TEKNOLOGI ULTRAFILTRASI UNTUK PENGOLAHAN AIR TERPRODUKSI (PRODUCED WATER)
ABSTRACT: Produced water
generated from crude oil exploitation contains compounds such as BTEX, ammonia,
phenol, and mercury that are dangerous for human health and environment. Some
technologies have been applied for produced water treatment such as biological
wastewater treatment with microorganism, coagulation and flocculation. In this
research, produced water was treated using ultrafiltration membrane.
Specifically this research is aimed to obtain characteristic of produced water
and ultrafiltration membrane (functional groups in membrane), to determine the
membrane performance (flux and rejection) and the effect of ultrafiltration on
the final characteristic of produced water. Characterization of produced water
showed that the COD, TOC, toluene, and xylene content exceed the minimum values
of wastewater quality standards for oil, gas, and geothermal activities.
Membrane analysis using SEM showed the polyethersulfone membrane having an
asymetric membrane structure. FTIR analysis showed there were aromatic
components of SO2, PVP, and OH stretching group in the membrane. In variation
of pressure, the permeate flux of PES decrease 2,5% for 1 bar, and 59% for 2
bar. In addition, PES can reject 96,8% COD, 99,9% TOC, 83% toluene, and 94,6%
xylene. This research demonstrated that ultrafiltration was capable for
produced water treatment since the effluent can meet the government quality
standards of water disposal for COD and TOC contents
