Pioneering work for clean water<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Per- and polyfluoroalkyl substances (PFAS) are among the most persistent and harmful pollutants of our time. They accumulate in the soil and groundwater - and thus end up in our food and drinking water.<\/p>

A particularly critical entry path is the use of fluorine-containing foam extinguishing agents - for example during firefighting operations or by triggering fixed fire suppression systems. Even a single application can be enough to introduce PFAS into the ground over a large area.<\/p>

The result: long-term contamination of the groundwater, which poses a serious risk to people and the environment. Targeted and effective remediation of this damage is therefore essential in order to sustainably protect our environment and preserve our health.<\/p>

Cornelsen has taken on this challenge \u2013 with a solution that sets new standards worldwide: the PerfluorAd\u00ae process. This patented technology targets PFAS from contaminated water, in a cost-effective and demonstrably successful way \u2013 even in highly contaminated sites.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

PerfluorAd\u00ae process<\/h2>\t\t\t\t<\/div>\n\t\t\t\t

The patented PerfluorAd\u00ae process is based on a liquid active ingredient that reacts with the PFAS in the system and forms stable flocs. These can be removed from the water by filtration or sedimentation. The advantage: cleaning is efficient, gentle on the material and without the disadvantages of adsorption. The rinse water is also treated directly on site, which minimises transport and disposal costs.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Firefighting water<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Data from laboratory tests and corresponding treatment applications on site have shown that the treatment of firefighting water poses a particular challenge. This water can contain high PFAS concentrations, organically bound fluorinated compounds (so-called precursors), particles such as soot and\/or surfactants. Such a combination of substances has a negative effect on sorption processes such as granular activated carbon (GAC) or ion exchangers (IX). This can result in premature or even immediate breakthrough of the filter material.<\/p>

A treatment method that combines the removal of PFAS in a precipitation step with subsequent adsorption for fine purification can optimize the treatment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
