However, due to the chemicals' persistence in the environment, drinking water can become contaminated with long-chain PFAS (eight or more carbon atoms in a molecule), a group that includes PFOA and PFOS. This is one of the primary concerns of human and animal exposure to the substances, acc...
Perfluorooctane sulfonic acid (PFOS) Both are part of a man-made chemical group called per- and polyfluoroalkyl substances (PFAS). Recently announced regulations, water safety updates and other information have made it important to understandwhat these PFAS chemicals areand how they could end up ...
Water consumption in the production of clothing can be astronomical – 1000 litres (4 bathtubs) for a cotton t-shirt, 7000 litres (26 bathtubs) for ... March 18, 2019 Designing the Argonaut and Atalanta Waterproof Jackets 'Entry-level' waterproof clothing is all-too-often overlooked. We’...
Dubbed “forever chemicals,” PFAS chemicals don't break down easily over time and dissolve in water. Because of that, some scientists are concerned that these chemicals could build to levels that could harm the environment -- and your body. While there are studies that show evidence of this,...
This just in, in early 2020, the EPA announces a “proposed decision” to regulate PFOA and PFOS in drinking water. Even though that sounds a bit vague and maybe non-committal, it seems to be a step in the right direction for US citizens. ...
Since PFOA and PFOS in drinking water is hazardous to human health, EPA suggests the removal of these contaminants from drinking water. This post introduces PFOA and PFOS, their impact on human health, and methods to remove them from drinking water.PFOA and PFOS What Are PFOA and PFOS?
filtration compared to granular media. Catalytic and activated carbon are combined to perform ion-exchange and sub-micron filtration — down to 0.5 microns. This works to reduce contaminants like lead, cysts, PFOA/PFOS, chlorine, chloramines, and much more for amazing water throughout your entire...
PFOA is perfluorooctanoic acid. PFOS is Perfluorooctane Sulfonate. Both are chemicals commonly found in drinking water. They are associated with cancer, immunity deficiencies, and thyroid imbalances. Chloramines are disinfectants used by water utilities to treat drinking water. TheEPAhas studied the healt...
Companies in this area would have to rethink their strategies since PVDF is even more dominant here than in the potable water sector. Chinese manufacturers have a strong position in MBR technology and many products are made solely for use within their domestic market. Although the China local ...
PFAS accumulates in the body, which is why EPA set their limits for drinking water at 4 parts per trillion for two common types _ PFOA and PFOS — that are phased out of manufacturing but still are present in the environment. Health experts say low doses of the chemicals can build ...
