Toxic chemical nature of tannery wastewater makes it difficult to be treated by routine biological treatment processes. Microbes, already present in tannery wastewater can adapt to these conditions and degrade the organics in tannery wastewater. In the present contribution, three bacterial electrogenic strains, tolerant to tannery environment, were isolated from soil contaminated with tannery w...

River pollution due to rapid industrialization and anthropogenic activities adversely affects the aquatic organisms, especially fish. Here, we assessed the genotoxicity, mutagenicity and bioaccumulative aspects of tannery effluents in freshwater murrel, Channa punctatus, an inhabitant of river Ganges. Test specimens were collected from three different polluted sites of the river within and near...

A general overview on the prospective of various oxidation and combined processes in the treatment of tannery industry effluent are reported. Various oxidation and combined processes such as UV/H2O2/Hypochlorites, Fenton and Electro-oxidation, photo-chemical, photo-catalytic, electro-catalytic oxidation, wet air oxidation, ozonation, biological followed by ozone/UV/ H2O2, coagulation or electro...

Under anaerobic conditions, organic pollutants in wastewater are degraded by microbes producing methane and carbon dioxide. The degradation process is effective compared to the more conventional aerobic processes and produces only 5-10% of sludge. This saves considerably on cost associated with the sludge disposal. Among anaerobic technologies, the most popular ones is the upflow anaerobic slud...

Treatment of tannery wastewater is problematic due to high and variable concentrations of complex pollutants often combined with high salinity levels. Two series of horizontal subsurface flow constructed wetlands (CWs) planted with Arundo donax and Sarcocornia fruticosa were set up after a conventional biological treatment system operating at a tannery site. The aim of the CWs was polishing org...

The present study was designed to investigate the effect of industrial pollution on the physical and mental health of the tannery workers as well as the related residential area’s people of Hagaribag in Dhaka city. One hundred and sixty (80 tannery workers and 80 residential area’s people) respondents were selected by purposive sampling method as samples for the present study. Three hypotheses ...

A study was conducted on a group of employees from tannery industries in Telangana state were tested for comet tail lengths that are well established as indicators of early biological effects. To investigate whether occupational exposure to chromium is genotoxic, a total of 92 workers and 80 control groups of individuals in the age group of 16 to 65 years and 6-30 yrs of chromium exposure were ...

The leather tanning industry is one of the industries that causes environmental damage because processes uses copper to produce products such as bags, jackets, and shoes. Copper bioremediation using indigenous bacteria an effective solution problem pollution it utilizes isolated from polluted environment. This study aims isolate characterize copper-resistant waste Yogyakarta Tannery Industry. m...
