present study dealt the removal of cr(vi) in a tannery industry wastewater using rice husk silica powder as an adsorbent.the experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different ph against the initial cr(vi) concentration of 292 mg/l. the maximum percentage removal of cr(vi) in the tannery indust...
BACKGROUND The purpose of this study was to test the reliability, validity and factor structure of GHQ-12 questionnaire on male tannery workers of India. We have tested three different factor models of the GHQ-12. METHODS This paper used primary data obtained from a cross-sectional household study of tannery workers from Jajmau area of the city of Kanpur in northern India, which was conducted...
The application of isolated bacterial culture as biological tool for hexavalent chromium removal from tannery industry waste water was investigated. A number of bacteria tolerant to high levels of chromate (>400μgml) were isolated from tannery effluents. These isolates showed varying degree of Cr (VI) reduction under oxic and anoxic conditions at room temperature. Ten isolates were found to be ...
Channa punctatus is the most common fish found in Indian rivers and water bodies. The present study was conducted to investigate the dilution effect of tannery waste water on the activity of serum LDH enzyme of the Indian freshwater fish Channa punctatus. The effect was observed based on the result of chronic toxicity and comparison of control with experimental groups. Tannery wastewater causes...
Tannery industrial effluent is one of the most difficult wastewater types since it contains a huge concentration organic, oil, and chrome (Cr). This study successfully prepared applied bimetallic Fe/Cu nanoparticles (Fe/Cu NPs) for removal. In beginning, NPs was equilibrated by pure aqueous solution at different operating conditions (lab scale), then nanomaterial in semi full scale. The indicat...
