Functioning of biofilter
After fabrication, the effluent water is let into the filter system. The level of water is maintained above the biomedia in the filter system. The air tubes are then connected with the aeration. Now the effluent water is allowed to flow through the biomedia and the filtered water reaches the false bottom from where the water is lifted by air diffusion. The biomedia of filter provides substrate for growing of bacteria. The biological filter cycle is continous under aerated condition. |
