Summary of the filter sources Reduce the concentration of aluminum in drinking water, the optimal treatment process conditions Summary of the filter Reduce the concentration of aluminum in drinking water treatment process conditions Aluminum concentration in drinking water exceeded our country is very serious, in 40 cities nationwide , 32.5% of aluminum in drinking water exceeded 0.2mg / l, and 76.9% in northeastern China. Clearly the issue of reducing the aluminum concentration in drinking water is urgent. In view of the fact that waterworks in our country are mainly based on conventional water treatment processes, it is of practical significance to study the performance of aluminum removal in conventional water treatment processes. If physically divided, the aluminum in the water exists in two states, granular aluminum (aluminum in the solid state) and dissolved aluminum. According to the literature, the calculated theoretical value of total dissolved aluminum in solution is only 0.001-0.004mg / l at pH 6 ~ 7. Aluminum is mainly present in the form of particulate aluminum in water and forms part of the colloidal constituents in the water. According to the basic theory of PAC coagulation, during the hydrolysis and flocculation of PAC, there are both the hydrolysis of PAC and the production of a large amount of hydroxides, as well as the stabilization of colloidal detachment, "collision flocculation" the process of. In the process, the formation of the ferrous sulfate flocculation and the adsorption of the fine particles and the aluminum ions and their complex ions by the large particles have greatly reduced the residual aluminum in the water while removing the fine particles in the water. Therefore, the vast majority of aluminum particles may be coagulation, precipitation, filtration and other conventional treatment processes removed. By optimizing the conventional water treatment process conditions, aluminum can also be removed in addition to turbidity, to meet the water quality standards, is a simple and easy measures. In order to study the relationship between aluminum removal and turbidity removal in the conventional coagulation and sedimentation process of water treatment, laboratory studies were conducted to investigate the effects of coagulant type, dosage, pH value, water temperature, turbidity and other parameters Impact.
