Model Development, Application and Optimization of Chlorination Breakpoint in Wastewater Treatment
(2017-12)
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 ...
Development of Activated Carbon Fibers for Organic Removals
(2017-11)
Phenols are classified to be one of the most hazardous pollutants found in wastewater. They are discharged into rivers, lakes and seas, causing adverse effects on the enviromental and human health. Adsorption is a well-known ...
Iterative Methods for the Solution of a Steady State Biofilter Model
(2017-11)
Biofilter modeling helps in understanding the biofiltration process and designing of full-scale biofilters. The biofilter models with complex kinetics do not have analytical solutions and numerical algorithms are typically ...
Treatment of Spent Caustic Using Ionic Liquids
(2017-04)
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, ...
Removal of Heavy Metals from Wastewater Using Multiwalled Carbon Nanotubes
(2017-04)
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. ...
Sequential batch contactors for removal of chromium (VI) from wastewater using sheep's wool
(2017-05)
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, ...
