Measures to Address PFAS | Initiatives for Innovation
Proposing solutions based on high-sensitivity and multi-component analysis, in light of the global trend toward stricter regulations
Introducing the Kurita Group's initiatives on PFAS.
About PFAS
PFAS refers to a collective term for synthetic organic fluorine compounds, with over 10,000 substances said to exist. Due to their water and oil repellency, as well as high chemical and heat resistance, they are used in a wide range of products, from industrial to consumer goods.
However, among PFAS, three types—PFOS, PFOA, and PFHxS—have been designated as "specific PFAS" due to concerns about their persistence in the environment and potential health effects, leading to water quality and manufacturing regulations in recent years, primarily in Europe and the United States. In Japan, water quality standards for PFOA and PFOS, which have been confirmed to be harmful among PFAS, have been established for tap water, and regular inspections will be mandated starting from fiscal year 2026.
Responding to the global movement towards stricter regulations
The Kurita Group can analyze and examine the water quality and circumstances of the water used (process water) and discharged (wastewater) at our customers' factories, providing appropriate proposals and support for responding to and treating PFAS.
Utilizing ultra-pure water analysis skills and expertise in trace analysis, we develop and provide solutions that include water quality analysis down to concentrations as low as 0.1 ppt*. We also develop and offer solutions for visualizing PFAS risks through multi-component analysis, removing and separating PFAS using activated carbon and reverse osmosis (RO) membranes.
- An acronym formed from the initial letters of "parts per trillion," indicating the ratio of how much out of one trillion.
Towards providing comprehensive solutions
The Kurita Group aims to provide comprehensive solutions that encompass the analysis, removal, and neutralization of PFAS, a significant social issue. In addition to the solutions currently being developed, we are working on further improving monitoring technologies and developing neutralization technologies designed for the optimal treatment of PFAS removed from the environment.
Furthermore, in anticipation of future strengthened regulations, we will also promote joint research and development with material manufacturers and others to advance the practical application of PFAS-free materials for valves, piping, and other components of water treatment equipment.
