Chemical dosing tanks, also known as chemical storage tanks or chemical feed tanks, are containers used to store and dispense various chemicals in industrial, water treatment, and chemical processing applications. These tanks are designed to safely store and handle a wide range of chemicals, including acids, bases, solvents, and other corrosive or hazardous substances. 

Chemical dosing tanks

Features and uses of chemical dosing tanks:

  1. Material: Chemical dosing tanks are typically made from materials that are resistant to corrosion and chemical degradation, such as polyethylene (PE), polypropylene (PP), or fiberglass-reinforced plastic (FRP). The choice of material depends on the specific chemical being stored.

  2. Capacity: These tanks come in various sizes and capacities, ranging from a few gallons to several thousand gallons, depending on the application's requirements.

  3. Design: The tanks are designed to be leak-proof and to prevent the escape of fumes or vapors. They may have features like double-walled construction or containment basins to provide an added layer of protection against leaks.

  4. Mixing and Dispensing: Chemical dosing tanks often come equipped with mixers or agitators to ensure proper mixing of the chemicals before they are dosed into a process. Dispensing systems can be manual or automated, depending on the application.

  5. Safety: Safety features, such as venting systems, pressure relief valves, and level indicators, are incorporated to prevent over-pressurization or overfilling of the tanks.

  6. Dosing Pumps: Chemical dosing tanks are usually paired with dosing pumps or metering pumps to accurately and consistently deliver the chemicals into the process or treatment system.

  7. Applications: Chemical dosing tanks are used in a wide range of industries and applications, including:

    • Water treatment: for the addition of chemicals like chlorine, coagulants, and pH adjusters in drinking water and wastewater treatment plants.

    • Chemical manufacturing: for storing and dosing raw materials or intermediates in chemical production processes.

    • Agriculture: for fertilization and pesticide application in farming.

    • Industrial processes: for controlling pH levels, corrosion inhibition, and other chemical treatments.

    • Oil and gas: for chemical injection into wells for enhanced oil recovery and corrosion control.

  8. Maintenance: Regular inspection and maintenance are crucial to ensure the integrity of the tanks and the safe handling of chemicals. This includes checking for leaks, corrosion, and wear and tear of components like valves and pumps.

  9. Regulations: Depending on the location and the type of chemicals being stored and dispensed, there may be regulations and safety standards that must be followed, including guidelines for tank design, material compatibility, and safety measures.

It's important to choose the right type of chemical dosing tank for your specific application, considering factors such as the chemical properties of the substances being handled, required capacity, and safety requirements. Consulting with experts in chemical storage and handling is advisable to ensure compliance with safety and environmental regulations.
