This study attempts to understand the socio-economic conditions and working condition of leather tannery workers. The leather tanning industry and leather related industry give employment and business opportunities for many people. The rising cost of living compels the tannery workers to take up the job. The tannery workers are exposed to lot of chemicals for low wages. But this leads to health...

The expanded granular sludge bed bioreactor appears today as a cheap, robust and more popular technology because it operates using a fluidized bed, which allows increasing in organic load and in cell retention times, generating higher treatment efficiencies (up to 95 %) and renewable energy (i.e., biogas, biomethane, and biohydrogen). Nevertheless, the efficiency of this bioreactor mainly depen...

BACKGROUND Tannery workers are at considerable risk of developing occupational contact dermatitis. Occupational skin diseases in tannery workers in newly industrialized countries have been reported, but neither the prevalence of occupational allergic contact dermatitis nor the skin-sensitizing agents were specifically examined in those studies. OBJECTIVES To assess the prevalence of occupatio...

The city of Sialkot in Pakistan is a hub leather tanneries, with approximately 260 tanneries operation and, while producing millions products per day, the discharges gallons untreated effluent into drains each day. In order to devise cost-effective system for treatment tannery wastewater, floating wetland (FTW) was established treat using local plant species through phytoremediation. efficiency...

Abstract The tannery industry inevitably generates toxic and catastrophic wastewater, which results in a huge threat to public health water resources. Therefore, this work aimed synthesize parthenium hysterophorus-based biochar–Fe 3 O 4 composite for removal of Cr(VI) from wastewater under full factorial experimental designs the Box–Behnken, was analyzed using response surface methodology four ...
