Abstract
The Sediment Microbial Fuel Cell (SMFC) has been studied in terms of electrical power generation, and water treatment. The study aimed to design and test a Sediment Microbial Fuel Cell (SMFC) and for electrical power generation and water treatment. The sediment has been obtained from Al-Sonobar River bed. It has been characterized to determine the organic matter content and nutrients. The cell has been equipped with a surface aeration system. The electrical current and water pollution indicators have been observed and recorded over time for two-mode aeration systems. Results of the first mode showed that the greatest value for Short Circuit Current (I SC ) was (0.905) mA while the greatest value for Open Circuit Voltage (V OC ) was (0.390) V. While a rise in current and voltage values has been observed in the second mode of aeration, in which the greatest value of Short Circuit Current was (1.240) mA, and the greatest value of Open Circuit Voltage (0.430) V. When the circuit has been connected to an external resistance (R=100) Ω, the values for the current, voltage, current density and power density were (0.805) mA, (0.084) V, (3.18) mA/m 2 , and (0.269) mW/m 2 , respectively. For water analysis, an increase in pH values of (8.90) was observed. The efficiency of removing Chemical Oxygen Demand (COD), phosphates, nitrates and Total Dissolved Solids (TDS) has also increased, reaching: 72.11%, 62.70%, 35.60%, 30.61%, respectively.
