New Breakthrough | PFAS Removal Technology Passes SGS International Authoritative Testing

In December 2023, Japanese media reported that some residents in Japan had abnormal blood test results. After investigation, it was found that this was related to the long - term consumption of tap water containing high concentrations of per - and polyfluoroalkyl substances (PFAS) by the residents.

In August 2024, Australian media reported that PFAS was detected in water samples from multiple drinking water catchment areas in the Greater Sydney region.

In October 2024, the US Geological Survey released a research report: Groundwater in the United States is severely polluted, and the drinking water of approximately 71 million to 95 million people may contain carcinogens. Water is regarded as the main source of human exposure to PFAS.

In 2025, the EU will see a revision! The control requirements for PFAS substances will be more explicit. They called for the expeditious proposal of clearer and more predictable initiatives to restrict the application of PFAS substances in a wide range of consumer products and industrial uses.

In recent years, news reports about the presence of per - and polyfluoroalkyl substances (PFAS) in drinking water around the world have, like heavy hammers, struck the public's sensitive nerves regarding water quality safety. PFAS pollution has transcended national boundaries and become a global pollution problem that urgently needs to be overcome!

Against this backdrop, Culax has developed a technology capable of effectively removing PFAS and passed the SGS international authoritative testing. As a guardian of the public's healthy drinking water, Culax is committed to the innovative research and development of PFAS removal technology. After numerous painstaking studies and rigorous tests, it finally developed a filter element technology that can efficiently remove PFAS. This technology is not only applicable to drinking water purification but can also be effectively applied to various life scenarios such as bathing and washing. The water purification filter element developed using this technology has passed the SGS international authoritative testing, and its removal effect has met the NSF/ANSI 53 standard.

To verify the removal effect of the developed sintered activated carbon functional filter element for PFAS removal on these two substances, Culax commissioned SGS to conduct a full - scale spiking test in accordance with the NSF/ANSI 53 - 2022 standard, and detect the contents of PFOA and PFOS in the filtered water samples under different filtration fluxes. The results showed that after treating 7 tons of spiked water samples, PFOA and PFOS were not detected (ND) throughout the process in the filtered water samples. This further indicates that the removal effect of this filter element on PFOA and PFOS also meets the NSF/ANSI 53 - 2022 standard.

This test result fully demonstrates the excellent performance of the sintered activated carbon functional filter element for PFAS removal in removing harmful substances such as PFAS from water, providing consumers with a safer, more convenient, and healthier water purification solution. The development of this technology is not only a strong response to the current market demand, but also an important milestone achieved by Culax in the water purification field, helping the industry to advance towards a higher technical level and better product quality.
