The difference between polymerized alumina and polymerized iron oxide

Polyaluminium chloride and polychlorine Chemical iron can effectively adsorb impurities that precipitate sewage in water treatment, and their effects vary depending on the water quality. TodayShanghai Kaiyin Chemical Let me introduce to you these two aggregation products with similar names——Aggregation The difference between aluminum chloride (PAC) and polyferric chloride (PFC)!

We distinguish from the following four points:

1. Appearance: Polyaluminium chlorideThe colors are generally white, yellow, and tan, while polyaluminum chloride with an aluminum trioxide content between 27% and 30% within the national standard is mostly khaki, to yellow, or light yellow solid powder. Polyferric chloride is generally a light yellow, yellow or brown powder;

2. Application scope: Polyaluminum chloride in the purification of river water The effect is outstanding. The treated water has outstanding effect. The water quality is soft and will not cause the fabric to become stiff. However, polyferric chloride has a short time and quick effect in the purification process of wastewater from steel mills, paper mills, sewage plants, etc. The treated water quality is clear and it is easier to meet the discharge standards.

3. Production raw materials: Polyaluminum chlorideEspecially drinking water grade requires the use of aluminum hydroxide powder materials for processing and production, while polyferric chloride requires the use of aluminum calcium powder as raw material for processing.

4. Function: Polyferric chloride can only be used in industrial water treatment, while polychlorination Aluminum can be used in drinking water and industrial water treatment.
