Activated alumina defluorination agent appears as white spherical particles. It has a large defluorination capacity, good physical properties, and high compressive strength. It does not soften, expand, or crack when soaked in water, and is stable and reliable in use, easy to regenerate, and has a long service life. Water purified by activated alumina defluorination agent combined with corresponding filtration equipment can meet the water quality standard of 1mg/L, achieving significant defluorination effects. It can be used as a defluorination filter material in drinking water defluorination or other industrial water treatment devices.
