Activated Alumina process is one of the widely used adsorption methods for the defluoridation of drinking water. Aluminum salts are applied in water treatment for precipitation reactions. Although aluminum compounds (e.g. Aluminium and fluorine in drinking water have been linked with dementia but uncertainties remain about this relationship. Aluminum salts are commonly added as coagulants during water treatment to remove turbidity, organic matter and microorganisms. The allowable level for aluminum in drinking water is currently set at 0.05 to 0.2 parts per million (PPM). The effect of fluoride on bone has been extensively investigated as a therapy for osteoporosis and as a toxic agent in fluorosis. Aluminum-copper alloys are of two types: (i) alloys containing copper and aluminum (known as aluminum bronze) and (ii) alloys containing copper, aluminum and zinc (known as aluminum brass). The compound is used as a desiccant (to keep things dry by absorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water. Aluminum in water seldom is a concern for municipal water systems. In: Water S.A. 25 (1), pp. Adding aluminum sulphate and lime to water causes aluminum hydroxide formation, which leads to settling of pollutants. Administered in drinking water at low concentrations (1 ppm), fluoride protects against dental caries (Murray et al., 1990). Aluminum is an extremely abundant metal in the earth’s crust. It’s why we’ve never sold a plastic bottle and never will. Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. The aluminium in drinking water alone is harmless to the human organism, it depends on the total intake per day.
