Definition and Working Principle

1.What is an Alumina Filled Filter Cartridge?

The Alumina Filled Filter Cartridge represents a significant advancement in filtration technology. Unlike conventional filter media, this Ceramic Filter Cartridge utilizes specially processed alumina (Al₂O₃) particles with precisely controlled physical characteristics to achieve superior filtration performance.

2.Dual-Action Filtration Mechanism

• Physical Filtration  

The Alumina Filter Cartridge functions as a mechanical barrier, with its precisely engineered pore structure effectively trapping particulate matter through size exclusion. The tortuous pathways created by the alumina particles ensure even sub-micron particles are captured with high efficiency.

• Chemical Adsorption  

   Beyond simple mechanical filtration, the Alumina Filled Filter Cartridge exhibits exceptional chemical adsorption properties. The activated alumina surface contains numerous active sites that form chemical bonds with various contaminants, including:

   • Heavy metal ions (lead, arsenic, mercury)

   • Fluoride compounds

   • Acidic gases (SOx, NOx)

   • Organic impurities

• Ion Exchange Capability  

The Ceramic Filter Cartridge demonstrates selective ion exchange properties, particularly effective in water treatment applications where specific ion removal is required without affecting overall water chemistry.
