Basic aluminum chloride is mostly used in the treatment of various kinds of industrial wastewater, with good flocculation effect, strong filtration, sterilization, deodorization, heavy metal removal, etc., especially in the treatment of high turbidity and high pollution wastewater.
As a traditional water purification agent, basic aluminum chloride has a mature production process. The basic aluminum chloride produced by direct solution of aluminum metal has been eliminated due to its high cost of raw materials and low industrial value. Although the basic aluminum chloride produced by air flow activation process with crystalline aluminum hydroxide as raw material has high product quality and good use effect, it can not achieve satisfactory effect due to complex process and high cost. Using aluminum trichloride as raw material, through electrodialysis and thermal decomposition, although the raw material and energy consumption are small, it has broad prospects, but the relative cost is also high. The quality of basic aluminum chloride produced by precipitation, gel and sodium aluminate neutralization method can not meet the requirements.
At present, the most commonly used and the best basic aluminum chloride production process is to use clay ore and bauxite as raw materials to produce basic aluminum chloride through one-step aluminum ash acid dissolution. The production method of basic aluminum chloride has the characteristics of low cost, low pollution and high product quality.
Although there are many production processes of basic aluminum chloride, the one-step solution of aluminum ash is one of the leading production processes in the world. Understanding the production process of basic aluminum chloride can effectively prevent users from purchasing inferior basic aluminum chloride products.
