Perda de carga em filtros orgânicos utilizados no tratamento de água residuária de suinoculturas

Abstract: Com a realização deste trabalho, objetivou-se parametrizar a equação de evolução da perda de carga, para descrição do processo de filtração de água residuária da suinocultura. No preenchimento das colunas filtrantes, foram utilizados bagaço de cana-de-açúcar triturado, serragem de madeira e pergaminho de grãos de café. Dados de perda de carga em diferentes profundidades e tempos de operação dos filtros orgânicos foram coletados para ajuste das equações de perda de carga. Para as equações ajustadas, foram obtid… Show more

“…Na Figura 1 apresenta-se uma ilustração do filtro confeccionado. Antes da filtração da água residuária, procedeu-se a lavagem do filtro, com a finalidade de eliminar partículas sólidas que pudessem ser liberadas pelo material filtrante e provocar a contaminação do efluente, conforme recomendação de Matos et al (2010).…”

“…This increase in consumption due to lower product price and technological gains (UBA, 2009), generates a large amount of underutilized housing components. The waste and effluents from the production chain of meat and products of poultry, cattle and swine production have high polluting power and if arranged in inadequate methods, generate serious environmental problems that lead to degradation of soil, surface and ground water environments, and health problems and death of living beings, by the presence of pathogenic microorganisms and animals and poisonous insects (ABREU NETO & OLIVEIRA, 2009;SILVA & ROSTON, 2010;OLIVEIRA 2009a and2009b;MATOS et al, 2010;ORRICO JUNIOR et al, 2010a). …”

“…Figure 1 presents an illustration of the filter made. Before filtration of wastewaters, we proceeded to washing the filter in order to remove solid particles that could be released by the filtering material and cause contamination of the effluent, as recommended by MATOS et al (2010). Table 2 shows the values of specific particle mass ( p ρ ), density ( ρ ), porosity (P) and pore volume (PV) of each filtering material evaluated.…”

“…The volume of DCW filtrated in each filter corresponded to five pore volumes and aliquots of 500 ml were collected each time a corresponding pore volume of the filter medium (Table 2) was filtered. The filtration rate during the tests remained above 0.2 L m -2 s -1 , as recommended by Matos et al (2010), since from that point on the sealing of the filter occurs and then it is necessary to change the filtering material. The aliquots collected were stored at 4 °C and sent to the FIOCRUZ laboratory, where the concentrations of TS, TSS and COD were determined, according to the methods presented by APHA (2005).…”
