Penerapan dasar perhitungan kebutuhan katalisator untuk oksidasi sulfida

Sulphides beared in tannery wastewater are harmful pollutant which beturned to disastrous hydrogen sulphide gas under acidic circumtances. The previous study on Sulphides Oxydation System of varied catalist (MnSO4) added has not indicated a satisfactory result yet. The main objective of this study is to verify the merit of Mn++ dosage based on the sulphides content. Futher, whether or not it will be useful to optimize the oxydation process and economize the daily cost of tannery wastewater treatment. The data of sulpides content monitored during 12 hours oxidation period showed that there was significant difference between the curve (sulpides vs time) with Mn++ and the curve without Mn++ treated as the control. When a foamy oxydated wastewater appeared such as liming waste it would be a problem and the foam should be removed in such a way that not to be harmfull to the oxidation and other chemical processes. However, anti foam substance must be provided or introduced to clean Technology in the system. The experiment, observation and chemical tests data of this study gives proves the advantages of adding Mn++ in sulphides oxidation system. The catalist adding based on the sulphides content can be considered realistic.
