The contents presented in this paper focuses on the performance of UASB (Upflow Anaerobic Sludge Blanket) reactor for treating various industrial and domestic wastewaters at various operating conditions. The reactors can be used conveniently for the treatment of tannery, distillery, food processing, metal mining, dairy, domestic wastewater etc. The performance of the reactor mainly depends on t...

A fungal tannase was produced, recovered, and immobilized by entrapment in calcium alginate beads. Catalytical properties of the immobilized enzyme were compared with those of the free one. Tannase was produced intracellularly by the xerophilic fungus Aspergillus niger GH1 in a submerged fermentation system. Enzyme was recovered by cell disruption and the crude extract was partially purified. T...

The emission of tannery effluents into the environment may cause serious harm to human and environmental health. Nevertheless, few studies have investigated the possible effects of intake of these effluents in mammalian. Thus, this study aimed to evaluate the neurobehavioral effects of chronic intake of different tannery effluents concentrations (0.1%, 1% and 5%) (120 days) in male C57BL/6J mic...

Hazardous solid wastes may pose a serious risk to human health and to the environment, if not managed appropriately and disposed of safely. In this study, the effective stabilization of tannery sludge, a toxic industrial solid waste produced from the physico-chemical treatment of tannery wastewaters, was examined by the addition of ladle furnace slag (LFS), another industrial solid waste. Moreo...

Zirconia ultrafiltration membranes are widely developed and used for past several years. But the conventional sol-gel methods of zirconia membrane preparation involve many steps. In the present study an attempt was made to develop defect free zirconia ultrafiltration (UF) membrane in single step coating of zirconia nanopowder suspension by slip casting method over multichannel ceramic support. ...

Chromium (Cr) is the most important element used to leather industry is still considered to be the most important industries which pollute the environment by chromium metal. Removal of heavy metals dissolved at low concentrations in water and wastewaters is often a problem that can be solved in different ways. This paper describes a study conducted to determine the recovery of chromium from tan...

This work aims to study the ability of using single and sequential electro-Fenton (EF) electrocoagulation (EC) processes in order treat tannery wastewater. The first method was run with an air diffusion cathode for H2O2 generation boron–doped diamond (BDD) as anode. second conducted mild steel electrodes. applied processes' performance monitored by removals chemical oxygen demand (COD) along to...
