EFEKTIVITAS PENGGUNAAN METODE GABUNGAN METODE BIOFILTER ANAEROB DAN FITOREMEDIASI DALAM MENURUNKAN KADAR BOD, COD DAN TSS PADA LIMBAH CAIR DOMESTIK

Abstract

The increasing population is one of the impacts of population density is the increasing need for drinking water, which also impacts increasing the amount of wastewater released. One approach that can be used in domestic wastewater management is using anaerobic biofilter and phytoremediation technology methods to reduce pollution levels. This study aimed to determine the effectiveness of anaerobic biofilter and phytoremediation in reducing BOD, COD, and TSS levels in domestic wastewater at Perum Sumput Asri, Driyorejo District, Gresik Regency. This study uses variations of Biofilter media, namely in reactor one using ginger coral media and in the second reactor using bioring media for phytoremediation plants using water hyacinth plants. The retention time is 12 hours in each basin with a discharge of 3.6 l / hour with a continuous upflow system. The results of research from biofilter and phytoremediation media variations are very good coral ginger and water hyacinth biofilter media which have the effectiveness of reducing BOD levels by an average of 53%, COD levels by an average of 51.39% and TSS levels by an average of 72.40%.
