The production of activated alumina from aluminum hydroxide based waste
TLDR
In this paper, the authors investigated the production of activated alumina from aluminum hydroxide-based waste from the Seydisehir Eti Aluminum Works and found that the results showed that aluminum hydoxide based waste could be converted to activated alumine effectively by using a combination of acid and heat activation processes.About:

TL;DR: This work provides the most complete and detailed characterization of AAW including chemical, physical, thermal, and microstructural analysis and suggests many other possibilities that have not been explored thus far.
Study on the effectiveness of activated alumina in removing arsenic from groundwater
TL;DR: In this article, the effects of a number of parameters including oxidation state of arsenic, pH, iron, chloride, sulfate; phosphate, activated alumina size, empty bed contact time and the regeneration of spent alumina in removing arsenic by activated aluminina were evaluated.

Arsenic in drinking water-problems and solutions
TL;DR: In this article, column studies were conducted at the University of Regina to examine oxidation with KMnO 4 followed by filtration using manganese greensand and ironoxide coated sand to examine the removal of arsenic from drinking water; these results were compared with the data from ion exchange studies.

Elimination of phosphorus from municipal and industrial waste water
TL;DR: In this article, two processes for phosphorus removal from waste waters were developed which avoid these disadvantages: a process especially suitable for low phosphorus concentrations (≤1 mg/L P) employing Activated Alumina for the removal of the phosphate by adsorption.
