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

Reactive Black 5 (RB5) is one of the dyes used in textile industries in Indonesia. However, the high color content can interfere with the condition of water bodies if not treated. This waste treatment process is usually treated with biological treatment processes. Biological processing often used is the MBBR unit and activated sludge. This study aims to determine the RB5 dye’s bio-sorption efficiency using MBBR processing and activated sludge. MBBR processing and activated sludge consist of seeding, acclimatization, and running stages. This research was carried out using a real textile wastewater approach by adding 100 mg/L RB5 and adding 1000 mg/L starch solution. The processing results of the seeding stage indicate increasing in biomass. The acclimatization stage with 50% and 75% of wastewater indicates increased biomass and color removal. The RB5 color removal efficiency results in the MBBR unit and activated sludge show 41% and 84% values. The MBBR processing shows fluctuations each time where the desorption process occurs in the color removal. For this reason, the ozone pre-treatment process is conducted in the MBBR unit. The integrated pre-treatment with MBBR results show the same fluctuation as the previous processing with a color removal efficiency of 43% with a color removal efficiency of 43%.
