PENURUNAN KADAR COD DAN TSS PADA LIMBAH INDUSTRI PEMBUATAN TEMPE DENGAN TEKNOLOGI BIOFILM MENGGUNAKAN MEDIA BIOFILTER KOMBINASI BIOBALL DAN LIMBAH KULIT KERANG

Along with the increasing population growth also resulted in an increasing in the amount of waste generated. One of the pollutants contained in tempe industry wastewater are COD and TSS. This paper describes the pilot plan study of tempe industry wastewater treatment using anaerobic and aerobic submerged biofilter using bioball and clamshell waste media. In this study, anaerob-aerob reactors were used with the continuous system and varying the time detention in the reactor. The detention time used were 8, 13,5 and 27 hours. From the results of research conducted, showed that the reduction in COD and TSS concentrations reach 52% and 46% for COD and TSS. With values for COD reduction from 10.730,97 mg / l to 5182,58  mg / l and for TSS, from 880 mg / l to 472 mg / l.
