The activity of alanine aminotransferase (ALAT) and aspartate aminotransferase (AAT) of different tissues of fingerlings of Labeo rohita under the influence of two effluents has been studied. The alanine aminotransferase activity was increased over the control in different exposed periods of tannery and distillery effluent treatments. The alanine aminotransferase in the liver showed increased a...

Assessments of chromosomal integrity and structure enable the prevention of diseases associated with the work environment, with the frequencies of chromosomal aberrations and micronuclei often being used as markers in biomonitoring. Owing to their routine manipulation of potentially toxic chemicals, tannery workers as a group merit a more thorough evaluation and discussion. This study investiga...

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. Though, this waste stream is compri...

This study was initiated to evaluate and optimize the conversion of animal fat from tannery wastes into methyl ester. In the pre-treatment stage, animal fats feedstock was hydrolysed and esterified through solid state fermentation (SSF) using Microbacterium species immobilized onto sand silica matrix. After 72 hours of fermentation, predominant esters in the animal fats were found to be with 83...

Efficient treatment of tannery effluent is one of the serious problems faced for the past few decades. Since these industrial effluents contain more organic pollutants the most favorable option to treat this is by biological treatment process. In this study a lab scale submerged aerobic flat sheet membrane bioreactor was operated under gravity drain operation for the treatment of tannery efflue...

This research study investigated ways of rationalizing chemical water and energy consumption usage and reducing waste discharge in a tannery. The work was motivated by the need to achieve sustainable development through the use of best practices to achieve compliance with environmental regulations through the application of Cleaner Production initiatives. The processes involved stripping of ove...

This paper illustrates systematic development of a convenient analytical method for the determination of chromium and cadmium in tannery wastewater using laser-induced breakdown spectroscopy (LIBS). A new approach was developed by which liquid was converted into solid phase sample surface using absorption paper for subsequent LIBS analysis. The optimized values of LIBS parameters were 146.7 mJ ...

in the present study, the treatment of tannery wastewater was performed by electrocoagulationmethod (ec) using aluminium and steel electrodes. response surface methodology (rsm) with three factors; current density (i), electrolysis time (t) and ph, with each factor at five levels, was used to optimize the factors for higher chemical oxygen demand (cod) and total suspended solids (tss) removal. ...

Tannery wastewater contains several detrimental constituents that severely affect concrete durability. It can also cause soil and water pollution from discharge of untreated effluent if not properly contained. Therefore, ensuring proper protection tannery treatment plants is extreme importance to prevent leaching hazardous wastewater. Properly proportioned blended cement usually required for co...
