Biohydrogen production in anaerobic fluidized bed reactors: Effect of support material and hydraulic retention time
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
This study evaluated two different support materials (polystyrene and expanded clay) for biohydrogen production in an anaerobic fluidized bed reactor (AFBR) treating synthetic wastewater containing glucose (4000 mg L(-1)). ...
Performance of the anaerobic co-digestion of pig manure with the inclusion of crude glycerine
(Univ Federal Ceara, Dept Geol, 2016-10-01)
The aim of this study was to evaluate the performance of the anaerobic co-digestion of pig manure associated with increasing doses of crude glycerine, adopting different periods of hydraulic retention time (HRT). A completely ...
Eficiência na remoção de NAT, DBO e DQO utilizando reator aeróbio de leito fluidizado com circulação em tubos concêntricos associado ao decantador de coluna em uma produção intensiva de tilápia
(2016-07-01)
The development of intensive aquaculture is accompanied by an increasing environmental impact produced by the wastewater generated. The recirculating aquaculture systems (RAS) are a compact alternative and manage high ...
Contribute of crude glycerin to increase the efficiency of anaerobic digestion process of dairy cattle manure
(Wiley-Blackwell, 2018-07-01)
The objective of this study was to determine the optimal inclusion doses of crude glycerin in anaerobic co-digestion with dairy cattle manure processed at 10, 17, and 24 days of retention in order to maximize reductions ...
HYPROP measurements of the unsaturated hydraulic properties of a carbonate rock sample
(2020-12-01)
The unsaturated hydraulic properties provide important theoretical and practical information about fluid flow in soils and rocks for a range of soil, environmental and engineering applications. In this study we used the ...
Effect of hydraulic retention time on chemical oxygen demand and total nitrogen removal in intermittently aerated constructed wetlandsRemoção de DQO e Nitrogênio Total em alagados construídos com aeração intermitente em relação ao tempo de detenção hidráulica
(2020-01-01)
This study evaluated the effect of hydraulic retention time on chemical oxygen demand (COD) and total nitrogen (TN) removal in an intermittently aerated constructed wetlands. Two horizontal subsurface-flow constructed ...
BEST-WR: An adapted algorithm for the hydraulic characterization of hydrophilic and water-repellent soils
(2021-12-01)
Water-repellent soils usually experience water flow impedance during the early stage of a wetting process followed by progressive increase of infiltration rate. Current infiltration models are not formulated to describe ...
Performance Evaluation of First-Order Hydraulic Models for COD Removal in Horizontal Subsurface-Flow Constructed Wetlands
(Asce-amer Soc Civil Engineers, 2017-10-01)
The aims of the present study are to verify the performance of four first-order hydraulic models and identify the model that best described the kinetics of the chemical oxygen demand (COD) removal in constructed wetlands. ...
