Abstract: Neste trabalho foi mostrada a influência do tipo de material suporte: P4 (plástico reciclado rugoso, diâmetro médio de 2,31 mm, densidade de 900 kg.m-3, superfície específica potencial de 2.596 m².m-3sup) e P5 (polietileno, pouco rugoso, forma cilíndrica, diâmetro médio de 10 mm, densidade de 880 kg.m-3, superfície específica potencial de 3.075m².m-³sup) utilizados em dois reatores biológicos de leito móvel, fluxo contínuo, na remoção de carbono e nitrificação de esgoto sanitário, os quais foram divididos em d… Show more

“…The support medium can be of the most varied materials, among them: gravel, blast furnace slag, wood chips, sand, and corrugated tubes (Sperling, 2013). According to Wolff et al (2010), each support material has different shape, surface area, porosity, roughness, which influences the colonization of microorganisms and the formation of biofilm. With that, the organic matter adhered to the pervious concrete surface can be attributed to its physical characteristics, highlighting its great porosity and high surface area.…”

“…Compared to other reactors, another advantage of the hybrid reactor is the ability to withstand higher organic loads (MORTEZAEI; AMANI; ELYASI, 2018;RAVICHANDRAN;BALAJI, 2019). A combination of these advantages makes the HAR promising for the treatment of industrial wastewater containing high levels of biodegradable organic material (GUPTA; SREEKRISHNAN; SHAIKH, 2018;WOLFF;PAUL;COSTA, 2010). Despite all the registered research, there is still a need to expand investigations into the management of SWW in anaerobic systems, as well as to find new configurations aimed at improving performance, simplifying the various processes, and employing materials that are easy to obtain on the market.…”

“…A great number of support materials have been used to immobilize biomass in aerobic and anaerobic reactors, in order to improve treatment efficiency and the application of economical and viable supports [4][5][6][7][8][9]. The support materials applied to effluent treatment are generally inert, such as sand, gravel, ceramics, plastic rings and sponges.…”

“…A formação de biofilme por organismos autotróficos e heterotróficos pode ocorrer em diferentes materiais como plásticos, metais, vidro, partículas sólidas, madeira entre outros materiais (KOKARE et al, 2009), porém em alguns superfícies este desenvolvimento pode ser favorecido ou não, dependo das características físicas, como rugosidade, porosidade e tamanho dos poros (HUYSMAN et al, 1983;WOLFF et al, 2010), sendo que a extensão da colonização microbiana em uma superfície, pode aumentar proporcionalmente com a rugosidade superficial do material (CHARACKLIS et al, 1990).…”
