Variasi Penambahan Media Adsorpsi Kontak Aerasi Sistem Nampan Bersusun (Tray Aerator) Terhadap Kadar Besi (Fe) Air Tanah Dangkal di Kabupaten Rembang
Abstract: People in the
Jatihadi village are using dug wells water which contain high iron level. The
average of iron level is 2.79 mg/l. Appropriate technology tray aerator with
media contacts zeolite and activated carbon is the right solution to overcome
the problems of high Fe content. This study aims to analyze the difference
variation the addition of contact media adsorption on tray aerator for dug
wells iron level in Jatihadi village, Sumber subdistrict, Rembang regency.
Method: The design of this study is pre experiment research with one group
pretest posttest design. We used
Inductively Coupled Plasma (ICP) method to measure the iron level. Water sample
volume for each aeration is 20 liters and there are 16 repetitions. The media
that we used in this research is zeolite and activated carbon. Results: The
result showed the average levels of iron before treatment is 2.79 mg/l, and
after the first treatment down to 0.21 mg/l, after second treatment is 0.25
mg/l. Statistical analysis showed that there is no difference between variation
of contact media adsorption for dug wells
iron level, but Wilcoxon analysis showed that there is a significant
difference between before and after treatment for adding zeolite or activated
carbon. Conclusion: The efficiency of tray aerator with the addition of zeolite
is higher than addition of activated carbon.
