PAC is a white powder with high purity aluminum hydroxide, hydrochloric acid by spray drying the processing of a white or milky white powder-like fine powder, exposed in the air, easily melted. Also known as: spray drying PAC.

It is compared with the ordinary polyaluminum sulfate has the following characteristics:
1. AL2O3 content is high, "29.5%
2. Basicity low, only 50%, while the average basicity of poly aluminum about 90%
3. Water insoluble small, only 0.3%, while the average poly aluminum with 2% or more.
4. Color pure, aqueous solution of the product of the water is clear and transparent, without any color, while the ordinary aqueous poly aluminum color yellow or brown.
