Our solid industrial aluminum sulfate is a pale yellow, flake-like solid, produced through a refined process using high-quality bauxite ore, sulfuric acid, and non-polluted groundwater as raw materials, under high temperature and pressure reaction conditions. It is currently primarily used for purifying drinking water and industrial wastewater, sizing in the papermaking industry, clarification in the oil industry, odor and color removal in the petroleum industry, leather tanning, and pigment manufacturing. Iron-free aluminum sulfate, a white, flake-like solid, is employed in post-treatment of titanium dioxide, production of high-grade paper, and as a catalyst carrier.

Our aluminum sulfate is produced in strict accordance with the GB/T 19001-2016/ISO 9001:2015 quality management system and inspected according to national standards. Our focus on meeting customer requirements is our top priority, and we have established stringent internal control standards to ensure the consistent quality of our products. We utilize high-aluminum, low-iron ore for superior quality, and our liquid aluminum sulfate undergoes multiple sedimentation and filtration processes to guarantee excellent product quality.

Our production employs highly technical manufacturing processes and utilizes state-of-the-art equipment. The analytical facilities we use are of the highest precision and sophistication in the industry. We will leverage our robust technical strength to actively promote the technological advancement and quality development of our professional products, inspecting them against internationally renowned quality standards.

The Sales Department is divided into two sections: Domestic Business and International Business. There are 10 domestic business staff members and 11 international business staff members. Over 50% of the sales team holds a university degree. All sales personnel adhere to the philosophy of "Being honest in life and diligent in work." Our products have been sold across all provinces and cities in the country. In the domestic market, we have formed strategic partnerships with several large paper-making and water treatment companies, and our sales volume has been increasing year by year. In the international market, our products are exported to nearly thirty countries and regions in South America, Southeast Asia, the Middle East, Africa, and so on. The stability and high quality of our products have been recognized by overseas customers, and we have become their regular suppliers.
