Fluid dynamic analysis is an important branch of several chemical engineering related areas, such as drying processes and chemical reactors. However, aspects concerning fluid dynamics in wastewater treatment bioreactors ...

In arid and semiarid ecosystems, primary productivity and nutrient cycling are directly related to the amount and seasonal distribution of precipitation. However, depending on morphological, phenological, physiological, ...

The removal of biological nitrogen from a synthetic wastewater with different ammonium nitrogen concentrations (50 and 100 mgN-NH4+/L) by a nitrification and denitrification process using a sequencing batch biofilm reactor ...

The anaerobic biological treatment of pentachlorophenol (PCP) and methanol as the main carbon source was investigated in a horizontal-flow anaerobic immobilized biomass (HAIB) reactor at 30 +/- 1 degrees C, during a 220-day ...

Four anaerobic fluidized bed reactors filled with activated carbon (R1), expanded clay (R2), glass beads (R3) and sand (R4) were tested for anaerobic degradation of LAS. All reactors were inoculated with sludge from a UASB ...

This study aimed to evaluate the carbon emissions and immobilization balance of the productive process of planted forests in the north of Minas Gerais State, Brazil, having been the data collected in Eucalyptus planting ...

As endoglicanases EC 3.2.1.4 são enzimas capazes de hidrolisar as ligações glicosídicas ?-1,4 da celulose, resultando na liberação de glicose, celobiose e celo-oligossacarídeos. Empregadas mundialmente em diversos processos ...

The characteristics of material directly affect the reactor efficiency, because the number and the types of cells what adhere in each material support can be totally different from material to another. From the development ...
