Tank Cleaning in Operation

​

The use of a Remotely Operated Vehicle (VRO) allows visual inspection and cleaning to be carried out while the tank is still in operation, without water quality being affected.

​

For fire fighting systems, the technique meets the requirements of standard NFPA 25 items 9.2.6.1.1 and 9.2.6.1.2.

​

Cleaning aims to bring reliability to the system, avoiding clogging of sprinklers, the proliferation of biodiversity and changes in the pH of the water, which can accelerate the corrosion process.

​

It is possible to apply this technique to various water storage systems, such as:

​

• Fire fighting

• Cooling tower

• Process

• Treated

• Gross

Sediments: Geobags

​

The sediments removed along with the water can be separated through the use of geobags.

In this process, water leaks through the fabric and residues accumulate inside the blanket, allowing clean water to return to the equipment being cleaned (cooling towers, tanks, etc.).

The technique can be applied as long as a test has been carried out to analyze the granulometry of the sediments.
