Pengolahan Limbah Cair Sasirangan Menggunakan Filter Arang Aktif Cangkang Kelapa Sawit Berlapiskan Kitosan Setelah Koagulasi dengan FeSO4
Abstract: Filtration of
sasirangan wastewater using oil palm shell active charcoal coated with chitosan
after coagulation with FeSO4 had been done. One of the aims of this research is
to compare the value of pH, COD, Turbidity, TSS, total chromium and total lead
in sasirangan wastewater after the treatment standards for waste quality set by
Peraturan Gubernur Kalimantan Selatan Nomor 036 Tahun 2008, and to determine
adsorption ability of filter based on the volume of Pb(II) solution being flown
to 50 grams of adsorben. The wastewater of sasirangan was processed by using
FeSO4 as coagulant under the optimum conditions at pH 8-10 and concentration
750 mg/l followed by filtration. Parameters of effluent being measured were pH,
COD, Turbidity, TSS, total chromium and total lead. Determination of adsorption
capacity of the filter was done by flowing 35 liters of Pb(II) solution into
the filter. The results showed that FeSO4 as coagulant has reduced pH value
from 8,73-7,95 while the percentage of decrease for COD, TSS, turbidity and
total lead were 93,33%, 56,95%, 65,10% and 10% respectively. After sasirangan
wastewater was filtered, TSS, turbidity and total lead decreased as much as
77,25%, 87,63% and 77,78%. As much as 50 grams oil palm shell active charcoal
coated with chitosan reach its saturation after being passed by 30 liters of
Pb(II) solution.
