Usate of Filter Tube to Reduce Pb, Turbidity And Increase pH of Rain Water Flowing Through Zinc Rooftop House
Abstract: Pb contained in rain
water comes from zinc rooftop, beside that, it comes from the pollutant
dissolved and comes into rain water reservoir and is used for community
drinking water source. This research objective is to evaluate Pb, pH and
turbidity of rain water before and after process and to analyze efectivity of
shell sand filtration and activated carbon absorbtion in the filter tube to
decrease Pb and turbidity and increase pH of rain water. This research is an
experiment with pre and post test design with control and observational with
cross sectional design. It is conducted in Pontianak and Kubu Raya West
Kalimantan in 2016 with two target regions which represent urban and rural
ones. The result indicated that average lead (Pb) contained in rain water and
turbidity process is high with 131.7 g/l and 20 NTU and pH is low with 5.2.
After process, Pb become 0.71 g/l and turbidity become 5.66 NTU while pH
increases to 6.9. The effectivity of filter tube to reduce lead (Pb) contained
in rain water is 99.4% and to reduce turbidity is 72%.
