Associated ecological, environmental, and high risk: Ozone: Mainly expands the sludge flocs by reducing the zeta potential value, surface hydrophobicity of floc increases-
2022/1/1/ · Bioreactors for SmF have a different mode of operation depending upon product targeted which in turn includes metabolites and biomass. Based on the operation, bioreactors are classified as the batch, continuous, and fed-batch reactors. The agitation creates tumbling in the solid matrix by reducing the heat generated. Agitation is a
2016/8/11/ · Abstract. The content of this chapter focuses on the anaerobic BioReactor Landfill (BRL), an alternative to the traditional “dry tomb” landfill, with the aim of a more rapid degradation of the organic fraction of Municipal Solid Waste (MSW) through leachate recirculation. This technology is mainly based on the moisture increase of waste
2020/1/1/ · 10.1. Introduction. A bioreactor is a vessel-like device that provides a uniform background for microorganisms to grow and maintains an uninterrupted balance in the biochemical reactions carried out by these microorganisms to produce desired metabolites [1].The applications of bioreactors may be extended for biomass production
2022/6/25/ · Its main goal is to keep liquids out of a traditional sanitary landfill. A bioreactor landfill, however, is an innovative municipal solid waste landfill (MSWLF) recently developed, evaluated, and promoted by the US Environmental Protection Agency (USEPA). In a bioreactor landfill, liquids are added to help microorganisms break down the solid
2022/3/18/ · Bubble column photobioreactors with diameters of 7–24 cm are illuminated by fluorescent tubes [83, 95, 102] or LED lamps [84, 85, 96].Light sources are distributed around the cylindrical bioreactor to achieve a homogenous illumination [83, 93,94,95].The incident light intensity decreases from the surface to the middle of the cylindrical bubble
2007/1/1/ · The main objective of bioreactor selection, design, and control is to provide the optimal environment for a biological reaction system. The bioreactor should provide optimum conditions (e.g., temperature, pH, oxygen transfer, mixing, and substrate concentration), in addition to its basic function of containment.
2016/1/15/ · Biological treatment using sulfate-reducing bacteria (SRB) is a promising approach to re-mediate acid rock drainage (ARD). Our purpose was to assess the performance of a sequential system
2023/4/19/ · To reduce shear forces, slow-speed stirring bioreactors have been developed by introducing thin silicone tubing hanging inside the periphery of bioreactors (Hvoslef-Eide et al., 2005) and somatic embryos of carrot, Norway spruce, birch, and cyclamen have been cultured. However, none of these modifications have resulted in
2017/4/1/ · Membrane bioreactor (MBR) technology is considered a well-established, mature technology with many full-scale plants around the world treating municipal and industrial wastewater. Design and process optimization has helped to reduce the capital and operating expenses of MBR plants. The current growth of the MBR market is
2022/8/9/ · The application of the bioreactor can greatly reduce cell damage, thus affecting the cells’ physiological activity, and finally improve the maximum cell growth density (Nascu et al., 2021). East China University of Science and Technology, Tongji University, and the University of Surrey proposed to use high-dimensional model representation
2023/1/1/ · In this context, a bioreactor represents a closed system, a culture vessel (i.e., tank, bottle, chamber, etc.) with a medium inlet for nutrient supply and optionally a medium outlet for waste removal. During bioreactor development, there is already a high tendency toward up-scalability to be considered for effective mass production.
2002/1/1/ · This paper presents the advantages of sulfate-reducing bioreactors in treating mine drainage, including: the ability to work in cold, high altitude environments, handle high flow rates of mildly
