Optimisation of biogas production from anaerobic digestion of agro-industrial waste streams in Brazil

Marc Árpád Boncz; L. P. Bezerra; Carlos Nobuyoshi Ide; Paula Loureiro Paulo

The important Brazilian agro-industry produces significant amounts of wastewater with high concentrations of biodegradable compounds. A lot can be gained if wastewater treatment would take place using anaerobic reactors instead of the anaerobic lagoons generally used now. Apart from preventing methane emissions to the atmosphere this would permit the use of the biogas as a source of energy. To facilitate implementation of this technology also in small and intermediate sized companies a system requiring only minimal maintenance is needed. The need for maintenance by skilled labour can be reduced using an automated process control system, which is being developed. Cassava (manioc, tapioca) processing wastewater has been treated in a lab scale UASB reactor equipped with an on-line monitoring system, to test a control strategy based mainly on pH control. Good results have been obtained treating not only pre-acidified but also treating raw (diluted) cassava processing wastewater.

Diurnal variation in planktonic crustacean population densities in a marginal lake of the Brazilian Pantanal

William Marcos da Silva; Kennedy Francis Roche; Carlos Nobuyoshi Ide

Studies on the zooplankton of marginal lakes in Brazíl, especially in the centre-west region that includes the Pantanal wetland, consist primarily of taxonomic inventories; ecological estimates of abundance have generally considered each system as a whole (NEvEs et al. 2003 and references therein). Information on horizontal and vertical distributions of zooplankton, including diurnal and seasonal changes, and their potential food items (phytoplankton) and potential predators (invertebrates, fish) within any particular lake is lacking. Such information is important when considering interactions between species (PERTICARRARI et ai. 2004, PELICICE et ai. 2005, lGLESIAS et al. 2007). W e analyzed the vertical distribution of the crustacean zooplankton during a 12-hour period in the open water of a shallow marginallake in the Pantanal wetland.

Effects of scale and Froude number on the hydraulics of waste stabilization ponds

This paper presents the findings from a series of computational fluid dynamics simulations to estimate the effect of scale and Froude number on hydraulic performance and effluent pollutant fraction of scaled waste stabilization ponds designed using Froude similarity. Prior to its application, the model was verified by comparing the computational and experimental results of a model scaled pond, showing good agreement and confirming that the model accurately reproduces the hydrodynamics and tracer transport processes. Our results showed that the scale and the interaction between scale and Froude number has an effect on the hydraulics of ponds. At 1:5 scale, the increase of scale increased short-circuiting and decreased mixing. Furthermore, at 1:10 scale, the increase of scale decreased the effluent pollutant fraction. Since the Reynolds effect cannot be ignored, a ratio of Reynolds and Froude numbers was suggested to predict the effluent pollutant fraction for flows with different Reynolds numbers.
