Filtration Weekly is WFI’s quick scan of what matters to filtration professionals—technology, testing/evaluation, standards, major industry events, and business/market moves—plus what to watch next.
This week’s highlights (Jan 22–28)
1) PFAS: new LDH material reports “up to 100× faster” capture (research watch)
Rice University research on a copper–aluminum layered double hydroxide (LDH) material said to capture certain long-chain PFAS much faster than commonly used media, with a pathway to concentrate PFAS for downstream destruction. Read more.
2) Water filtration: GE brings refrigerator water filter production in-house
GE Appliances announced its first-ever in-house refrigerator water filter manufacturing operation at Appliance Park (Louisville, KY), emphasizing tighter control over design/testing/manufacturing and stronger anti-counterfeit measures. Read more.
3) Microplastics testing: scientists call for more rigorous, standardized methods
Scientists from more than 20 institutions are calling for “more rigour” in how tests for microplastics in the human body are conducted, noting risks of overstating results without stronger controls and multi-method confirmation. Read more.
4) Water treatment membranes: microfiltration fouling control for high-turbidity raw water (peer-reviewed)
A newly posted ACS ES&T Water paper examines precoat-microfiltration for high-turbidity raw water and discusses practical fouling-control mechanisms for real-world engineering applications. Read more.
5) PFAS beyond drinking water: lawsuit challenges EPA approval of PFAS-classified insecticideCoverage this week reports public health and environmental groups suing the U.S. EPA over approval of isocycloseram, described as a PFAS “forever chemical,” increasing scrutiny of PFAS use and oversight beyond water treatment.
