Abstract
Limbah padat lumpur (LPL) masih menimbulkan
permasalahan tersendiri bagi perusahaan daerah air minum
(PDAM) karena jumlahnya relatif sangat banyak dan belum
termanfaatkan secara maksimal. LPL memiliki kandungan Al2O3
yang cukup besar (18.5%), sehingga sangat berpotensi untuk
dilakukannya recovery aluminium. Pada penelitian ini digunakan
metode acidification untuk me-recovery aluminium karena
metode ini memiliki efisien recovery yang lebih tinggi dan biaya
operasional yang lebih rendah dibandingkan dengan metode lain.
Metodologi dalam penelitian ini menggunakan acidification
dengan pelarut HCl 32% guna mengekstrak aluminium dari LPL
yang diambil dari Sistem Instalasi Pengolahan Air 1 (IPA 1)
PDAM Bandarmasih Banjarmasin KAL-SEL. Tahapan proses
dibagi menjadi beberapa tahap, yaitu tahap preparasi LPL PDAM
Banjarmasin, tahap analisa karakteristik LPL PDAM
Banjarmasin, tahap proses agitated leaching, dan tahap analisa
karakterisasi filtrat hasil proses agitated leaching. Pada penelitian
ini menggunakan serangkaian alat agitated leaching dan beberapa variabel, yaitu konsentrasi pelarut HCl (0.5, 1, 1.5, 2 dan 4 M),
temperatur leaching (30, 50, 70, dan 90 ᵒC), dan waktu leaching
(5, 10, 15, 20, 25 30, 40, 50, dan 60 menit).
Hasil penelitian menunjukkan bahwa hasil optimum dicapai
pada temperatur 90oC dan konsentrasi 2 M dengan recovery
aluminium sebesar 68,49% pada waktu leaching 10 menit. Dari
percobaan didapatkan bahwa semakin tinggi temperatur dan
konsentrasi maka %recovery aluminium akan semakin besar
seiring dengan bertambahnya waktu.
Kesimpulan penelitian ini bahwa LPL PDAM Banjarmasin
memiliki kandungan Al2O3 yang cukup tinggi (18,5%). Dan hasil
optimum yang dicapai adalah pada temperatur leaching 90oC,
konsentrasi 2 M, dan waktu leaching 10 menit.
======================================================================================================
Waste Purification Sludge (WPS) is still pose a problem for
the local water company (PDAM) because of a comparatively
very much and has not been utilized to the fullest. WPS have a
fairly large content of Al2O3 (18.5%), so it has the potential to do
the recovery of aluminum. In this study used acidfication method
for recovery of aluminum because this method has a higher
efficient recovery and lower operating costs compared to other
methods.
The methodology in this research using acidification in the
form of 32% HCl in order to extract aluminum from WPS taken
from Water Treatment Plant System 1 (IPA 1) PDAM
Bandarmasih Banjarmasin KAL-SEL. Stage of the process is
divided into several stages, namely preparation phase of WPS
PDAM Banjarmasin, phase characteristic analysis of WPS
PDAM, phase agitated leaching process, and phase characteristic
analysis of filtrate from agitated leaching process. In this study
uses a series of tools agitated leaching, and several variables,
namely the concentration of HCl solvent (0.5, 1, 1.5, 2 and 4 M), leaching temperature (30, 50, 70, and 90ᵒC), and leaching time (5,
10, 15, 20, 25, 30 , 40, 50, and 60 minutes).
Results from this study showed that the optimum results are
achieved at a temperature 90 °C, and the solvent concentration 2
M with aluminum recovery of 68.49% in the leaching time of 10
minutes. From the experiments it was found that the higher the
temperature and concentration of HCl, the recovery of aluminum
will be even greater with increasing time.
The conclusion of this research that WPS PDAM
Banjarmasin have a fairly high content of Al2O3 (18.5%). And the
optimum results are achieved at a concentration of 2 M, leaching
temperature 90 ° C, and the leaching time of 60 minutes.
