پیل سوختی میکروبی(mfc) شکل جدیدی از انرژی تجدید پذیر است.دراین پیل ها مواد آلی به عنوان سوخت مصرف می شوند وباازتجزیه مواد آلی توسط باکتریها انرژی الکتریکی تولید می شود.فاضلاب وپساب نیز می توانند به عنوان سوخت درپیل مصرف شوند وضمن تولید انرژی الکتریکی پساب نیز تصفیه می شود. در این تحقیق روند تولید انرژی وتصفیه شدن پساب با بررسی جریان،مقاومت ، ولتاژ پیل وآنالیز cod,tds,ec الکترولیت بررسی می شود. ...

Recently developed man-made structures have caused environmental pollutions, and unfortunately, in spite of the deteriorating affairs and repeated warnings by scientists and experts, the degree of contamination is increasing considerably. One of the natural sources undergoing changes is the coasts. It is mainly due to human activities which have led to a change in the quality and quantity of se...

Bio-electrical responses obtained from freshwater sediments by employing microbial fuel cell (MFC) technology were investigated in this experimental study. During the electricity generation, organic matter in the sediment was microbially oxidized under anaerobic conditions with an electrode serving as a terminal electron acceptor. It was found that the sediment organic matter (SOM) associated w...

To investigate the removal effect of pollutants in mariculture sediment by microbial fuel cell (SMFC) and its power generation capacity, effects external resistance, cathode pH dissolved oxygen concentration (DO) on SMFC system were investigated. The results showed that optimal parameters for as follows: resistance = 1500 Ω, 8.5 DO 5 mg·L -1 . In these situations, performance organic degradatio...

Current reliance on fossil fuels is unsustainable due to pollution and finite supplies. Microbial cell factories serve as promising alternatives renewable energy resources. Microorganisms generate electricity in their metabolism; act as catalysts for converting the chemical energy into electricity. In Microbial Fuel Cell (MFC), electrons provided by microorganisms flow through an electrical ext...

INTRODUCTION Plant microbial fuel cells (P-MFCs), and more general sediment microbial fuel cells, make use of electricigenic metabolism of microorganisms in anoxic soils and sediments. Electricigenic microorganisms are able to respire organic carbon from the soil or sediment with an electrode as final electron acceptor [1]. In this work, the focus is on the anode buried in the sediment, the ele...
