Abstract: A Multi-Stage Wastewater Treatment and Hydroponic Farming Device comprises a compact basin, a moving bed biofilm reactor (MBBR), a modified wetland material, at least one microbial fuel cell (MFC) and a distributor. The MBBR and modified wetland material are disposed within the basin. Openings in the distributor retain hydroponic plants. In one example, wastewater enters through the MBBR which performs primary treatment of wastewater. Treated wastewater is further treated by modified wetland material and the MFC which generates electrical energy that supplies other components. Treated wastewater is pumped through the distributor and processed by hydroponic plants which extract growth inducing nutrients from the treated wastewater. Resultant water treated by the device is selectively recycled through various parts of the device or extracted from the device and used for other purposes.
