Conventional leather dyeing consumes high amounts of dyes and increases pollution tannery wastewater. We have focused on the reduction dyestuff avoidance water additional chemicals for colorization leather. Waterless with supercritical CO2 as solvent dye 1-(methylamino)anthraquinone was performed in a technical scale autoclave. The intensity uniformity dyed leathers assessed using spectroscopic...

The leather tanning industry is one of the industries that causes environmental damage because processes uses copper to produce products such as bags, jackets, and shoes. Copper bioremediation using indigenous bacteria an effective solution problem pollution it utilizes isolated from polluted environment. This study aims isolate characterize copper-resistant waste Yogyakarta Tannery Industry. m...

The tannery industry is characterized by the consumption of a large quantity water, around 30–40 m3 for processing 1000 kg hide or skin. This amount becomes wastewater, containing about 300 different chemicals, mainly refractory organic compounds, with high chemical oxygen demand (COD), total dissolved salts (TDS), chromium, and evolution toxic gases, such as ammonia sulfides, etc. remaining ta...

Efficient water management is a priority in the European Union, since the operational efficiency of many water utilities is very low compared to best practice. Several countries are restructuring the water industry to save costs. Larger-scale operations and vertical integration are promoted to achieve scale and scope economies; however, the literature is not unanimous that such economies exist....

electroplating industry wastewater (eiw) characterized by high chemical oxygen demand (cod) is a big source of water and air contamination with heavy metals. the formation of cyanide complex with heavy metals is responsible for its elevated cod. the concentration of heavy metals in eiw can be removed by the use of different precipitating agents (sulfide and hydroxide). but the major bottleneck ...

introduction: the objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using  coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. methods: this is an applied study. with regard to shiftwork schedules of the fact...

Textile industry can be classified into three categories viz., cotton, woolen, and synthetic fibers depending upon the used raw materials. The cotton textile industry is one of the oldest industries in China. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Wastewater from printing...
