Polyaluminum chloride is a solid powder. The color of polyaluminum chloride varies according to the content and basicity, including earthy, brown, brown, yellow, and white. The brown polyaluminum chloride is commonly known as polyaluminum ferric chloride. The raw materials are bauxite, calcium powder, hydrochloric acid, and the same iron oxide powder is added. The production process adopts a two-step acid solution method. The iron powder is to increase the iron content of the finished polyaluminum chloride. With the presence of iron ions, the polyaluminum chloride naturally turns red, so it is brown. The more iron oxide powder is added, the higher the iron content in the finished polyaluminum and the redder the color. This kind of polyaluminum ferric chloride has unexpected effects in sewage treatment. Polyaluminum ferric chloride is used on site, and the iron ions inside enter the sewage, which can accelerate the settlement of flocs, which is faster than ordinary polyaluminum chloride.
