Application of activated alumina in water treatment

activated alumina water treatment used in the field of water treatment, mainly using its adsorption properties. Removal of contaminants, color and malodor. For example, removal of fluorine, arsenic and phosphorus, decolorization of dye wastewater treatment, papermaking wastewater deodorant alumina in water treatment is the most widely fluoride removal alumina is an amphoteric substance, isoelectric point of about pH = 9.5, when the pH <9.5, alumina adsorption anion pH> 9.5, the alumina adsorption cation
