Abstract

Przedmiotem wynalazku jest sposób wstępnej regeneracji chromowych ścieków garbarskich, obejmujący proces filtracji, w tym mikrofiltrację i ultrafiltrację. Sposób charakteryzuje się tym, że przeprowadza się następujące etapy: a) najpierw surowe ścieki garbarskie poddaje się wstępnej filtracji z eliminacją grubej zawiesiny, następnie b) otrzymany filtrat poddaje się mikrofiltracji, przy czym permeat zbiera się w zbiorniku, po czym c) otrzymany permeat poddaje się ultrafiltracji z wytworzeniem recyrkulatu chromowego, ewentualnie prowadzi się następny etap d) w którym recyrkulat chromowy poddaje się nanofiltracji.
