STUDI BANDING TEKNOLOGI PENGOLAHAN LIMBAH CAIR PABRIK KELAPA SAWIT

Abstract

In the last ten years Indonesia has already developed more than 15 Crude
Palm Oil Factories (CPOF). Unfortunately the major of them do not have proper
wastewater treatment plants (WWTP) yet. General speaking that in Indonesia the
palm area has been increasing rapidly. Because of the very large palm area, almost
all CPOF use a large area for the WWTP and the main processes of WWTP are
anaerobic and aerobic system using large ponds as lagoons. The most environmental
problems appear such as the bad quality of the effluent from WWTP and in
maintaining units of the WWTP. The aim of this assessment is to compare the
WWTP belong to 3 CPOF (PT. Kertajaya, PTP Nusantara IV Bah Jambi and PT.
Smart Tbk) and RANUT as a research product from Palm Research Center located
in Medan. Wastewater (produced by CPOF) used for Land application is also
discussed and it is well known in using the wastewater to fertilize the palm plantation.
A recommendation for the wastewater treatment system has been proposed. The
system has eight processes including oil separation or first sedimentation,
neutralization, equalization, anaerobic degradation, aerobic degradation, final
sedimentation and sludge drying.
