Abstract

The purpose of this review is to provide current information regarding industrial wastewater treatment with MFC technology with the addition of biocatalysts and pretreatments. Moreover, this review also updates industrial waste treatment technology with MFC technology in Indonesia. Waste could be generated from domestic activities as well as non-domestic activities, such as industries. Industries produce waste with quite high organic content. This organic material is not easily degraded in biological treatment. Wastewater treatment, currently, aims only to meet standards quality and not to reuse. In Indonesia, the reuse processes, one of which is still rarely found in the form of energy. Industries that can process and convert wastewater energy can help the government realize sustainable development in the energy sector. One of the technologies is the Microbial Fuel Cell (MFC). Previous MFC research that had been carried out was limited to laboratory scale with a volume of less than 1 L and, among them, used mixed or artificial waste. MFC processing uses anode in wastewater as a substrate source and generates electrons under anaerobic conditions. Electron formation could be accelerated by adding biocatalysts such as enzymes and specific microorganisms. The processing occurred in an anaerobic anode that could be increased by increasing the substrate's biodegradability value in the waste. The biodegradability value can be increased by pretreatment with ozone or ultrasonic technology. In Indonesia, research on industrial wastewater treatment with MFC as well as biocatalyst and pretreatment is still relatively minimal.

Abstract

To investigate its ability, graphite material was characterized by X-Ray diffraction (XRD), Fourier Transform Infrared Spectrophotometer (FTIR), Thermo Gravimetry Differential Thermal Analyse (TG-DTA), and Brunauer Emmet Teller (BET). Adsorption capability was evaluated by using Congo Red dye and Direct Orange dye solutions. The experiment was studied by using kinetic, isotherm, and thermodynamic parameters. The result of XRD characterization showed that graphite has four characteristic peaks which are 26,405?(002), 44,50?(101), 54,45?(004), and 77,32?(006). FT-IR characterization showed that the vibration at 3402 cm-1, 1635 cm-1, and 1381 cm-1. TG-DTA analysis showed that graphite has only one decomposition peak at 760 oC. BET analysis showed that the surface area of graphite was 11,558 m2/g. The optimum pH of CR and DO dyes were in pH 6 and pH 2 with contact time of 120 minutes.  Kinetic adsorption model of CR and DO dye onto graphite follow pseudo-second-order model with a liner regression coefficient close to one. Isotherm parameter of CR and DO adsorption onto graphite follow Langmuir isotherm model with spontaneous endothermic process. The desorption process of graphite was used HCl to remove the dyes.  Regeneration process of graphite showed that the capacity of adsorption decreased after it was reused 3 times.
