Pré-filtração em pedregulho e filtração lenta com areia, manta não tecida e carvão ativado para polimento de efluentes domésticos tratados em leitos cultivados

Abstract: RESUMO:O presente trabalho teve como objetivo comparar sistemas de filtragem, composto de pré-filtro de pedregulho seguido de filtro lento com o meio filtrante areia e no topo manta sintética não tecida e pré-filtro de pedregulho seguido de filtro lento com meio filtrante areia e carvão ativado granular e no topo manta sintética não tecida, para polimento de efluentes domésticos tratados em leitos cultivados, visando à aplicação na fertirrigação. Na comparação dos sistemas de filtragem, avaliou-se a eficiência… Show more

“…Paterniani et al (2011) in a comparative study on different filtration systems, evaluated the efficiency in the removal of suspended solids and the results indicated that the introduction of a layer of activated carbon and the use of a synthetic blanket in the sand filter, provided greater efficiency in the with similar values (27.2 and 34.2 %) with those found in the crafts filters of this research (Figure 2). Carmo et al (2012) also showed that the highest average filtering efficiencies were for sand-based sand filters when compared to the disc filter.…”

“…Among the many studies (Crozariollo Neto et al, 2011;Paterniani et al, 2011;Carmo et al, 2012;Miranda et al, 2012;Silva et al, 2012;Ribeiro & Paterniani, 2013;Oliveira et al, 2016) in the development of alternative filters emphasize the importance of good results for irrigation, due to its low cost and easy acquisition of the filtering material, being able to be incorporated within the agriculture irrigated by the small farmer and allowing to attend small projects of localized irrigation, providing quality water and favoring optimal operation throughout the irrigation system.…”

“…Derivado do carvão vegetal, o carvão ativado com alta porosidade e superfície específica, em combinação com areia é empregado na despoluição de gases tóxicos e purificação de água por adsorção de toxinas (SASAKI, LIMA, QUINÁIA, 2014;PATERNIANI et al, 2011). O material pode ainda ser usado para fins medicinais e farmacêuticos.…”

“…In the experimental analysis of the disc filter processes, Oliveira (2005) found that the use of small localized irrigation is growing in Brazil owing to the scantiness of water resources and the need to save water during the irrigation process. These factors trigger the development of materials and equipments that improve on small irrigation systems (PATERNIANI et al, 2011).…”
