1. Consortium of Microalgae for Tannery Effluent Treatment
Abstract Wastewater generated in tanneries have essential elements for microalgae growth, but it has also some toxic compounds that may hinder or restrain the growth of microalgae in this environment. This work tested microalgae consortium growth originating from a deactivated effluent treatment decanter of a complete tannery (beamhouse to finished leather)

2. Biossorção de íons Cr(III) de soluções aquosas sintéticas e efluente de curtume utilizando a macrófita aquática Pistia stratiotes
RESUMO O cromo é um metal tóxico amplamente utilizado em processos industriais, por isso a constante preocupação com os efluentes líquidos gerados. Uma vez lançados sem o devido tratamento podem comprometer a qualidade do corpo receptor. Este trabalho teve por objetivo analisar o processo de biossorção na remoção de íons Cr(III) de soluções aquo

3. Optimization studies on production of a salt-tolerant protease from Pseudomonas aeruginosa strain BC1 and its application on tannery saline wastewater treatment
Treatment and safe disposal of tannery saline wastewater, a primary effluent stream that is generated by soaking salt-laden hides and skin is one of the major problems faced by the leather manufacturing industries. Conventional treatment methods like solar evaporation ponds and land composting are not eco-friendly as they deteriorate the ground water quality

4. Concomitant production of protease and lipase by Bacillus licheniformis VSG1: production, purification and characterization
This study was aimed at producing protease and lipase simultaneously on a common medium by Bacillus licheniformis VSG1, which was isolated from a tannery effluent. The effect of media composition with respect to protein source, lipid source and emulsifier on the production of protease and lipase was analysed. Both those enzymes were produced under optimized

5. APLICAÇÃO DE PROCESSOS OXIDATIVOS AVANÇADOS HOMOGÊNEOS E HETEROGÊNEOS NA DEGRADAÇÃO DE EFLUENTES DE CURTUME
This study investigated the application of advanced oxidative processes for the homogeneous and heterogeneous degradation of a tanning effluent. The catalytic activity of a solid oxide containing manganese was evaluated in the heterogeneous systems. The experiments were performed in a photocatalytic batch reactor in laboratory scale. The solid used was the c

6. Application of electroflocculation technique for the tannery effluent treatment / AplicaÃÃo da tÃcnica de eletro-floculaÃÃo no tratamento de efluentes de curtume
In the present work has been studied the electro-flocculation efficiency on the reduction of organic and inorganic material concentrations such as Chemical Oxygen Demand (COD), turbidity, total solids and metal, mainly chromium, on an untreated tannery effluent using a pair of electrodes. For this purpose, a lab scale Electro-Flocculation (EF) reactor was co

7. Genotoxicity and mutagenicity of water contaminated with tannery effluents, as evaluated by the micronucleus test and comet assay using the fish Oreochromis niloticus and chromosome aberrations in onion root-tips
Cytotoxicity of metals is important because some metals are potential mutagens able to induce tumors in humans and experimental animals. Chromium can damage DNA in several ways, including DNA double strand breaks (DSBs) which generate chromosomal aberrations, micronucleus formation, sister chromatid exchange, formation of DNA adducts and alterations in DNA r
