Sequential batch contactors for removal of chromium (VI) from wastewater using sheep's wool
The effluent streams of various industries contain heavy metals like chromium. The hexavalent form of it is highly toxic, which needs specific intensive treatment before disposal. Sheep’s wool, as a keratinous adsorbent, ...
Treatment of Spent Caustic Using Ionic Liquids
Treatment of spent caustic (SC) wastes from downstream of refineries and petrochemical industries is not only complex but also highly expensive due to its content of high concentration of hazardous compounds, high pH, ...
Model Development, Application and Optimization of Chlorination Breakpoint in Wastewater Treatment
Chlorination in wastewater treatment is regarded as a complicated process due to its ammonia and nitrite content. Chlorine added to such systems reacts with ammonia undergoing episodes of complex reactions, resulting in ...
Removal of Heavy Metals from Wastewater Using Multiwalled Carbon Nanotubes
Recently, carbon nanotubes have been employed as new adsorbent for the removal of many pollutants. In this study, raw multiwalled carbon nanotubes (MWCNTs) were firstly tested for the removal of lead from aqueous solutions. ...
