pHIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Conventional methods for chromium removal from industrial effluents may be limited by technological or economical constraints, especially when they are applied to dilute metal solutions. Thus, biotechnological processes, which are efficient at low metal concentrations and require the use of fewer chemicals, may play an important role. The chromium recovery proposed here is based on the specific uptake of this metal by acidophilic fungi. Fifty acidophilic fungal isolates from the Río Tinto basin, an extreme acidic environment, were tested. Most of them were resistant to Cr(III) and Cr(VI) solutions at concentrations up to 10 mmol/L. The influence of different experimental conditions was evaluated (medium concentration, kinetics, requirement of induction etc.). Fungal isolate 143 was able to remove 63% of Cr(III) at 0.1 mmol/L, 74% at 1 mmol/L and 21% at 10 mmol/L. These are the best Cr(III)-fungal-uptake results at acidic pH described in the literature so far. It should be possible to use these acidophilic fungi, for example in tannery wastewater, as they can resist chromium concentrations and pH values found in these effluents (between 6.5-7.5 mmol/L Cr (III) and pH as low as 3-4).

Membrane liquide en émulsionIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : This article illustrates an experiment with the removal and recycling of Cr (VI) in a wastewater by the technique using an emulsion liquid membrane. The membrane solvent, the carriers and the types and amounts of stabiliser have been optimised. The liquid membrane recipe in optimal form is prepared as an emulsion to treat the water sample containing Cr (VI) so as to determine the effects of operating conditions, such as the pH of the internal and external water phase, the amount of carrier, the speed and the time of preparing the membrane, the membrane internal ratio and the emulsion water ratio.

PigmentsIndex. décimale : 667.2 Colorants et pigments Résumé : Contaminants such as dyes unproperly discharged in the environment are a big problem to overcome. Some technologies have been developed and applied for dye-wastewater treatment before its disposal in the waterbodies. Among them, adsorption is highlighted and a plenty of adsorbents are proposed in the literature.

Tannage -- DéchetsIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : As a highly complex aqueous effluent, tannery wastewater from leather industry should be treated appropriately before discharging into the environment. Membrane technology has been shown to be a promising approach for tannery wastewater treatment as it may achieve “Zero Liquid Discharge (ZLD)”. This work, as the state-of-the-art, attempts to review the world-wide research trends of membrane technologies, the technical recapitulation and recent advances of such technology for tannery wastewater treatment. Generally, manufacture membrane, membrane-based integrated process, MBR, NF, UF and RO are the hotspots in this field. Details of different membrane technologies configured for tannery wastewater treatment, such as membrane materials, scale, membrane modules, operating conditions and removal efficiency of pollutants, are also summarized. It should be noted that membrane fouling is still a major challenge in the membrane technology during tannery wastewater treatment. Therefore, process coupling, either within diverse membrane technologies or between membrane and non-membrane technologies, is considered as a promising alternative to treat the leather tannery.

The pilot plant comprised two connected parts: an aerobic tank filled with carriers and a submerged membrane tank. The MBBR-MBR system reduced the hydraulic retention time to 1 day, which is very promising compared with conventional biological treatment in the textile industry. The removal efficiency of chemical oxygen demand reached 93%, which is almost the maximum for a biological process treating this type of wastewater, as well as the colour removal performance, which achieved 85%. Additionally, 99% of total suspended solids were removed due to filtration. Furthermore, new dyeing processes reusing the treated water were performed. The quality of the new dyed fabrics with treated water was compared with reference fabrics. Colour differences between new dyed fabrics and reference fabrics were found to be within the general requirement of the textile industry (ΔECMC(2:1) < 1). The reuse of treated water in new dyeing processes is beneficial both for the industry and for the environment, because the textile sector is an intensive water consumer during both the dyeing and finishing processes.
