FILTRACIJA
Defirezatori
| Uklanjanje željeza, mangana i H2S iz vode predstavlja važan zadatak u pročiščavanju vode, jer oni mogu graditi netopive hidrokside koji mogu ugroziti vitalne dijelove sistema za pročiščavanje. Obično je gornja granica sadržaja željeza u vodi za piće 0.3 mg/l, a mangana 0.05 mg/l. Deferizatori rade na principu oksidacije otopljenog dvovalentnog željeza i mangana u njihov trovaletan oblik koji je netopljiv i separabilan. Za potrebe formiranja deferizacijskih uređaja koristimo razne vrste filtracijskih medija u zavisnosti od osobina same vode i želja korisnika. Koristimo filtracijske materijale kojima se radni vijek produžava regeneracijom ali i one koje je dovoljno samo protu strujno isprati. |
