Summary:A system and method of using a biofilter for removal of heavy metals. A biofilter apparatus for extracting heavy metals from wastewater using Spirulina microalgae is disclosed. The biofilter apparatus comprises a column having a column cap and a base, an inlet hose connected to the column cap, an outlet hose connected to the base, a plurality of holder disks connected to the base, a microfilter found between the holder disks, and a plurality of microbeads contained in the column. The microbeads are coated with a microalgae wherein the microalgae purifies the wastewater that flows through the inlet hose and produces cleaner wastewater that exits through the outlet hose. The microfilter filters out heavy metal (e.g., mercury, cadmium, lead, copper, and zinc) from the wastewater to form biomass briquettes. A plurality of biofilter apparatus may be connected in series to create a biofilter system.
