Removal of bromide and bromate from drinking water using granular activated carbon

Removal of bromide and bromate from drinking water using granular activated carbon.

Granular activated carbon (GAC) was used to remove bromide (Br⁻) and bromate (BrO(3)(-)) from drinking water in both bench- and pilot-scale experiments. The present study aims to minimize BrO(3)(-) formation and eliminate BrO(3)(-) generated during the ozonation of drinking water, particularly in packaged drinking water. Results show that the Br⁻ and BrO(3)(-) levels in GAC-treated water decrea...

Removal of bromide and iodide anions from drinking water by silver-activated carbon aerogels.

The aim of this study is to analyze the use of Ag-doped activated carbon aerogels for bromide and iodide removal from drinking water and to study how the activation of Ag-doped aerogels affects their behavior. It has been observed that the carbonization treatment and activation process of Ag-doped aerogels increased the surface area value ( [Formula: see text] ), whereas the volume of meso-(V(2...

Nitrate Removal from Aqueous Solutions Using Granular Activated Carbon Modified with Iron Nanoparticles (RESEARCH NOTE)

Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...

Removal of Humic Substances from Water Using Solar Irradiation and Granular Activated Carbon Adsorption

Removal of Pesticides from Water Using Granular Activated Carbon and Ultrafiltration Membrane—A Pilot Plant Study

The use of powdered activated carbon for fouling control in the membrane processes is limited by some secondary problems associated with its use, like cake formation, long backwash times and blackening of pipes. Granular activated carbon (GAC) was used as an alternative of powdered activated carbon due to its large particle size which was kept from being entering into the membrane system. The s...
