| dc.description.abstract | The water treatment plant in the Hamparan Perak by use Belawan river. The
Belawan river water used as samples is raw water and then to processed of
reservoir water in the water treatment plant Hamparan Perak. Analysis of iron
(Fe) and manganese (Mn) were performed using an UV-Visible
spectrophotometer. Analyzes were performed on february 11th 2016 and
February 19th 2016. The analysis results on the February 11th 2016 acquired the
iron (Fe) content of the raw water is 0,29 mg/l and for the water reservoir is 0,03
mg/l. The manganese (Mn) content of the raw water is 0,09 mg/l and for the
water reservoir is 0,062 mg/l. The analysis results on the February 19th 2016
acquired the iron (Fe) content of the raw water is 0,29 mg/l and for the water
reservoir is 0,02 mg/l. The manganese (Mn) content of the raw water is 0,08
mg/l and for the water reservoir is 0,002 mg/l. This indicates that the water
treatment that has been done in PDAM Hamparan Perak according to standards. | en_US |
