Activated Alumina


EAN: N/A SKU: N/A Category:



Interteck supplies high quality, competitively priced imported and domestically produced activated alumina.  We also provide activated alumina that can be used as a desiccant in many other applications, including compressed air dryers.

Interteck’s Activated Alumina products are adsorbents which remove contaminants on a combination of chemisorption and physisorption and particulate (or physical) filtration for the removal of metal contaminants from water. Activated alumina, with its many types of adsorptive sites and high surface area, is the perfect choice for the adsorption of various unwanted minerals in water, with proven results for arsenic, high levels of fluoride, copper, zinc, lead and phosphates. There is also the potential for chromium, silica, selenium and mercury.

Activated Alumina Arsenic Removal

In areas with high natural concentrations, arsenic causes arsenic poisoning, as well as having been identified as a contributing factor for different forms of cancer. The identification of this problem has precipitated the lowering of MCL levels in much of the world from 50 ppb (parts per billion) to 5 ppb or less. Used with regeneration, activated alumina was the accepted best technology when compliance levels were less demanding. New requirements needed to be developed for higher uptake capacity and the ability to remove arsenic cost-effectively without regeneration or creating hazardous waste requiring special handling.

Activated Alumina Fluoride Removal

Fluoride is generally felt to be beneficial for dental health at levels up to 1.5 ppm (parts per million). However, at higher levels it has been linked to fluorosis, causing debilitating bone structure disease, as well as discoloration and mottling of teeth. Fluoride at harmful levels occurs naturally in many of the same regions as arsenic in ground water. Due to the higher levels of fluoride as compared to arsenic, regeneration is usually required to make it cost-effective. Promoted products can be provided for applications where regeneration isn’t feasible.
