Abstract

Przedmiotem zgłoszenia jest sposób wydzielania chromu ze ścieków, w tym ścieków garbarskich, w wyniku reakcji podwójnej wymiany tworzą się nierozpuszczalne sole chromu i kwasów organicznych, które dają się bardzo łatwo odfiltrować i tą drogą wydzielić chrom ze ścieków. Zebrane osady soli chromowych pewnych kwasów organicznych poddawane są następnie regeneracji.
