Performance of and biomass characterisation in a UASB reactor treating domestic waste water at ambient temperature
(South African Water Research Commission, 1998-07)
[Abstract] Domestic waste water from the city of A Coruña (NW Spain) was treated anaerobically in a laboratory-scale upflow anaerobic sludge blanket (UASB) digester, at 20°C, at hydraulic retention times (HRTs) of longer ...
Styrene removal from polluted air in one and two-liquid phase biotrickling filter: Steady and transient-state performance and pressure drop control
(Elsevier, 2011-07)
A Sporothrix variecibatus-inoculated biotrickling filter (BTF) was examined for styrene removal, without and with the addition of silicone oil, at different empty bed residence times. The highest elimination capacities ...
The SHARON process in the treatment of landfill leachate
(IWA Publishing, 2010)
The purpose of this paper was to study the partial nitrification of the nitrogen present in a landfill leachate applying the SHARON process in order to obtain a suitable effluent to the ANAMMOX process. As a first step, ...
Development of a Novel Monolith-Bioreactor for the Treatment of VOC-polluted Air
(Taylor & Francis, 2006)
A novel bioreactor packed with ceramic monolith colonized by a toluene-degrading culture was investigated in order to assess its suitability for waste gas treatment. Operational parameters that were considered included ...
Biodegradation of toluene by the new fungal isolates Paecilomyces variotii and Exophiala oligosperma Biotechnology. 2005;32(1):33-7
(Springer, 2005-02)
Two new fungal strains, namely Paecilomyces variotii and Exophiala oligosperma, were isolated on toluene as the sole carbon and energy source, mineralizing the substrate into carbon dioxide. Fungal strains isolated so far ...
Hydrodynamic behaviour and comparison of technologies for the removal of excess biomass in gas-phase biofilters
(Elsevier, 2004)
The hydrodynamic behaviour of a biofilter fed toluene and packed with an inert carrier was evaluated on start-up and after long-term operation, using both methane and styrene as tracers in Residence Time Distribution ...
Inert filter media for the biofiltration of waste gases – characteristics and biomass control
(Springer, 2002)
Soil biofilters and related systems based onthe use of natural filter beds have been usedfor several years for solving specific airpollution problems. Over the past decade,significant improvements have been brought tothese ...
Removal of formaldehyde, methanol, dimethylether and carbon monoxide from waste gases of synthetic resin-producing industries
(Elsevier, 2008-02)
The removal of mixtures of gas-phase pollutants released from formaldehyde- and formaldehyde resin-producing industries was studied in different bioreactor systems. The waste gases contained formaldehyde, methanol, ...
Biological conversion of carbon monoxide: rich syngas or waste gases to bioethanol
(Wiley-Blackwell, 2011)
Bioconversion of syngas/waste gas components to produce ethanol appears to be a promising alternative compared to the existing chemical techniques. Recently, several laboratory-scale studies have demonstrated the use of ...
Co-digestion of Cheese Whey With Sewage Sludge for Caproic Acid Production: Role of Microbiome and Polyhydroxyalkanoates Potential Production
(Elsevier, 2021-06-08)
[Abstract] The main aim of this work was to evaluate the efficiency of producing caproic acid and other volatile fatty acids using a co-digestion between cheese whey and sewage sludge in a continuous reactor. The effect ...
