【 摘 要 】

Biofilter is a wastewater treatment system implemented by flowing waste water into a biological reactor filled with filter media to reproduce contaminant decomposing microorganisms contained in wastewater using aeration or without aeration. This study aims to determine the appropriate combination to reduce the heavy metal content of mercury (Hg). This study used an experimental method with a completely randomized design consisting of five treatments and four replications. The treatment given was the difference in the weight composition of Gracilaria sp. and Anadara granosa for combination. In this study, the number of heavy composition is: treatment P0 (100% Gracilaria sp.), P1 (75% Gracilaria sp. 25% Anadara granosa), P2 (50% Gracilaria sp., 50% Anadara granosa), P3 (25% Gracilaria sp., 75% Anadara granosa) and P4 (100% Anadara granosa). The parameters observed in this study were levels of Mercury heavy metal in seaweed, shellfish and water. Data analysis was carried out using Variant Analysis (ANOVA) and continued with Duncan's Multiple Distance Test. The results show that the use of a combination of Gracilaria sp. and Anadara granosa can absorb Hg heavy metal in water that has been given 1ppm mercury and get the most optimum results in P2 with a composition of 50% Seaweed (Gracilaria sp.), 50% Blood Shellfish (Anadara granosa) and Zeolite.
