How to Clean and Maintain Chemical Storage Tanks

Are you struggling with how to clean chemical storage tanks? If so, you’re not alone.

Chemical storage is typically complicated. In many cases, you’ll want to ensure that the tanks you use are food-grade. At the same time, you’ll want to pay attention to contaminants.

To learn more about how to clean and maintain chemical storage tanks, keep reading.

Assessing the Condition of Used Tanks Before Cleaning

The most important step in learning how to clean and maintain used chemical tanks is assessing the condition of the tanks before cleaning. This should be effectively done to determine if the tank is still safe to use or if it needs to be generally replaced.

Finally, the tank should be thoroughly dried before it is often filled with new chemicals and ready for use. Taking the time to properly assess the condition of used tanks before cleaning can help avoid unexpected problems and ensure a safe and successful cleaning process.

Gather Necessary Supplies and Safety Equipment

It is important to gather the necessary supplies and safety equipment before cleaning and maintaining a used chemical storage tank. Protective safety glasses and gloves are a must to protect against hazardous chemicals.

Additionally, you should wear a face shield or respirator mask to protect against fumes. A power washer, scrub brush, and non-abrasive detergent should be generally used to remove any debris or contaminants.

You should use a safety ladder to ensure easy access for maintenance. To prevent further corrosion, you can apply tank coatings using a paint sprayer or brush.

You should also conduct regular inspections to assess the integrity of the tank for any further repairs or maintenance required. This will help to ensure the tank runs at optimal efficiency.

Remove Buildup from the Interior of the Tank

Removing any buildup from the interior of the tank is vital. The tank should be often drained and all residue flushed with solvent, hot water, or detergent before cleaning.

The interior of the tank should then be usually scrubbed to remove any residue that has accumulated over time, being especially thorough in areas that have not been previously cleaned.

Once all the residue has been typically removed, rinse the interior of the tank with hot water, then inspect for any damage that was often caused by buildup. 

Utilizing Disinfectants to Kill Microbes

Utilizing disinfectants to kill microbes should be a priority. Disinfectants that include these components are suitable options:

  • Chlorine and phenols
  • Quaternary ammonium compounds
  • Iodophors

Furthermore, it is important to follow the product instructions carefully to maximize their effectiveness. Once the disinfectant has been added to the tank, allow it to sit in the tank for the recommended time outlined in the instructions.

Following this, it is important to fully rinse the tank and allow it to air dry before refilling it. Utilizing disinfectants to kill microbes is essential for properly cleaning and maintaining used chemical storage tanks.

Monitor and Test Water Quality

To ensure the safety of stored chemicals and water, it is important to monitor and test used storage tanks. Test the water for quality and pH levels. Proper testing equipment should be used to ensure accuracy of the results.

Any contaminants or impurities should then be removed by either treating or replacing the water. Disinfectants can also be used to clean and deodorize the tanks, and you should monitor them regularly for any signs of contamination.

Finally, the storage tanks should be re-inspected for physical damage and corrosion. Proper cleaning and maintenance of used chemical storage tanks will help to ensure that your chemicals and water are safe and free from contamination.

Make Necessary Repairs to Tank Structure and Accessories

When it comes to the maintenance and repair of used chemical storage tanks, safety is paramount. For any potential damage or corrosion, make sure to do the following:

  • Inspect the tank
  • Inspect all accessories
  • Inspect the piping

If any are generally found, make the necessary repairs according to manufacturer instructions. Additionally, replace any gaskets, valves, clamps, or other components that may have worn over time.

Following these steps can help ensure a long-lasting and safe chemical storage tank.

Utilize Corrosion Resistant Coating

The most effective way to reduce corrosion is to apply a corrosion-resistant coating. This can be done either manually or with the help of a professional. The degree of compatibility will depend on the following:

  • Substrate
  • Ambient environment
  • Water exposure

Regardless, the coating should be applied in multiple layers to ensure a long-lasting, uniform protective finish. The outermost layer should be a chemical-resistant, clear polymer-based coating to ensure the adhesion of future coats.

To ensure optimal performance, the application should be regularly inspected and reapplied annually or as necessary.

Properly Store Used Chemicals

Before buying used chemical tanks, it is important that you know how to clean and maintain them properly. This is to make sure that the chemicals stored don’t corrode, degrade, or become contaminated.

Non-chemical-resistant parts of the tank should be removed and kept separate, then the interior of the tank should be cleaned and rinsed thoroughly to get rid of any residual chemicals and contaminants.

Once the tank has been properly rinsed and cleaned, it should be inspected for structural integrity. Additionally, stainless steel tanks should be sealed with corrosion-resistant paint.

Then, make sure that the chemicals being typically stored are compatible with the material the tank is often made from and the environment it is being stored in.

Lastly, properly store the used chemicals by securely capping all containers and storing them in designated areas that are away from direct sunlight and not prone to leaks. 

Disposing of Chemical Contaminants Safely

It is important to characterize the waste and to research local laws and regulations prior to disposal of the chemicals. It is important to use proper methods to dispose of any hazardous waste, such as:

  • Landfilling
  • Incineration
  • Recycling

For small amounts, disposing of chemical waste down a drain is also possible if the local sewer treatment facilities are typically equipped to handle it.

You must also properly dispose of all unused or expired chemicals. It is important to research the correct disposal methods for each chemical to ensure that the environment is not harmed.
