29. BactÃrias com Potencial BiotecnolÃgico na DescoloraÃÃo de Corantes TÃxteis / Bacteria with biotechnological potential in the discoloration of textile dyes
The discharge of effluents from textile industries for water bodies is currently a major concern for environmentalists as a function of synthetic dyes used to color fabrics thus polluting the environment. Biological treatments, especially with the use of bacteria, present themselves as the most economically viable and widely used to decolorize colored efflue

30. Avaliação da efetividade de remoção de cor de soluções corantes e efluentes têxteis pelo tratamento fotocatalítico de óxidos de ferro recobertos com dióxido de titânio
This work evaluated the use of ferrites encapsuled with titanium dioxide (CoFe2O4@TiO2) for photocatalytic removal of color of dye (Methylene Blue and HRFL Drimaren Blue) solutions and textile effluents. The CoFe2O4@TiO2 and TiO2 used in the tests was synthesized according to the polymeric precursors method, and the solids obtained were characterized by X ra

31. UTILIZAÇÃO DE HUMINA COMO UM MATERIAL ALTERNATIVO NA ADSORÇÃO/DESSORÇÃO DE CORANTES REATIVOS / HUMIN USE AS AN ALTERNATIVE MATERIAL IN ADSORPTION / DESORPTION OF REACTIVE DYES
Environmental problems have become increasingly acute and frequent in recent decades, mainly due to unrestrained population growth and increased industrial activity. The textile industry merits especial attention in this context, since large volumes of water are used in finishing processes, which results in substantial quantities of liquid effluent. The obje

32. Diagnóstico ecotoxicológico dos efluentes lançados no complexo estuarino do Jundiaí/Potengi, Natal/RN
Untreated effluents that reach surface water affect the aquatic life and humans. This study aimed to evaluate the wastewaters toxicity (municipal, industrial and shrimp pond effluents) released in the Estuarine Complex of Jundiaí- Potengi, Natal/RN, through chronic quantitative e qualitative toxicity tests using the test organism Mysidopsis Juniae, CRUSTACE

33. Study of the potential of using waste effluent from the distillation of the leaf oil of eucalyptus (Corymbia citriodora (Hook) Pryor and Johnson 1976), as a natural dyestuff for dyeing cotton fabrics / Estudo do potencial de uso do resíduo efluente gerado da destilação do óleo de folhas de eucalipto (Corymbia citriodora (Hook) Pryor e Johnson 1976), como corante natural para o tingimento têxtil de algodão
Atualmente, os corantes naturais vêm ganhando maior interesse da sociedade, fazendo crescer um novo nicho de mercado, que valoriza produtos obtidos de matériasprimas naturais, devido aos menores danos causados à saúde humana e ao meio ambiente. Uma fonte potencial para obtenção de corantes encontra-se na operação industrial da obtenção de óleo ess

34. Electroflocculation for textile wastewater treatment
This work reports on the viability of the electroflocculation (EF) process for chemical oxygen demand (COD), turbidity and color removal from a raw effluent originated from a particular textile industry related to hemp manufacture. Firstly, the following operational parameters were optimized: current density; initial pH; electrolysis time; material of the el

35. Avaliação da biodegradabilidade de efluentes têxteis do beneficiamento secundário de malhas de poliéster tratados com Reagente de Fenton
From the environmental point of view, the textile sector is outstanding for the generation of large amounts of biorecalcitrant effluents. In this paper the textile effluent biodegradability, both before and after its treatment with Fenton's Reagent, were compared by means of biologic tests. These tests showed that the Fenton treatment lowered the biodegradab

36. Remoção de corantes em efluentes têxteis utilizando espumas de poliuretano e resíduos de sementes de Mabea fistulifera Mart. / Dye removal in textile effluents using polyurethane foams and residues of Mabea fistulifera Mart.
The absorption is successfully used in removing the organic contaminants found in textile effluent. This work proposes the use of alternative absorbents to remove the direct dyes (Direct Red 80) and reactive (Reactive Blue 21) in aqueous solutions and in effluent samples. Two absorbents were tested: the synthetic polyurethane foams (EPUs) and the seed residu
