Pengaruh pH Dan Waktu Pada Pengolahan Limbah Cair Cpo Dengan Proses Ozonasi

Abstract

There have been several methods widely developed for crude palm oil (CPO) extraction from
palm oil fruits, which produces liquid waste around 60% from the total production capacity. This
liquid waste contains organic over than maximum limit, which is permitted by environmental quality
standards of ministerial decision LH No. KEP-51/ MENLH/ 1995. one of the technologies that can
be used is the Ozonation technology. It is done by contacting Palm Oil Mill Effluent (POME) with
ozone. Ozon is produced from  the ozone generator with 18 watt power, with concentration 0,1068
mg/s.  Ozone serves to reduce chemical oxygen demand (COD), oil, and total solid (TTS) in crude
palm oil factory. This research was conducted with variation of PH, 8,10, and 12 with NaOH
addition  and variation of time 10, 20, 30, 40 minutes. The research finding obtained that the
efficiency  chemical oxygen demand (COD) could reach maximum 90 % , with PH 8 in 40 minutes.
