PERBANDINGAN LIMBAH DAN LUMPUR AKTIF TERHADAP PENGARUH SISTEM AERASI PADA PENGOLAHAN LIMBAH CPO

Liquid waste crude palm oil derived from strilizer unit, clarification unit and exiles from hydrocyclone. Liquid waste from crude palm oil industry such as34.20% extractwithoutN(chemical composition) and13.19% Glutamitacid(amino acidcomposition)might potentially contaminate ground water and water bodies. This studyaimed todetermine the effect of aeration systemonCPOandwasteactivated sludge in theaerationbasinin order to get the concentrationdecreasedBOD5, CODandpH of theeffluentanddetermine variations inthe ratio betweentheCPOwasteactivated sludgetooptimize theconcentrationimpairmentBOD5, CODandeffluentpH.In this study, liquid wasteandsludgeCPOinserted into thebioreactorwith avolumeratiovariation.Then eachaeratedbioreactorsusingaeratorsandaerationsystemswas observedtodecrease invalue ofBOD5, COD, andpHby usingactivated sludge.
