Tannery industry

Lipids have been studied more intensively for appHcations in tanneries. Industrial Upases can be used for degreasing (80).

Rautenbach and MeUis [75] describe a process in which a UF-membrane fermentor and a subsequent NF-treatment of the UF-permeate are integrated. The retentate of the NF-step is recycled to the feed of the UF-membrane reactor (Fig. 13.8). This process has been commercialised by Wehrle-Werk AG as the Biomembrat -plus system [76] and is well suited for the treatment of effluents with recalcitrant components. The process also allows for an additional treatment process, like adsorption or chemical oxidation of the NF-retentate, before returning the NF-retentate to the feed of the UF-membrane fermentor. Usually, the efficiency of these treatment processes is increased as the NF-retentate contains higher concentrations of these components. Pilot tests with landfiU leachates [75] and wastewater from cotton textile and tannery industry have been reported [77]. An overview of chemical oxygen demand (COD) reduction and COD concentrations in the permeate are shown in... 

Benzene (BS) and naphthalene sulfonates (NPS) are commonly used in the textile industry as dye bath auxiliaries and in the tannery industry as dispersants and wetting agents. After application, these compounds are discharged into surface waters and their presence in industrial effluents was not reported due to the lack of an appropriate analytical technique. Recently, ion-pair chromatography-ESI-MS and LC-ESI-MS was developed to determine BS and NPS with the final goal of determining polar, ionic, and water-soluble pollutants in wastewater [7],... 

The ELM pertraction technology has good potential for more applications at industrial scale in the near future. The industries in question might include metal mining and refinery operations (precious metals and platinum group metals are good examples), tannery industry (recovery of hexavalent chromium), and processing of nuclear wastes (recovery of uranium, strontium, and other metals).
