Some contaminants are difficult to remove with high pressure. Rust, lime scale and some product residue can be better removed dissolving them using a chemical product. This technique is called chemical cleaning. Smet Jet has many years of experience in cleaning using chemicals (and in surface treatment) for industrial contaminated systems and installations.
First, we determine the most suitable chemical product and concentration for the cleaning during a test phase. This product will be pumped through the system or installation to be cleaned through a closed circuit until the contaminant has been fully removed. Next, the system or installation will be flushed so that all chemical residues are removed. This technique is also applied before new systems and installations are commissioned to remove protective coatings. Smet Jet has performed chemical cleaning of boilers all over Europe and Eskom.
