Pengaruh Campuran Kapur, Tawas Dan Feri Klorida Dengan Dosis Yang Berbeda Untuk Meningkatkan Kualitas Air Gambut
ABSTRACT
Peat water generally has an acidic pH, brownish-red color, and high
turbidity. To improve the quality of peat water, coagulation-flocculation
processing can be carried out. The types of coagulants used are lime, alum, and
ferric chloride. This study aims to determine the effect of a mixture of lime, alum,
and ferric chloride at different doses on improving the quality of peat water.
Water samples were taken from Kualu Nenas Village, Tambang District, Kampar
Regency, and Riau. This study used an experimental method with a completely
randomized design. There were 4 treatments and 3 replications. Each treatment
has a water volume of 1 liter with a settling time of 20 minutes. The data obtained
were analyzed using Analysis of Variance (ANOVA). If there is a real effect, then
the Duncan's Multiple Range Test (DMRT) level of 5% is carried out. The
treatments applied were, P1 (0.50 g lime + 0.41 g alum + 0.45 g ferric chloride),
P2 (0.50 g lime + 0.476 g alum + 0.336 g ferric chloride), P3 (0.50 g ferric
chloride). g lime + 0.544 g alum + 0.224 g ferric chloride, P4 (0.50 g lime + 0.612
g alum + 0.112 g ferric chloride). Based on the results obtained, it can be
concluded that a mixture of lime, alum, and ferric chloride can improve the
quality of peat water The best treatment was found in P1 0.50 g lime + 0.41 g
alum + 0.45 g ferric chloride with pH measurements of 7.6, turbidity 2.28 NTU,
color 44.7 Pt / Co and organic matter 49, 3 mg / L.
