Technical cleaning of PFOA/PFDA contaminated foam concentrate systemsNatusch & Thiedemann specialises in the technical cleaning of tank installations and pipework. Due to the very specific limit value, this can best be described as "laboratory cleaning".
Natusch & Thiedemann are specialised in the technical cleaning of PFOA / PFDA contaminated foam agent tank systems and raw pipelines. The term "technical cleaning" is not necessarily familiar to many people. However, based on the very specific threshold value, this term would have to be replaced by "laboratory cleaning". This is because the aim of cleaning is not only to clean the system, but to make it limit value-free. This means reducing the plant load from 500 or 1200 ug PFOA to less than 10 ug. It is easy to imagine that this is not an easy task from a technical point of view. 30ug per 1 litre of water cannot be detected by the human senses. Neither the sense of smell nor the sense of sight can detect an increased value. Taste, perhaps, but you should not try this with PFOA, because even small amounts of PFOA in the blood accumulate in the body over many years and can cause considerable damage.
