1. Silicon carbide hollow fiber membranes developed for the textile industry wastewater treatment
Abstract In order to reduce the impacts of the industrial effluent on the environment, silicon carbide hollow fiber membranes were prepared by the precipitation-immersion technique and sintered at 1450 and 1500 °C. The membranes were characterized by X-ray diffraction, their surface structure was characterized by scanning electron microscopy and atomic forc

2. Degradation of textile dyes by cyanobacteria
Abstract Dyes are recalcitrant compounds that resist conventional biological treatments. The degradation of three textile dyes (Indigo, RBBR and Sulphur Black), and the dye-containing liquid effluent and solid waste from the Municipal Treatment Station, Americana, São Paulo, Brazil, by the cyanobacteria Anabaena flos-aquae UTCC64, Phormidium autumnale UTEX1

3. A study on the functional properties of silk and polyester / lyocell mixed fabric
ABSTRACT Silk is one of the valuable fibers in textile industry. It is used for delicate applications in many areas such as sarees, suitings, curtains and luxurious interiors. To diversify the properties and usages silk is mixed with polyester and lyocell. The fabric is dyed with natural dyes (kum kum, indigo, barberry) as well as synthetic dyes (reactive dy

4. Additive effects of CuSO4 and aromatic compounds on laccase production by Pleurotus sajor-caju PS-2001 using sucrose as a carbon source
Laccase enzymes are now commercially available, and a laccase/mediator combination is currently marketed for indigo dye bleaching in textile manufacturing; replacing traditional chemical-based processes with enzymatic technology reduces the need for effluent treatment. However, an inexpensive source of these enzymes will be needed to enable wider application

5. Decolorization of textile dyes by cyanobacteria
Cianobactérias estão amplamente distribuídas no ambiente e podem ser uma alternativa eficaz e econômica para a remoção de corantes de efluentes de indústrias têxteis. O presente trabalho investigou o potencial de seis linhagens de cianobactérias de descolorir onze tipos de corantes têxteis. A absorção máxima de cada corante foi verificada usando

6. Aplicação da água residuária das salinas no tratamento de efluente têxtil
O tratamento de efluentes coloridos e alcalinos tem sido um desafio para as indústrias têxteis. Uma alternativa para a remoção de cor destes efluentes é a aplicação do cloreto magnésio como coagulante. O íon magnésio, em pH elevado, se hidrolisa, formando o hidróxido de magnésio que possui larga área adsortiva e cargas eletrostáticas positivas

7. Caracterização do efluente líquido no processo de beneficiamento do índigo têxtil
The great diversity of the textile industries activities causes the formation of wastewaters with high complex characteristics during the productive process, according to the industrial process used. The principal aim of the present work is the characterization of the wastewater from the textile industry that process the indigo, located in the Industrial Dis

8. Biodegradação e toxicidade de corantes têxteis e efluentes da Estação de Tratamento de Águas Residuárias de Americana, SP / Biodegradation and toxicity of textile dyes and wastes from a Municipal Treatment Station, Americana, SP.
As indústrias têxteis da região de Americana geram grande quantidade de efluentes e resíduos sólidos com grande carga de corantes que são naturalmente de difícil degradação. Assim o objetivo do presente trabalho foi avaliar a possibilidade de biodegradação dos corantes têxteis RBBR, índigo e preto enxofre, e dos resíduos resultantes da Estaçã

9. Aplicação da tecnologia de eletrofloculação na recuperação do corante índigo blue a partir de efluentes industriais
The indigo blue dye is widely used in the textile industry. When discarded, besides polluting the environment, it affects the appearance and transparency of aquatic bodies, causing damage to flora and fauna. The removal of this dye from industrial effluents is difficult due to its resistance towards degradation. This work proposes the recovery of indigo blue

10. Biodegradação de efluente têxtil por Pleurotus sajor-caju
Effluents generated by the textile industry are of environmental concern because of the presence of dyes with complex molecular structure, which confer them recalcitrant characteristics. Indigo is one of the most widely used dyes within the textile sector and studies have suggested that edible fungi may be capable of its biodegradation. A textile effluent wa
