KEBERADAAN ANILIN DI SUNGAI CITARUM HULU AKIBAT PENGGUNAAN AZO DYES PADA INDUSTRI TEKSTIL
Abstract: The dyeing and
printing processes in textile industry produces wastewater containing residual
dyes. The most widely used textile dyes are azo dyes. The textile industry is
one of the main industries in West Java province, where one of the textile
industry centers is Majalaya textile industry center. Majalaya textile industry
center had begun since the 1910s, where in Majalaya subdistrict located the
most textile companies which produced textile wastewater. Textile wastewater
which contained azo dyes discharged into the Citarum Hulu River directly or
after treatment in the Waste Water Treatment Plant (WWTP) owned by the company.
One of the product metabolites produced from azo dyes biodegradation by
bacteria in anaerobic conditions are various anilines. Several anilines which
are persistent, could flow to downstream of Citarum Hulu River. Various
anilines, referred to as total anilines, could be analyzed by the colorimetric
method using visual spectrophotometer. Total anilines in water samples after
biodegradation by anaerobic bacteria was 14.46 mg/l highest. While total
aniline in river water samples was 3.58 mg/l highest. And at the downstream of
Citarum Hulu River, there was total of aniline 1,825 mg/l highest in the river
sediment samples. DO in the river water samples were 4.25 - 7.8 mg/l, while pH
of the river water samples were 7.1 - 10.7. The occurence of total aniline in
textile wastewater and river water samples in Citarum Hulu River (Majalaya
subdistrict) and in river sediments at the downstream of Citarum Hulu indicated
biodegradation of azo dyes from textile wastewater by anaerobic bacteria.
