This study found that a bioflocculant produced by Bacillus subtils is able to treat leather wastewater, but the flocculation activity of the bioflocculant needs to be improved. In this paper, the culture conditions of Bacillus subtilis were optimised by single-factor and orthogonal tests. The results showed that the bioflocculant produced by Bacillus subtilis through optimising the culture conditions had good flocculation efficiency. The optimal culture temperature after optimisation was 36°C, the inoculum dose was 5% (v/v), at pH7.5, the culture time was 48 hours, the flocculation efficiency increased from 46.12% to 73.71%, an increase of 59.82%, and the production of flocculant increased from 0.45g/L to 0.61g/L, an increase of 35.56%. Through optimising the culture conditiops of Bacillus subtilis the flocculation efficiency of the bioflocculant, was improved and both the cost of flocculation and secondary pollution were reduced.

Hydroxydes doubles lamellairesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Layered double hydroxides (LDHs) and mixed oxides derived from its calcination have been reported in the literature as promising adsorbent materials in the remediation of several environmental pollutants. Due to their physicochemical properties, adsorption capacity and simple thermal regeneration procedure, these materials are interesting alternatives to conventional adsorbents. In this context, this study presents the synthesis, characterization and the results obtained with calcined LDH of CuZnAI for the colour removal in water of Acid Red 357, an anionic dye used in leather dyeing. The solid was synthesised by the co-precipitation method and characterised by N2 physisorption, Xray diffractometry and Fourier transform infrared spectroscopy. The influence of contact time on the adsorption process, adsorbent dosage and the memory effect of the mixed oxide were evaluated. The results showed an 80% removal percentage for counting times over 90 minutes and the ability of the adsorbent to reconstruct the lamellar structure after adsorption.

Solutions aqueuses (chimie)Index. décimale : 667.3 Teinture et impression des tissus Résumé : Effluent generated by the textile industry can be highly coloured. Before the waste is disposed into receiving waters, colour removal is an important consideration. Because of their complex molecular structures, dyes present in the textile wastewater are not removed easily by conventional wastewater treatment processes. They are fairly stable to light, as well as heat, and resist biodegradation, thus posing a challenge to conventional physico-chemical and biological treatment methods. Although adsorption technology using activated carbon has been considered to be an effective and proven technology, it has its limitations as it is expensive and necessitates regeneration. As cost is an important consideration in most developing countries, efforts have been made to explore the possibility of using various low-cost alternatives that are biodegradable, abundant, readily available, and are derived from waste materials. This article is a compilation of the investigations carried out by numerous researchers (from 2002 onwards) on the effective use of different kinds of low-cost adsorbents for the removal of specific dyes from textile wastewater.

LaccasesLes laccases (EC 1.10.3.2) appartiennent à une famille d'enzymes ayant pour cofacteur du cuivre. C'est une oxydase (oxydoréductase, EC 1) que l'on retrouve dans de nombreuses plantes, champignons et micro-organismes.
Le cuivre est lié sur plusieurs sites de la protéine. On distingue trois types. Les types 2 et 3 sont appelés grappe tri-nucléaire. Le cuivre du type 1 est soluble dans l'eau. Le mercure déplace le cobalt complexé dans les laccases. Les complexants du cuivre peuvent le déplacer et le remplacer par du cobalt. Les cyanures complexent également le cuivre, mais dans ce cas il n'est pas possible de réinsérer du cobalt.
Les laccases oxydent les dérivés phénoliques mais d'une façon ménagée qui transforme la lignine en monolignol.
SurfactantsIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Laccase (benzenediol, oxidoreducase; Enzyme Commission Number) is a multi-copper oxidase from biomass. Laccase enzyme recycling on molecular oxygen as an electron acceptor can be applied for the decolorisation of synthetic dyes. The decolorisation of 49 commercial reactive dyes using laccase was investigated. The effects of diverse structure surfactants on decolorisation are discussed. The absorption spectra of reactive dyes after a laccase biodegradable reaction were analysed. Reactive dyes based on anthraquinone and azo structures could be decolorised using the enzyme and their chemical structures broken. Reactive dyes based on an anthraquinone structure were easier to decolorise than those based on an azo structure. Surfactants could affect the decolorisation of dyes with an enzyme. The effect of nonionic surfactant on the decolorisation of anthraquinone dyes was the reverse. The cationic surfactant could improve the decolorisation rate of diazo dye. The effect of the anionic surfactant on dye decolorisation was small. Most commercial reactive dyes could be decolorised and biodegraded using a laccase enzyme under mild conditions. Laccase enzyme biotechnology has potential applications in the decolorisation of reactive dye wastewater.
