Carbon Nanostructures Production by AC Arc …

Carbon nanostructures have received much attention for a wide range of appliions. In this paper, we produced carbon nanostructures by decomposition of benzene using AC arc discharge plasma process at atmospheric pressure. Discharge was carried out at a voltage of 380 V, with a current of 6 A–20 A. The products were characterized by scanning electron microscopy (SEM), high-resolution

Biological Activated Carbon Process for Water …

2020-8-9 · The biologically enhanced active carbon process is an option for many water utilities. Granular activated carbon (GAC) has been used extensively for the removal of dissolved organics from drinking water. In the early seventies, it was reported that bacteria which proliferate in GAC filters may be responsible for a fraction of the net removal of organics in the filter.
