FiltrationIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The tanning industry takes the treatment of its liquid wastes very seriously. Wastewater treatment plants have steadily developed since the middle of the 20th Century. The main strategies for treatment fall into three main categories : mechanical, chemical and biological treatment. These are often stitched together to provide an overall strategy. It is fair to say that very loosely, the biological treatment strategies are used for tanneries with access to more land, and chemical treatment strategies are used for tanneries with limited space.

Eaux usées -- EpurationIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In an attempt to find a viable alternative destination for leather buffing waste than landfill researchers at the Cheltech - laboratory, Zaria Nigeria, investigated the adsorption efficiency of activated carbon prepared from leather buffing dust in the treatment of tannery effluent. The optimum pH value at which the effluent was effectively decolourised was establishede to be pH 5.0. At this ph, the minimum carbon dosage and time to effectively remove some heavy metals and decolourise the effluent sample by the activated carbon was determined. The highest percentage decolourisation of the effluent was observed after treatment with 0.6g of activated carbon from leather buffing dust. The minimum period taken to successfully decolourise the effluent was 50 minutes using the determined pH and recorded minimum carbon dosage. Percentage reduction in the concentration of some heavy metals in the effluent was 96,37 %, 28,43 %, 87,87 %, 3,23 % and 0,00 % for chromium lead, iron copper and cadmium, respectively. BOD of the effluent sample was reduced by 84,15 % while COD was reduced by 80,63 %. In comparative terms, the performance of activated carbon from leather buffing waste can be said to compete closely with that of the reference carbon used in this study. It can, therefore, be recommended for treatment of tannery effluent especially where the effluent is being recycled. Note de contenu : - Activated carbon

Oxyde de fer
Peroxyde d'hydrogèneLe peroxyde d'hydrogène (H2O2), communément appelé eau oxygénée ou encore perhydrol (appellation industrielle), est un composé chimique liquide et visqueux, aux puissantes propriétés oxydantes (il est aussi réducteur). C'est donc un agent blanchissant efficace qui sert de désinfectant et (à haute concentration) d'oxydant ou monergol dans les fusées spatiales.

UltrasonsIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Successful decolorisation of real textile wastewater was achieved by means of the advanced Fenton process in conjunction with ultrasound technology. A synergy factor of 6.9 for this combined method was determined. The decolorisation followed zero-order kinetics, and the rate increased with increasing zero-valent iron dose and decreasing pH and hydrogen peroxide concentration. The optimum conditions for an American Dye Manufacturers Institute decolorisation value of 1638 ADMI was found to be a pH of 3.0, an ultrasound frequency of 47 kHz, a zero-valent iron dose of 1.0 g l?1, and a hydrogen peroxide concentration of 1.03 × 10?2 m. Under these conditions, the estimated operating cost to decolorise 96% true colour was estimated to be $US 4.51 m?3. The study demonstrated that the given combined method could be applied to decolorise textile wastewaters.

PhytoépurationLa phytoépuration est au sens large l'épuration par les plantes. Celles-ci peuvent contribuer à épurer ou dépolluer les trois grands milieux que sont l'air, les sols et l'eau. Il s'agit d'un système de traitement des eaux utilisant des plantes (généralement plantes macrophytes), des substrats et des microorganismes au sein d'une zone humide artificielle (ou "constructed wetlands" pour les anglophones). Les systèmes de phytoépuration peuvent être composés d'un ou plusieurs filtres plantés.Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Enhanced Root-zone systems offer the first serious alternative to the conventional biological of tannery effluents. With capital and running costs a fraction of the demanding activated sludge process, the simplicity and elegance of this technology has been demonstrated in both equatorial and temperate regions. With performance and area needs in line with yesterday's intrusive technology, these robust green systems offer a real alternative. There are also other industrial opportunities.

- Fig. 6 : High salinity resistance. Typical selection from 300 plants subjected to increasing levels of salinity as mg/l. Reeds are healthy at far higher salinity values than typical of tannery effluents.
