Sarwoko Mangkoedihardjo : Review on BOD, COD and BOD/COD ratio: A Triangle Zone for Toxic, Biodegradable and Stable Levels
Prof. Dr. Ir. Sarwoko Mangkoedihardjo MScES
This paper reviewed research works on biodegradability of organic matter containing materilas, attempting
to provide a tool for treatment and monitoring strategies. Organic matter parameters were simplified as BOD,
COD and BOD/COD ratio. Treatment methods were classified into natural, physical, chemical, biological, phytotechnological
and combined treatment. For various operating conditions, it was formulated the zonation of the
BOD/COD ratio and characterized by the limits of toxic, biodegradable and acceptable or stable zones.
