial wastewater treatment plants
• Sludge dewatering and thickening processes
• Drinking water treatment facilities
• Paper and pulp industries
• Food and beverage processing plants

By providing a controlled and continuous supply of activated polymer, they play a crucial role in optimizing separation efficiency and reducing chemical waste.

The polymer preparation system operates in a continuous and automatic cycle:

1. Feeding: Dry or liquid polymer is accurately fed into the mixing tank.
2. Dissolution and Mixing: The polymer is blended with water under controlled conditions, ensuring complete dissolution.
3. Activation and Maturation: The solution passes through aging zones to allow full activation.
4. Dosing: The prepared polymer solution is then delivered to the process line by a polymer dosing unit or metering system for polymers, ensuring the correct amount is used for optimal performance.

This continuous process guarantees a stable and ready-to-use polymer solution at all times, without operator intervention.

A typical polymer preparation station consists of the following key components:

• Polymer storage and feeding unit: For dry polymer make down systems, a volumetric or gravimetric feeder ensures precise powder dosing. For liquid polymers, metering pumps are used.
• Mixing and activation tank: Multi-stage tanks with agitation zones guarantee proper hydration and activation of the polymer solution.
• Aging and maturation chamber: Allows the polymer chains to fully uncoil and reach maximum effectiveness.
• Polymer dosing system: Includes metering pumps, flow meters, and control valves for precise delivery into the process line.
• Control panel and automation unit: Offers easy operation, remote control, and integration into existing plant control systems.

Polymer preparation systems are used across a wide range of water and wastewater treatment applications, including:

• Sludge dewatering: Works seamlessly with centrifuges, belt presses, and screw presses to improve floc formation and water release.
• Primary and secondary clarification: Enhances settling performance and improves effluent quality.
• Industrial process water: Ensures stable polymer dosing for consistent process results.
• Paper & pulp, mining, and food industries: Optimizes chemical usage and improves solid-liquid separation efficiency.

Dry Polymer Make Down Systems

For applications using powdered flocculants, dry polymer make down systems provide efficient hydration and activation. These systems integrate a dry polymer feeder, wetting cone, and multi-stage mixing tank to ensure thorough dispersion and avoid clumping, maximizing polymer performance and minimizing waste.

Automatic Polymer Preparation Unit – Smart and Reliable

An automatic polymer preparation unit offers plug-and-play functionality, precise control, and minimal operator attention. With integrated sensors and intelligent dosing algorithms, these units deliver reliable polymer preparation and dosing performance even under variable flow conditions.
