Using chromium (III) for this purpose offers a multitude of advantages, thus this way of tanning is widely applied. Durin...

It is based on the experiments conducted for study of chromium removal and recovery from chrome tanning waste water of leather industry for chromium removal about 98.5% was achieved at pH 8.0 and at this pH reduction of COD is 61.5 % and percentage for removal of color from the wastewater of leather industry is 99.5% under applying the batch experimental condition. For this purpose, it is carri...

Leather craft products, such as belt, gloves, shoes, bag, and wallet are mainly originated from cow, crocodile, lizard, goat, sheep, buffalo, and stingray skin. Before the skins are used as leather craft materials, they go through a tanning process. With the rapid development of leather craft industry, an automation system for leather tanning factories is important to achieve large scale produc...

Leather industry, one of the polluting industries because of generation of huge amount of liquid and solid wastes, also emits obnoxious smell because of degradation of proteinous material of skin and generation of gases such as NH3, H2S and CO2. Solid wastes are raw trimmings, fleshings, chrome shavings, buffing dusts and keratin wastes. Accumulation of these wastes lead to sludge problem and c...
