Abstract: Proposed is an electro-coagulation apparatus. The electro-coagulation apparatus includes a reactor having an internal space defined by a top surface, a bottom surface, and a side surface of the reactor; a plurality of electrode plates disposed spaced apart from each other inside the internal space of the reactor, and a pair of first conduits respectively connected to a front end and a rear end of the reactor. Furthermore, a cross-sectional area of the reactor is smaller than a cross-sectional area of each of the first conduits.

Abstract: Proposed is a method of monitoring odor-causing substances in flue gas, which comprises: providing a flue gas containing one or more odor-causing substances; introducing the flue gas into an odor removal unit; producing a gas-phase stream; dissolving a portion of the gas-phase stream in a solvent to produce a liquid-phase stream; and measuring an absorbance of the liquid-phase stream to identify the odor-causing substances.

Abstract: Proposed is a single-atom catalyst (SAC) including a nitrogen-doped carbon structure and a single-atom metal, wherein the single-atom metal forms a coordination bond with a nitrogen atom of the nitrogen-doped carbon structure. When using an electrochemical cell having a pair of electrodes including the single-atom catalyst in an electrochemical advanced oxidation process (EAOP) for water treatment, organic contaminants in wastewater are efficiently degradable under mild pH conditions.
