1.5A: Overview of Methods Chemistry LibreTexts

2021-6-2  Gravity filtration refers to pouring a solid-liquid mixture through a funnel containing a filter paper, allowing the liquid to seep through while trapping the solid on the paper (Figure 1.66a). Suction filtration is a similar process with the difference being the application of a vacuum beneath the funnel in order to pull liquid through the filter paper with suction (Figure 1.66b).

2021-7-15  Gravity Filter Overview: Gravity filters are commonly used in applications where liquid-solids separation is required in a variety of different applications for finish water treatment. Gravity filters can incorporate various types of media such as sand, anthracite, greensand and GAC to meet each plant’s water treatment needs.

A gravity-driven high-flux catalytic filter prepared

Therefore, herein, an efficient gravity-driven catalytic filter was fabricated using a naturally three-dimensional (3D) porous rattan biotemplate for water treatment. After reducing Ag(NH 3 ) 2 + ions via an in situ process that did not involve the addition of reductants or stabilizers, Ag nanoparticles (NPs) were immobilized in the inner microchannel of the porous rattan cane.
