PENGARUH METODE KOAGULASI, SEDIMENTASI DAN VARIASI FILTRASI TERHADAP PENURUNAN KADAR TSS, COD DAN WARNA PADA LIMBAH CAIR BATIK
Abstract: Batik industry
in Indonesia increased,
so that the
impact result from the production process
in the form
of wastewater is
increasing. Wastewater disposal
after staining and washing process
without processing will
improve environmental contamination such as TSS, COD and color levels.
The problems of batik wastewater contamination can be resolved by treatment of
wastewater in chemistry and physics. One way batik wastewater treatment are
coagulation, sedimentation and filtration. Filtration media are used as filter
media is activated charcoal, quartz sand and zeolite. The purpose of
this research to
determine the effect
of coagulation, sedimentation
and filtration variation method to decreased levels of TSS, COD and
color in the wastewater of batik. The type of this research was a true
experiment with pre-test post-test group design. Samples
of this research
were batik wastewater
with levels of
TSS, COD and color
are 818 mg/
l, 1133,57 mg/
l and 100
TCU. Data analyzed using one-way
ANOVA. The result after
treatment of coagulation,
sedimentation and filtration
variety occurs decreased levels
of TSS, COD
and color on
filtration variation of
activated charcoal and quartz
sand, respectively for
99,8%, 99,49% and
99,6%, variation of the
zeolite filtration and activated charcoal was, 99,6%, 92,31% and 99,5%, and variations in zeolite filtration and quartz
sand was 99,7%, 89,92% and 99,3%. Based on the statistical test using ANOVA
test on the TSS levels were obtained p= 0,190, while the COD were obtained
value of p= 0,008 and the value of color was p= 0,017. The methods of
coagulation, sedimentation and filtration variation using activated charcoal,
quartz sand and zeolite can reduce TSS, COD and color levels. There is no difference between the variation of filtration to decrease levels
of TSS, while there is a difference between the variation filtration to
decreased levels of effluent COD and color Batik.
