Granular activated carbon filters purification for potable water treatment (GAC purification foam)
Granular activated carbon (GAC) is a hybrid mixture of a wide variety of graphite platelets that are interconnected by nongraphitic carbon bonding. The adsorptive capacity of GAC makes it ideal for removing a variety of contaminants from water, air, liquids and gases. GAC is also an environmentally responsible product that can be reactivated through thermal oxidation and used multiple times for the same application.

Cell Structure:
Reticulated filter foam operates as a depth-loading filter, as opposed to a surface-loading filter, essentially trapping dust particles within its cells.
The cell structure of filter sponge is remarkable in that each cell has a dodecahedron shape (12 sided), the cell’s walls or “struts” are comprised entirely of organic polymers (polyurethane, polyether, polyester) and the empty space or “windows,” between each strut, comprise 95% – 98% of the filter foam’s mass.
The size, shape & distribution of cells within filter foam can be manipulated during manufacture to provide precisely the desired porosity level, measured in PPI(pores per inch).
10 PPI – 35 PPI pore densities, approximately full scale
Applications:
Activated carbon filter foam can be widely used in daily life and industry such as communication equipment,home appliances,automotive industry, air-conditioner industry,hardware industry,medical equipment industry,instrument tools,bags,furniture,children’s educational toys,physical education equipment, house wares and so on.It’s divided into beginning effect filter foam,amid effect filter foam and high effect filter foam according to the porosity and usage.Concretely,it can be used in Chlorine,Taste, & Odor Removal, Reverse Osmosis Applications, Filtering, Dustproofing, Dedusting and Adsorbing,etc.
