The Role of Fluoride Remover in Aluminum Casting Wastewater
In the aluminum casting industry, the wastewater treatment is a key part, the problem of fluorine pollution is particularly prominent. The fluoride remover of aluminum casting wastewater has become an important means to solve this problem.
In the process of aluminum casting, whether the fluorine additives used or in the aluminum ore treatment process will lead to the large amount of fluoride ions in the wastewater. Once these fluoride wastewater is discharged into the environment untreated, it will cause serious harm to soil, water and organisms. In soil, fluoride ion can change the physico-chemical properties of soil and affect the absorption of nutrients by plant roots, leading to poor plant growth and even death. After entering the water body, the water quality will deteriorate and endanger the survival of aquatic organisms. Drinking water containing excessive fluoride for a long time will also seriously affect human health and cause diseases such as dental fluorosis and bone osis.
The fluoride removal agent of aluminum casting wastewater removes fluoride ions through various mechanisms of action. Chemical precipitation fluoride remover, such as calcium salts, can react with fluoride ions to form insoluble calcium fluoride precipitation, thus separating fluoride ions from wastewater. Adsorption fluoride removal agent uses its own special structure, such as activated alumina, etc., which has a strong adsorption capacity of fluoride ions, and the fluoride ions are adsorbed on its surface, to achieve the purpose of fluoride removal.
The use of aluminum casting wastewater fluoride remover has significant advantages. It can effectively reduce the concentration of fluoride ions in the wastewater, so that the wastewater meets the discharge standard. Moreover, the use of fluoride agent is relatively simple, only according to the fluoride content and water quality characteristics of wastewater, reasonable adjustment of the amount of addition and reaction conditions, can achieve good fluoride effect. In addition, fluoride remover has a good adaptability to different types of aluminum casting wastewater, and can effectively deal with all kinds of complex wastewater conditions.
