Industrial Tank Cleaning

What are the different kinds of tanks that need tank cleaning service? We describe three types that might be found in your facility. If you do have them, you may want to keep reading to see if any of these clean-up or maintenance services from TRC are right for you.

1) Neutralization Tanks

Neutralization tanks are attached to sewer lines and serve to neutralize any acids prior to discharging into the sewer system.  Even if no acids are being sewered, the tanks still fill up with sediment and can clog over time. 

Here is a diagram of a tank to give you a better idea of how they work. Our service includes removal of old rock/sludge, packaging, testing, disposal, and installation of new rock. The old rock/sludge can have enough heavy metals built up to be regulated as hazardous waste, testing will inform that process.

2) Holding Tanks

Holding tanks are used in all kinds of manufacturing processes. Anytime a manufacturer has large quantities of liquid product that they need to hold and use continuously they’re likely to have some sort of tank system for storage. The tanks are used to store a product necessary for the manufacturing process. Regardless of the product, these tanks will occasionally need to be cleaned out to remove sedimentary buildup, impurities, and to check the tank integrity. Often times, holding tank work is completed during regular plant closures in order to avoid interrupting the manufacturing process. 

If your facility is operating a boiler, you likely have back-up fuel holding tanks. The size of the back-up tank is dependent on the size of your boilers.

PROJECT EXAMPLES

Demolition Project:

  • Clean-out of four 2,500 gallon ink tanks, one 10,000 gallon fuel oil tank, two 5,000 gallon acid tanks
  • Clean all associated process lines
  • All tanks required confined space entry and appropriate PPE

Tank Clean-out:

  • Clean-out of one 10,000 gallon sulfuric acid tank and one 10,000 gallon sodium hydroxide tank
  • Waste neutralization
  • No confined space entry

 

3) Maintenance Equipment/Tanks

If your facility operates a boiler, it’s likely you have back-up fuel tanks to continue operation in the absence of municipal gas. Virtually every school and multi-story office building is operating a boiler. 

These tanks vary greatly in size depending on the size of the boiler. Many facilities are switching from #6 fuel oil to #2 fuel oil. If this is happening in your facility, the old #6 tanks need to be cleaned out before they can be decommissioned. Additionally, the #2 fuel oil tanks may require maintenance due to contamination or repurposing of tanks. 

PROJECT EXAMPLES

Underground Tank Clean-out, Large

  • Clean-out one 325,000 gallon underground fuel oil tank
  • Tank contained both #6 and #2 fuel oil
  • Required confined space entry and appropriate PPE

Underground Fuel Tank Removal, Small

  • Removal of one 1,500 gallon underground fuel oil tank
  • Tank contained #2 fuel oil
  • No confined space entry
