Dyes wastewater produced during leather processing caused serious environmental pollution. Anionic dyes are always vital crisis in waste treatment. Removal of anionic dyes from tannery wastewater before their discharge into the environment is important for health and environment safety. The use of low-priced and biodegradable adsorbents could be a good method to minimize the environmental impac...

Chromium is abundant in nature and has a dominant presence in most of the effluent streams as compared to other heavy metal ions. The presence of highly toxic and carcinogenic hexavalent chromium (Cr(VI)) in effluent streams is a major environmental issue. The electroplating and tannery industry effluents are the major source for the Cr(VI) production in wastewater streams. The present work dea...

Textile industry processes are among the most environmentally unfriendly industrial processes; because, they produce color wastewater that is heavily polluted the environment. Therefore, textile industry wastewater has to be treated before being discharged into the environment. In this study, experiments were conducted for different process parameters like nutrient dosage and dilution ratio aga...

the effluents of tannery industries are the major source of chromium contamination in thegroundwater. in most of the sub-urban areas ground water is the major source of drinking water. for humanbeing long term exposure to chromium is detrimental. the main objective of this study is to assess thegroundwater contamination and to adopt appropriate methods and to develop suitable techniques either ...

Tannery wastewater is considered one of the most contaminated and problematic wastes since it consists considerable amounts organic inorganic compounds. These contaminants result in high chemical oxygen demand (COD), biochemical (BOD), total suspended solids (TSS). In this work, heterogeneous photodegradation recalcitrant COD from tanning industry was investigated, particular due to presence ve...

Heavy metals pollution has become a more serious environmental problem in the last several decades as a result releasing toxic materials into the environment. Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical processes were used for the treatment of domestic, industrial and agricultural effluents. The commonly used conventional biological treatmen...

Introduction Effluents from leather industries contain high organic and inorganic loadings, and dissolved and suspended solids1,2. Apart from chemicals used in tanning process, other chemicals released from skin and hide contribute chemical oxygen demand (COD, 1000-4000 mg/l), biological oxygen demand (BOD, 300-800 mg/l) and total organic carbon (TOC, 350-1500 mg/l) of wastewater. Syntans (synt...

Emission of high chrome tanning wastewater is catastrophic for the environment. In this work, effectiveness coir pith charcoal stated removal chromium from tannery wastewater. The yield was 2.4%. prepared characterized by Fourier transform infrared spectroscopy (FT-IR). efficiency assessed experimenting with various parameters e.g., dose, contact time, and relative pH. content in raw after trea...
