Polyaluminum chloride is widely used as a flocculant in sewage treatment, but in the process of application, there may be different flocculation results of polyaluminum chloride from different manufacturers. What is the reason?
differences in pac suppliers

1. The parameters of polyaluminum chloride are different

The important parameters of polyaluminum chloride are alumina content, Basicity, and pH value. These three parameters are directly related to the flocculation effect of polyaluminum chloride. Polyaluminum chloride produced by different manufacturers will have differences in these parameters, so there will be differences in the flocculation effect.

2. Different raw materials

There are various production processes for polyaluminum chloride. The composition of polyaluminum chloride produced by different processes is different, and the flocculation effect is also different. For example, if some raw materials have a high Iron element, the flocculation effect will be better, but the color of the product will be darker.

3. The influence of other additives

Adding some additives to polyaluminum chloride can improve the flocculation effect. For example, polyaluminum chloride added with dimethyl diallyl ammonium chloride can improve the flocculation effect of polyaluminum chloride in treating low temperature and low turbidity sewage. At present, many manufacturers are researching and developing polyaluminum chloride compound additives to improve the flocculation effect and develop more competitive products.
