Difference between white polyaluminum chloride and polyaluminum sulfate

White polyaluminum chloride and polyaluminum sulfate are very similar, so how should they be used differently?

1. Different shapes. White high-purity polyaluminum chloride (PAC) is a new type of high-efficiency inorganic polymer coagulant. It is made of pure raw materials and advanced technology, and has good flocculation effect. Its water purification effect is better than that of traditional common inorganic salt coagulants and general polyaluminum chloride. Spray drying technology is used for solid products, with iron content of 100ppm. With the development of industry, water consumption increases sharply. However, water resources are limited, so it is necessary to purify the sewage and recycle it.

There are many water treatment methods, but flocculation sedimentation method is the most widely used and low-cost treatment method. Flocculant is the key to flocculation sedimentation method. Polyaluminum sulfate and polyaluminum chloride are widely used flocculants for water treatment. Below white polyaluminum chloride, the appearance is white powder; Polyaluminum sulfate is a white crystal which is easily soluble in water and insoluble in alcohol. The aqueous solution is acidic. The dehydration temperature is 86.5 ℃. It loses crystal water when heated to 250 ℃. Anhydrous aluminum sulfate starts to decompose when heated to 300 ℃.

2. Different purposes. White polyaluminum chloride is mainly used for treatment of domestic drinking water, industrial water supply, oilfield reinjection water, circulating cooling water and various sewage (such as urban domestic sewage, oily sewage, printing and dyeing sewage, papermaking sewage, steel plant sewage, etc.); Papermaking sizing precipitant, sugar refining decolorization clarifier; Used in leather tanning, cosmetics, precision casting and other fields; Polyaluminum sulfate is mainly used in the paper industry, as well as in the purification of drinking water and sewage treatment equipment. It can be used as a medium in textile printing and dyeing, and can be used to adjust the soil PH value.

When choosing to use white polyaluminum chloride and polyaluminum sulfate, it is necessary to distinguish between them and determine the final model according to the needs.
