Seven fungal species (Aspergillus niger, Aspergillus versicolor, flavus, fumigatus, Rhizomucor pusillus, Trichophyton equinum and Rhizopus oryzae) were isolated from the tannery effluent collected at a industry located Challawa industrial estate of Kano State, Nigeria. niger had highest percentage occurrence frequency 36% (31) while least 4% (5). Consequently, recorded mean tolerance indices 1....

The mitigation of tannery effluents is a rising issue owing to the complex mixture contaminants and hazardous chemicals, mostly chromium. disposal effluent into various water sources such as ponds, lakes, rivers, etc., affects ecosystem aquatic lives. current work scrutinizes performance EC unit for Cr(VI) degradation from real effluent. chromium removal efficiency was evaluated using an iron g...

This study was conducted to determine the spatial levels of chromium contamination of water, agricultural soil, and vegetables in the leather tanning industrial areas using spectrophotometric methods. The results showed elevated accumulation of total Cr ranging from 10.85 ± 0.885 mg/L to 39.696 ± 0.326 mg/L, 16.225 ± 0.12 mg/Kg to 1581.667 ± 0.122 mg/Kg, and 1.0758 ± 0.05348 mg/Kg to 11.75 ± 0....

This study illustrates the process of removal of chromium from chrome tanning waste-water by fly ash which was drive from chrome shaving dust. This experiment was carried out in a batch process with laboratory prepared adsorbent samples and chrome tanning water collected from local tanneries. The influence of various factors likes adsorbent doses, contact time, and initial concentration of chro...

The paper reports the results of an investigation aimed to evaluate the performances of an innovative process for treating tannery wastewater. In such a process biological degradation, carried out in a sequencing batch biofilm reactor (SBBR), is combined with chemical oxidation by ozone. The treatment was carried out at laboratory scale on a real primary effluent coming from a centralized plant...

The effect of Cr(VI) pollution on the corrosion rate of corrugated iron roof samples collected from tanning industry areas was investigated through simulated laboratory exposure and spectrophotometric detection of Cr(III) deposit as a product of the reaction. The total level of Cr detected in the samples ranged from 113.892 ± 0.17 ppm to 53.05 ± 0.243 ppm and showed increasing trend as sampling...
