Currently, the continuous price increase in the polyaluminum chloride industry is unfavorable to most sewage treatment plants. So, what is the next development of polyaluminum chloride?

In recent years, China's polyaluminum chloride industry has developed rapidly, but the scale of manufacturers is relatively small, and the regional characteristics of industrial development are obvious, mainly distributed in Henan, Shandong, Jiangsu, Zhejiang,etc. China has abundant sources of raw materials, which makes the production cost of polyaluminum chloride relatively low. There are many production processes for polyaluminum chloride. Polyaluminum chloride products are prepared from raw materials such as aluminum scraps, aluminum ash and aluminum slag. The process is relatively simple, and the early development is relatively rapid. However, in recent years, due to the rising prices of aluminum-containing materials and the availability of other higher-value aluminum-containing products, the use of above materials has been decreasing.

In recent years, the state has strengthened the efforts to control the private mining of mineral resources, and aluminum ore, which is the main raw material of polyaluminum chloride, has also become tense and the price has continued to rise. Therefore, the cost of enterprises has increased, and some small backward devices have been eliminated. According to statistics, currently domestic polyaluminum chloride products with content below 28% still account for more than 60% of the total output, mainly used in sewage treatment in papermaking, dyestuff, chemical and other industries.

According to relevant departments, the national environmental protection policy requires that all new projects this year must meet environmental protection standards, and the sewage treatment measures must be qualified. Driven by this, the polyaluminum chloride industry will usher in a new round of growth.
