The present invention provides a bioelectrochemical system for removing a polyvalent ion present in seawater etc., capable of producing electricity. The bioelectrochemical system according to the present invention comprises: an anode chamber comprising an anode which accommodates an electron produced when treating an organic material in wastewater with a microorganism; a cathode chamber comprising a cathode receiving the electron from the anode, for producing a hydroxide ion by reacting the electron with oxygen and water provided from the outside, and depositing the polyvalent ion inside an electrolyte by using the hydroxide ion; and an anion exchange membrane for blocking the polyvalent ion inside the electrolyte from moving to the anode chamber. Also, the present invention provides the bioelectrochemical system capable of removing the polyvalent ion present in seawater etc., and simultaneously producing hydrogen. The present invention comprises: the anode chamber, provided with the anode to which electrochemically active bacteria are attached, for producing the electron by having organic wastewater, as a substrate, injected thereto; the cathode chamber, provided with the cathode, for removing the polyvalent ion and simultaneously producing a hydrogen gas by having seawater, as an electrolyte, injected thereto; the anion exchange membrane for separating the anode chamber and the cathode chamber and preventing the polyvalent cation in seawater from moving to the anode chamber; and a power source connected between the anode and the cathode.

The object of this invention is to provide a method of producing a bio-diesel oil in a great amount in a relatively short time, in which oil/fat and alcohol, used as reactants, are homogeneously mixed with each other to form a single liquid phase mixture which effectively react with each other. The method includes transesterifying the oil/fat and alcohol in the presence of alkyl ester. Additionally, in the method, alkyl ester is added to a mixture of the oil/fat and alcohol by recycling alkyl ester as a product to the mixture. Furthermore, the method includes (a) an acidic catalyst, and (b) transesterifying the pre-esterified oil/fat with alcohol in the presence of alkyl ester.
