“…Os quais são causadores da abrasão e do cisalhamento da biomassa fixa, e são os principais responsáveis pela manutenção de um biofilme fino e denso no interior do reator. Vários estudos mostram a utilização com sucesso de reatores de leito fluidizado para a oxidação do carbono, nitrificação, desnitrificação e tratamento anaeróbio de uma ampla variedade de águas residuárias (Wolff et al, 1998;Martín et al, 2007;Chen et al, 2008;Kumar & Saravanan, 2009;Beristain-Cardoso et al, 2009).…”

“…Na Europa e EUA, por exemplo, nos anos 90 mais de 65 estações de tratamento já operavam com leito fluidizado em escala real (Lazarova & Manem, 1993) e no Japão, em 2001, foi constatado que cerca de 40 unidades operavam principalmente para tratamento de despejos industriais (Tanaka et al, 2001). Esses reatores têm sido pesquisados também para remoção simultânea de sulfeto e nitrato (Beristain-Cardoso et al, 2008;Beristain-Cardoso et al, 2009), com cargas aplicadas variando entre 0,17 e 0,23 kg NO 3 -N/m 3 .dia, conseguindo completa remoção de N e S e elevada remoção (> 90%) de demanda química de oxigênio (DQO). No Brasil, sua aplicação encontra-se ainda em nível de pesquisas (Distler et al, 1995;Bergamasco et al, 1997;Wolff et al, 1998;Silva et al, 1999;Campos et al, 2002;Martins et al, 2003;Mendonça et al, 2005;Gebara et al, 2006).…”

RESUMONo presente trabalho é apresentada a tecnologia de funcionamento e de concepção do reator de biofilme em leito fluidizado, operando com fluxo contínuo, bem como alguns resultados de pesquisas trabalhando com fluxo intermitente. Embora a tecnologia seja utilizada, mas pouco conhecida no Brasil, os reatores de leito fluidizado já estão consagrados no Mundo. Sendo operadas com menores tempos de detenção hidráulica e altas cargas orgânicas, as instalações são compactas e de fácil inserção no ambiente urbano. A produção de lodo é baixa quando se comparam o reator de leito fluidizado com tecnologias de tratamentos biológicos. Os resultados apresentados para o reator de leito fluidizado mostraram alta eficiência (> 90%) na remoção de matéria carbonácea e nutrientes, quando operado em batelada (RLFB) sob diferentes condições operacionais e de material de suporte (PET e PVC). ABSTRACTThis work presents the operational technology and the conception of the biofilm fluidized-bed reactor with a continuous flow as well as research results with intermittent flow. This technology is used but little known in Brazil despite being already consolidated in the world. Utilizing shorter hydraulic retention times and higher organic loads, the installations are compact and easy to insert in an urban environment. The sludge production of the fluidized-bed reactor is low compared to that of biological treatment technologies. The results from the fluidized-bed reactor demonstrated high removal efficiencies (>90%) for carbonaceous matter and nutrients when operated in the sequencing batch mode (SFBR) under different operational conditions and support materials (PET, PVC).Palavras Chave: biomassa imobilizada; leito fluidizado; reator em bateladas sequenciais; tratamento de efluentes Keywords: fixed biomass, fluidized-bed, sequencing batch reactor, wastewater treatment artigos técnicos http://dx.

“…For instance, Sublette and Woolsey (1988) showed that the H 2 S oxidation by this species was not affected by the presence of glutaraldehyde. Beristain- Cardoso et al (2009a) through a 16S rRNA genebased microbial community analysis have reported that Th. denitrificans was present in the denitrifying biofilm from an inverse fluidized reactor fed with sulfide and organic matter.…”

“…As p-cresol, phenol is another persistent and toxic compound. However, under denitrifying conditions, it was shown to be completely oxidized to CO 2 in the presence of sulfide, while nitrate was totally reduced to molecular nitrogen (Beristain- Cardoso et al 2009a). These results clearly show that the denitrification allows the complete oxidation of p-cresol, phenol and sulfide with a high recovering of nitrate as molecular nitrogen.…”

This review presents progress made over the last decades in the understanding of the metabolic capabilities of nitrifying and denitrifying microorganisms for the biotransformation of nitrogen, sulfur, and carbon compounds present in wastewaters. There are nowadays still many discoveries to be made about the metabolism, phylogeny and ecological behavior of bacteria that play an important role in the nitrogen cycle. The interest of the scientific community in the biological nitrogen cycle is at present very high, because it can be linked to either sulfur or carbon cycles. The connection of biological cycles is of the utmost technological relevance as it has allowed the simultaneous elimination of reduced sulfur and phenolic compounds under nitrifying or denitrifying conditions. The environmental factors affecting the nitrification and denitrification biological processes are described in this review.

“…Among several technologies, the extraction of metal ions using solid materials such as modified silica, alumina [9] [10], activated carbon, and resins has been extensively investigated [11]. These materials have been subjected to functionalization reactions to anchor molecules containing Lewis bases in its structure, which acts as ametal collector [12] [13].…”

Abstract:The main objective of this research is using of Morusnigra leaves powder as adsorptive material for remove of some heavy metals ions, practically Pb(ii), Cu(ii), Mn(ii) and Co(ii). The efficiency of Morusnigra leaves powder was investigated to remove these heavy metals ions form their solutions and wastewater. The parameters such as weight of adsorptive material (g) and Metal ion concentration are investigated in the constant time and pH. The results showed that as weight of adsorptive material increased the removal% was increased. Therefore, the higher removal% for Pb(ii), Cu(ii), Mn(ii) and Co(ii) was found to be 91, 85, 83 and 67 respectively.
