Kombinasi Bahan Koagulan Moringa Oleifera Dan Eichornia Crassipes Untuk Mereduksi BOD Dan COD Dalam Air Limbah Domestik

Abstract

Diversified processing natural coagulant material into something that can provide the benefits that broader and a greater contribution towards the community.This research aims to review a combination of coagulant effective in reducing, bod cod in the water. domestic wasteThe research is experimental laboratory committed in the lab traya tirta makassar.This research was preceded by the moringa oleifera are and eichornia Journal of Chemical Process Engineering e-ISSN Number 2655 2967 32 crassipes, the manufacture of coagulant, from both of them and then take waste water after that prepare for the, stirrer both of coagulant included in a beaker glass then solution stirred with a jar, test after what filtrat and precipitate separated with paper filter ( filter membrane ) ago came the measurement of BOD and COD. The results of research is the value of BOD highest on the treatment eichornia crassipes reaching 47,651 %, moringa, oleifera are followed as well as combination 1 berturut-turut decline is found in a combination 2, a combination 5, a combination 3 and combination 6.As well as to the COD that is shows that kind of treatment since eichornia crassipes experienced declines in the highest of 64,181 % then moringa oleifera are, a combination 1 and combination 2, as well as berturut-turut decline is found in a combination 5 and 3.The conclusion of the combination of moringa oleifera are and eichornia crassipes the best reduce BOD and COD which is a combination 1 ( comparison 10: 10 ).
