May 1, 2023 · The main aim of this study was to optimize and maximize the impacts of odor and volatile organic compounds (VOCs) biodegradation in a wastewater treatment plant utilizing a pilot-scale compact trickle bed bioreactor (CTBB).
May 20, 2017 · In general, technologies for odor treatment can be classified into three categories, namely ones employing chemical (thermal oxidation, catalytic oxidation, ozonation), physical (condensation, adsorption, absorption) and biological (using biofilters, biotrickling filters, bioscrubbers and other bioreactor types) treatment (Kennes and
Jul 1, 2021 · As a group of compounds, unpleasant odors are regarded as harmful atmospheric pollutants, which feature low olfactory thresholds but nuisance and adverse health effects [4]. Volatile odors, such as hydrogen sulfide, are corrosion culprits of pipes and other wastewater processing facilities [5]. Therefore, stringent odor-based environmental
Feb 2, 2015 · The BioReactor Composting Technology is a rotating drum that converts dewatered dairy. The rotating drum composting technology–better known as the XACT BioReactor- is ideal for fast composting, ease of operation, and trouble free service. manure into compost. This In tank composting system is designed to successfully process manure by
Feb 5, 2024 · In batch biotransformation experiments, the hybrid bioreactor completely removed 1000 mg L −1 phenol (at this concentration free cells cannot grow) in a hollow-fiber membrane bioreactor containing GAC in 18 h, compared with the 23 h taken in a GAC-free bioreactor.
Feb 1, 2014 · In this work, two conventional biotechnologies (a compost-based biofilter, BF, and a biotrickling filter, BTF), and a hollow-fiber membrane bioreactor (HF-MBR) were comparatively evaluated in terms of odor abatement potential and pressure drop (ΔP) at empty bed residence times (EBRTs) ranging from 4 to 84 s, during the treatment of methyl

May 1, 2010 · Bioreactors play a very important role in the control of VOCs and odorous gases that are emitted by polluting industries. Although a number of different configurations exist, the main types of conventional air phase biological reactors include biofilters, biotrickling filters and bioscrubbers.
Aug 7, 2015 · It is difficult to degrade all contaminants at the same time using one type of microorganism. The combined-bioreactor was developed to cope with gases containing compounds with different water solubility. This bioreactor consists of two reaction zones, one with suspended growth bacteria and another packed with material for attached growth of fungi.
