Última Start-up adjustment of a plug-flow digester for cassava wastewater (manipueira) treatment Scientia Agricola Ribas,Maria Magdalena Ferreira; Barana,Ana Cláudia. Manipueira, wastewater of cassava (Manihot esculenta) processing, can be treated by anaerobic biodigestion. To study the start-up process of a plug-flow digester for manipueira treatment, this work consisted of two stages: gradual decrease of the hydraulic retention time (HRT) to the preset time of 4 days or maintaining a fixed HRT of 4 days with gradual increase of the substrate concentration. A digester of 1980 mL capacity was opperated, at constant temperature (32 ± 1º C), with substrate pH corrected between 5.5 and 6.0. The first stage had durations of 16.6; 13.6; 11.6; and 9.6 days and the organic loads were 3.1; 2.0; 2.3; and 2.9 COD L-1 d-1, (chemical oxigen demand) respectively. The second stage was characterized by a fixed HRT (4 days) and organic... Tipo: Info:eu-repo/semantics/article Palavras-chave: Cassava; Anaerobic; Effluent; Biodigestion.

The aim of this work was to investigate the anaerobic biomass formation capable of treating vinasse from the production of sugar cane alcohol, which was evolved within an anaerobic sequencing batch biofilm reactor (ASBBR) as immobilized biomass on cubes of polyurethane foam at the temperature of 55ºC. The reactor was inoculated with mesophilic granular sludge originally treating poultry slaughterhouse wastewater. The evolution of the biofilm in the polyurethane foam matrices was assessed during seven experimental phases which were thus characterized by the changes in the organic matter concentrations as COD (1.0 to 20.0 g/L). Biomass characterization proceeded with the examination of sludge samples under optical and scanning electron microscopy. The...

BABT Ribas,Maria Magdalena Ferreira; Cereda,Marney Pascoli; Villas Bôas,Roberto Lyra. The wastewater of the processing of cassava's flour (manipueira) was submitted to the anaerobic treatment in two phases: acidogenic and methanogenic. In the acidogenic phase, the wastewater was stabilized with NaOH (ASH) and with limestone (ASL). After that, both stabilized effluents were treated by a methanogenic reactor. Then, the effluent of the methanogenic reactor was used as fertilizer on maize in the initial growth stage (30 days), cultivated in pots in a greenhouse. The treatments were T1: control without urea addition (only N from soil); T2: NPK (2.2 g of urea with 45% of N); T3: ASH (84 mL.kg soil-1); T4: ASL (102 mL.kg soil-1); T5: double dose ASH (168 mL.kg soil-1) and T6: double dose ASL (204 mL.kg soil-1). Each treatment was composed by 4... Tipo: Info:eu-repo/semantics/article Palavras-chave: Reuse; Manipueira; Anaerobic digestion; Hydroxide sodium; Dolomitic limestone.
