Description
Technical Parameters
Product Description
The Carbon Block Pre-Filter is a highly efficient water treatment equipment, the core of which is to use the strong adsorption capacity of activated carbon to purify water. Secondly, the working principle of the carbon block pre-filter is mainly based on the physical adsorption and chemical adsorption of activated carbon. Physical adsorption refers to the intermolecular force between the surface and pores of activated carbon that can attract and fix impurity molecules in water. This adsorption is usually reversible. When the adsorption reaches saturation, its adsorption capacity can be restored by appropriate treatment (such as backwashing or replacing activated carbon).
