A comprehensive review on application of bioreactor for industrial wastewater treatment

Abstract

In the recent past, wastewater treatment processes perform a pivotal role in accordance to maintain the sustainable environment and health of mankind at a proper hygiene level. It has proven as indispensable by government regulations throughout the world due to the importance of preserving freshwater bodies. Human activities, predominantly from industrial sectors, generate an immeasurable amount of industrial wastewater loaded with toxic chemicals, which not only cause dreadful environmental problems but also leave harmful impacts on public health. Hence, industrial wastewater effluent must be treated before releasing into the environment to restrain the problems related to industrial wastewater discharge to the environment. Nowadays, biological wastewater treatment methods have been considered as an excellent approach for industrial wastewater treatment process because of their cost-effectiveness in the treatment, high efficiency, and their potential to counteract the drawbacks of conventional wastewater treatment methods. Recently, the treatment of industrial effluent through bioreactor has proven as one of the best methods from the presently available methods. Reactors are the principle part of any biotechnology-based method for microbial or enzymatic biodegradation, biotransformation, and bioremediation. This review aims to explore and compile the assessment of the most appropriate reactors, like, packed bed reactor, membrane bioreactor, rotating biological contactor, up-flow anaerobic sludge blanket reactor, photobioreactor, biological fluidized bed reactor, continuous stirred tank bioreactor, etc. that are extensively used for distinct industrial wastewater treatment.

Biochemical Characteristics of Laccases and their Practical Application in the Removal of Xenobiotics from Waters

“…There are two groups of bioreactors: (i) enzyme bioreactors (EBR) and (ii) enzyme membrane reactors (EMR) [311]. In membrane bioreactors, enzyme molecules can be immobilized in or on the membrane primarily by covalent bonds to prevent elution and loss of the catalytic properties of the enzyme during successive reaction cycles.…”

Tratamiento Anaerobio Y Valorización Energética De Las Aguas Residuales Del Proceso De Nixtamalización Del Maíz: Una Revisión

“…Por otra parte, Buitimae-Cantúa et al (2020) reportan una generación de nejayote de 50 millones de m 3 /año. Este tipo de agua residual es producida en micro y pequeñas industrias e incluso en producción convencional rural, en donde existe una disposición final inadecuada, es decir, se descarga directamente al drenaje y en los casos rurales en la superficie de suelo, derivando impactos ambientales en los ecosistemas, cambios en la composición del suelo, contaminación en los mantos freáticos y en algunos casos la muerte de organismos acuáticos y terrestres (Chai et al, 2021;Meena et al, 2021;Ribas-Agustín et al, 2017).…”

Microbial Electrochemical Systems and Membrane Bioreactor Technology for Wastewater Treatment

“…A membrane bioreactor (MBR) is a well-known technology with high solid-liquid separation efficiency for the treatment of industrial or domestic wastewater. It provides high effluent quality [5], high organic load [6,7], low sludge yield [8,9], improved nitrification removal performance [10,11], and perfect separation of hydraulic retention time (HRT) and solids retention time (SRT) [12,13]. In general, an MBR separates particles and pathogenic bacteria, e.g., E. coli, through a membrane with a pore size of 0.01-1 mm.…”
