| abstract |
(57) Abstract: The present invention relates to the effluent of a photographic processor, and more specifically, the effluent of a processor for rinsing material, which effluent also contains gelatin. It provides a particularly suitable method for removal. The present invention is a method for purifying wastewater containing a silver compound; (1) a salt of poly (guanidine) polymer or poly (biguanidine) polymer is added to the wastewater, and (2) a flocculant. Is added, and then (3) the generated aggregate is filtered. The most preferred poly (guanidine) compound is poly (hexamethyleneguanidine) hydrochloride. |
