A filtration arrangement for removing PFAS contaminants from water is described. nThe filtration arrangement includes at least one first filtration cartridge and at least one nsecond filtration cartridge arranged for series flow therethrough. The first filtration ncartridge comprises a first filtration body having a first filtered water outflow port, a first ninflow port for receiving influent water or for receiving filtered water from the first nfiltered water outflow port of an immediately preceding first filtration cartridge, and a nfirst filtration media contained within the first filtration body, said first filtration media ncomprising a mixture of calcined attapulgite clay, activated carbon and, optionally, a nkinetic degradation fluxion media (KDF). The second filtration cartridge comprises a nsecond filtration body having a second filtered water outflow port, a second inflow port nfor receiving filtered water from the first filtered water outflow port of an immediately npreceding first filtration cartridge or from the second filtered water outflow port of an nimmediately preceding second filtration cartridge, and a second filtration media ncomprising an ion exchange resin and optionally activated carbon, contained within the nsecond filtration body.n10 n66 6 18 n60 .. . .. .54.. . n5 6. ~. .......... 6 n50 n44ai 44b n26 20' 12 |
