Penetapan Kadar Mangan (Mn) dan Seng (Zn) dalam Air Baku dan Air Reservoir dengan Metode Kolorimetri di Instalasi Pengolahan Air (IPA) PDAM Tirtanadi Sunggal.

Abstract

The analysis of manganese (Mn) and zinc (Zn) in water raw and water reservoir in Water Treatment Plant (WTP) PDAM Tirtanadi Sunggal using colorimetric methods. The results of the analysis, the levels of manganese in the raw water is 0,096 mg/l, and in the water reservoir is 0,034 mg/l, with the maximum value allowed for the raw water is 0.1 mg/l and for the water reservoir is 0,4 mg/l, and the analysis results obtained zinc metal content in the raw water is 0,05 mg/l, and in the water reservoir was 0,06 mg/l, with a maximum permissible values for raw water is 0,05 mg/l and for the water reservoir is 3 mg/l. The results of the analysis meets the requirements PERMENKES 492/Menkes/PER/IV/2010 for drinking water (water reservoir) and Government Regulation No.82 of 2001 grade I for raw water .
