Organic matters in drinking water are composed of soluble and particulate fractions. Soluble organic matters generally originated from allochthonous, autochthonous, and synthetic organic. Silica sand filters, which are utilized in water treatment, have a low potential of removing the soluble organic matters. Traditional carbon-based media such as activated carbon and anthracite are among the choices for the removal of soluble organic. Carbon nanotubes (CNTs) have a higher potential in removing synthetic and natural organic materials than the other traditional carbon based media. Utilization of CNTs at the slurry state requires the removal of the nanotubes themselves at the end of the process which leads to yet another problem to take care of. The present study, therefore, aims at solving this problem. In so doing, oxidized CNTs (140°C, 5 h, Nitric acid) were bound to the surface of silica sand through 3 …
