Nanoparticles-treated particle packs, such as sand beds., may effectively filter and purify liquids such as waste water. When tiny contaminant particles in waste water flow through the particle pack, the nanoparticles will capture and hold the tiny contaminant particles within the pack due to the nanoparticles surface forces, including, but not necessarily limited to van der Waals and electrostatic forces. Coating agents such as alcohols, glycols, polyots, vegetable oil, and mineral oils may help apply the nanoparticles to tie particle surfaces in the filter beds or packs.
Des pièges formés de particules traités avec des nanoparticules, tels que des lits de sable, peuvent filtrer et épurer efficacement des liquides tels que des eaux usées. Lorsque de minuscules particules de contaminant présentes dans les eaux usées traversent le piège formé de particules, les nanoparticules piègent et retiennent les minuscules particules de contaminant dans le piège du fait des forces de surface des nanoparticules, telles que la force de Van der Waals et les forces électrostatiques. Des agents de revêtement tels que des alcools, des glycols, des polyols, de l'huile végétale et des huiles minérales peuvent faciliter l'application des nanoparticules sur les surfaces de liaison dans les lits filtrants ou les pièges.
