TechXtract® from Matom
The TechXtract® process from Matom uses controlled chemical reactions in successive steps to remove contaminants from the surface and subsurface of materials such as metal and concrete.
TechXtract® is most frequently the best solution when one or more of the following conditions prevail:
- Multiple contaminants are to be removed in one process, such as chemical compounds and radionuclide fingerprints.
- Other methods are ineffective due to leach back and depth of contamination.
- The residual contamination level required is very low (e.g. for safe re-use of item).
- The item has a high scrap/re-use value.
- Waste minimisation objectives require a high volume of free release and very low volume of contaminated materials.
- There are Health and Safety or engineering constraints limiting the use of alternative methods (e.g. flammability, airborne contamination, toxic/explosive gases or corrosivity).
- The contaminated surface is a challenging configuration (e.g. equipment such as valves, internal pipework).
The TechXtract® decontamination solution is provided as a fully managed service.
The type of contamination determines how the TechXtract® process is applied. For example, on large surface areas, such as concrete, our specialist operators apply each sequential chemical formulation as a fine mist which is mechanically agitated, allowed to dwell for a determined period, rinsed and vacuumed. On smaller targets, the TechXtract® decontamination process is enhanced with ultrasonics in order to reduce dwell times and increase throughput.
Contaminant levels are reduced by up to 90% per cycle. The duration and total number of cycles is determined from initial contaminant concentrations and final concentration target levels.
Waste is neutralised then stabilised using grouting or absorbent polymer. The waste product can also be incinerated.
