High Quality PE Industrial Storage Water tank Plastic Chemical Dosing tank For Dosing System

Dosing tank is the core component of any chemical feed system. Also known as a chemical day tank or mixing tank, it is designed for the safe storage, preparation, and controlled injection of treatment chemicals. These tanks ensure precise chemical metering into processes like water treatment, manufacturing, and cooling systems.

Key applications include:

• Water & Wastewater Treatment: For disinfectant, pH adjustment, and coagulant dosing.
• Chemical Processing: Accurate reactant addition for consistent product quality.
• Cooling Towers & Boilers: Dosing scale and corrosion inhibitors to protect equipment.

Why choose a professional dosing tank?

• Corrosion-Resistant Materials: Constructed from HDPE, PP, or FRP to handle aggressive chemicals.
• Integrated Features: Options include agitators, level sensors, and containment bunds for safety.
• Precision & Reliability: Ensures accurate chemical dosage, reducing waste and operational costs.

The Principle of Controlled Metering and Injection

The tank works in concert with other components. These include mixers, level sensors, and dosing pump. The tank itself facilitates several key functions:

• Solution Preparation: Chemicals are often diluted to a specific concentration within the tank.
• Storage and Buffer: It provides a buffer volume, preventing pump run-dry situations.
• Safe Containment: It safely houses potentially hazardous liquids.

In essence, the chemical solution tank transforms raw or concentrated chemicals into a ready-to-use, precisely controllable resource.

Integral Features for Enhanced Performance and Safety

Modern chemical feed tanks are not bare vessels. They incorporate intelligent features for optimal operation:

• Agitation Systems: Built-in mixers ensure the solution remains uniform. This prevents sedimentation and stratification. Consistent concentration is the goal.
• Level Monitoring: Ultrasonic or float switches provide real-time data on chemical volume. This allows for timely refills and can trigger automated alerts.
• Containment Bunding: Many tanks feature an integral bund or spill basin. This secondary containment captures any potential leaks. It is a critical safety feature for environmental protection.

These features transform a basic tank into a smart, reliable component of your process automation.

Precision Control Systems: Integrating Tanks with Dosing Pumps

A tank alone cannot dose. Its true potential is unlocked when paired with a precision metering pump. This integration creates a complete chemical dosing skid. The tank stores the solution; the pump delivers it with exactitude.

Achieving Unmatched Accuracy with Modern Technology

How is this accuracy achieved? The pump draws from the tank. It then injects a precise volume of chemical into the process line. Modern control systems manage this integration flawlessly.

• Flow-Paced Control: The injection rate is proportional to the flow rate of the main process stream.
• Feedback Control: A sensor (e.g., a pH probe) monitors the process. It sends a signal to the pump to adjust the dose in real-time.

This synergy between the chemical storage tank and the pump is what delivers true process optimization. It moves operations from manual guessing to automated, data-driven precision.
