EFEKTIVITAS PEMBUBUHAN KAPORIT DALAM MENURUNKAN KADAR ZAT BESI (Fe) PADA AIR SUMUR GALI TAHUN 2013
Abstrak: Ground water often
contains iron (Fe) is quite large. That it contains iron (Fe) in the wa-ter can
cause the color of the water turns yellow brown after a while contact with air.
At-tempts to obtain water with iron levels are eligible, do not always have the
sophisticated technology but could also be using chemicals like the simplest
way and do not require great effort and cost in use, one of which is by way of
affixing chlorine.
This study aims to determine how much chlorine affixing effectiveness in
lowering levels of iron (Fe) in the dug well water. This type of research is
the design of Quasi-Experiments (Quasi-Experiment Design) using a time series
design (Time Series Design), which uses la-boratory tests. Samples taken as
much as 28 liters of water in which the sample for the pre-test while the other
sample is done by providing chlorine treatment at a dose of 1.5 mg / l, 2.0 mg
/ l, and 2.5 mg / l with a settling time of 30 minutes, 60 minutes and 90
minutes.
The results showed that iron (Fe) in water wells dug by the settling time
30 minutes look after affixing chlorine with a dose of 1.5 mg / l decrease of
16.66%, a dose of 2.5 mg / l of 22.6% , 2.5 mg / l at 28.37%. Later in the
deposition time of 60 minutes after affixing chlo-rine with a dose of 1.5 mg /
l decrease of 24.75%, a dose of 2.0 mg / l at 34.15%, and at a dose of 2.5 mg /
l down 45, 70%. While at the time of deposition 90 minutes after affixing
chlorine with a dose of 1.5 mg / l decrease of 37.12%, a dose of 2.0 mg / l at
49.00%, and a dose of 2.5 mg / l decrease by 50 , 16%%.
To address water quality dug well that levels of substance iron (Fe) is
more than the standard, it can be used chlorine as a water treatment dug wells
to get clean water that meets health requirements. It is advisable for people
to use a dose of 2.5 mg / l after 90 minutes set-tling time. To study further examination
of other chemical parameters such as organic com-pounds that can be known
whether the chlorine also can decrease these parameters.
