Aluminum Sesquichlorohydrate vs Aluminum Chlorohydrate
Comparison of Aluminum Chloride and Polyaluminium Chloride
Aluminum Sesquichlorohydrate and Aluminum Chlorohydrate, both of which are used in the chemical industry, have obvious functions in many fields. Let's try to analyze the similarities and differences between the two.
Let's talk about its preparation first. The preparation of basic aluminum chloride is often made of aluminum ash, aluminum chips, etc., through various processes such as acid dissolution, hydrolysis, and polymerization. This process requires precise temperature control, time control, and material ratio to obtain high-quality products. The preparation of polyaluminium chloride is either obtained by reacting aluminum hydroxide powder with hydrochloric acid, or by baking and acid leaching of bauxite. The process also needs to be carefully controlled, and all links must not be wrong.
Second discussion on its properties. Basic aluminum chloride is mostly black or tan powder in appearance. It has a high salinity and a fast hydrolysis rate in water. It can quickly form aluminum hydroxide colloids and absorb impurities in water. Polyaluminum chloride is mostly yellow or light yellow solid. The salinity is slightly lower than that of basic aluminum chloride, but its stability is good. The colloidal particles formed after dissolution are more uniform, and the adsorption and bridging ability is also strong.
As for the use, both are widely used in water treatment. Basic aluminum chloride is very popular when treating high turbidity water and low temperature and low turbidity water because of its rapid hydrolysis and good sedimentation effect. For example, the purification of river and lake water can quickly remove large particles of impurities such as sediment and algae in water. Polyaluminum chloride, with its stability and adaptability to various water quality, can play a good role in drinking water and industrial wastewater treatment. It can not only remove turbidity, but also effectively remove heavy metal ions and organic matter in water to ensure water quality safety.
Let's take a look at the advantages of the two. Basic aluminum chloride has relatively low cost and a wide range of raw material sources. It can effectively reduce treatment costs in large-scale wastewater treatment. Polyaluminum chloride is used in applications with high water quality requirements, such as urban tap water production. It shows excellent purification ability and can make water quality meet high standards.
However, both also have shortcomings. Basic aluminum chloride has a dark color, and the treated water may leave a little color, which affects the appearance. Although polyaluminum chloride has excellent performance, its price is relatively high, and its application may be limited in cost-sensitive projects.
To sum up, basic aluminum chloride and polyaluminum chloride have their own advantages and disadvantages. In practical application, when considering factors such as water quality, treatment requirements and cost budget, choose carefully to make each of them develop their strengths to achieve the best treatment effect.
