Analisis Kadar Kebutuhan Oksigen Kimiawi (KOK), Kebutuhan Oksigen Biologi dan Minyak/Lemak pada Limbah Cair Pabrik Kelapa Sawit.

Abstract

Analyses have been performed to determine the level of Chemical Oxygen Demand and Biological Oxygen Demand by titration method, Oil / Fat with gravimetric extraction-method on Liquid Fluid of Palm Oil Factory. By heating for 2 hours at temperature 150oC done at COD Destruction Block then dititrasi obtained COD A plant amounting to 96,384 mg / L, factory B as much 144,576 mg / L, factory C as much 160,64 mg / L, by incubation and then titrated Obtained A plant BOD content of 0.4 mg / L with dilution 500 times, factory B of C as much as 0.4 mg / L with dilution 1000 times, by drying, extracting and weighing obtained Oil / A plant oil content of 19 mg / L, plant B as much as 14 mg / L, factory C as much as 71 mg / L. From the above results, COD, BOD and Oil / Fat content of factory A and B meet the quality standard, while the C plant content of COD and BOD meet the quality standard, but the oil / fat content does not meet the quality standard set by Permen / LH / 5/2014 On Wastewater Quality Standards.
