Progress in Emerging Contaminants Removal by Adsorption/Membrane Filtration-Based Technologies: A Review

Metals Removal Technologies for Stormwater: Filtration

This study, sponsored by the Water Environment Research Foundation, focused on innovative methods for the capture of metals from stormwater. The two areas of focus were media filters and swales. This paper will focus on the filter studies. Twelve media were chosen for initial evaluation. Equilibrium and kinetic studies were formed on these media to assess their performance in capturing metals f...

Sulfate Radical Technologies as Tertiary Treatment for the Removal of Emerging Contaminants from Wastewater

Water scarcity and water pollution is a worldwide problem and has driven research into eco-friendly and low-energy cost efficient remediation. The reuse of wastewater for non-potable purpose after proper treatment is the only sustainable solution to the problem. Advanced oxidation processes (AOP) based on the in-situ generation of hydroxyl radicals have been intensively investigated for this pu...

Organic Micropollutant Removal by Biological Activated Carbon Filtration: A Review

Removal of contaminants in a paper mill effluent by Azolla caroliniana

This study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by Azolla caroliniana.  The experimental investigations have been carried out using Azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), pH (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). Th...

Removal of Metallic and Organic Contaminants from Aqueous Streams by Novel Filtration Methods

Graphite nanofibers, are a novel material that has been developed in our laboratory from the metal catalyzed decomposition of certain hydrocarbons (1). These structures possess a cross-sectional area that varies between 5 to 100 nm and have lengths ranging from 5 to 100 mm (2). High-resolution transmission electron microscopy studies have revealed that the nanofibers consist of extremely well-o...
