Analisis Pengaruh Penambahan Lumpur Gambut Terhadap Penurunan Kekeruhan, Zat Organik Dan Warna Air Gambut Dengan Cara Koagulasi Menggunakan Koagulan Aluminium Sulfate (Al2(So4)3)
Peat water is a surface water that’s found in swamp and lowland areas that
have characteristics of organic matter, turbidity and high color. One of peat water
treatment that can be used by coagulation-flocculation. This study aims to
determine the effect of peat sludge addition in coagulation-flocculation process
with Coagulant Aluminium Sulfate (Al2(SO4)3) 1%. Peat water was taken in
Rimbo Panjang Village, Tambang District, Kampar Regency, Riau Province. Peat
sludge used in this study amounted to 6.7 gr/L, 13.4 gr/L, 20 gr/L, 26.7 gr/L and
33.4 gr/L. Rapid stirring that used 250 rpm during 1 minute and slow stirring at 60
rpm, 40 rpm and 20 rpm every 20 minutes. The results of this researchshowed that
the value of turbidity increased by 18.52% with allowance efficiency from
70.70% to 89.22%, organic substance efficiency increased by 3.97% with
efficiency from 96.03% to 99.82% and color efficiency parameters increased by
1.08% with efficiency from 98.73% to 99.81%.
