Filtration is a process for separating the contaminants from wastewater by passing through the porous media. Multimedia filter refers to a filter which utilizes three or more different media as opposed to a sand filter that typically uses one grade of sand alone as the filtration media. Experimental study was carried out to upgrade the conventional treatment process by introduction of multiple media. A laboratory scale multimedia filter model consisting of three reactors placed in series was developed for treatment of domestic wastewater. All three reactors were packed with different combinations of packing media such as plastic scrubbers, brick bats and aerocon stones of varying sizes. The model was operated for varying detention time. The results obtained from this experimental study showed removal efficiency for BOD as 70%, COD as 62% and TS as 87% for 24 hours of detention time
