Polyaluminum chloride is a very effective water purification agent. The daily consumption of polyaluminum chloride is very large. The continuous fluctuations in the price of polyaluminum chloride in recent times have also affected the sales of polyaluminum chloride. Many customers are waiting and seeing. The rise in the price of polyaluminum chloride this time is entirely due to the market. The continuous price increase of polyaluminum chloride raw materials has led to the continuous rise in the price of polyaluminum chloride. It is estimated that this situation will continue for a long time. Today, Xinhuan Polyaluminum Chloride Manufacturer will explain to you what factors will affect the coagulation and sedimentation of polyaluminum chloride? We know that the effect of polyaluminum chloride flocculation treatment is mainly determined by the dissolution rate of the precipitate, and there are many reasons that affect the dissolution rate of the precipitate. To sum up, there are mainly the following points:
1. The influence of water temperature The dissolution reaction of most precipitating substances is an endothermic reaction, and the solubility increases with the increase of temperature. Therefore, the precipitation process should pay attention to the change of water temperature.
2. The influence of salt effect When there is insoluble salt in water, adding electrolytes makes the saturated insoluble salt become an unsaturated solution, which increases the solubility of the precipitate. This phenomenon is called salt effect. Therefore, in precipitation treatment, it is necessary to avoid the addition of strong dielectric salts to affect the precipitation effect of water purifier.
3. The influence of acid effect The acidity of water has a certain influence on the dissolution rate of the precipitate, which is the acid effect of the precipitation reaction. However, this effect is different for different precipitates. For example, it has little effect on the precipitation of strong acid salts, while the effect of acidity is obvious when precipitating weak acid salts. Therefore, to precipitate weak acid salts, it is generally carried out at a lower acidity as much as possible.
4. The influence of common ion effect When electrolytes containing common ions are added to water, the solubility of the precipitate can be significantly reduced. This is the common ion effect of the precipitation reaction. In the precipitation treatment, the common ion effect is used to appropriately increase the amount of precipitant, accelerate the precipitation treatment, and make the precipitation complete, which can achieve obvious results.
5. Influence of complexing effect In the precipitation treatment, try to avoid adding complexing agents to the water, because complexing agents can often form complexes with the ions to be precipitated in the water, which increases the dissolution rate of the precipitate and affects the precipitation effect.
