High Pure Calcium Aluminate For Polyaluminium Chloride Production

Polyaluminum chloride (PAC) special calcium aluminate powder is a key raw material used to produce high-efficiency water treatment agent polymer aluminum chloride.

Its product highlights are mainly reflected in the following aspects:

1. High aluminum content to improve PAC quality High aluminum dissolution rate: The content of alumina (Al₂O₃) in calcium aluminate powder is high (usually ≥50%), has strong reactivity, and can significantly increase the aluminum content of polymer aluminum chloride (the salt basis is adjustable), thereby enhancing its flocculation effect. Few impurities: Production of selected raw materials, low content of impurities (such as heavy metals, insoluble matters), ensures the purity of the final PAC product and meets drinking water treatment standards.

2. Strong reaction activity and high production efficiency Rapid reaction: Calcium aluminate powder dissolves rapidly in hydrochloric acid, and the reaction conditions are mild (just at normal pressure or low temperature), shortening the production cycle and reducing energy consumption. Wide process adaptability: suitable for a variety of production processes (acid-soluble method, alkali-soluble method), can flexibly adjust production parameters to meet different PAC specifications (liquid or solid) needs.

3. Significant cost advantage High raw material utilization rate: The aluminum dissolution rate of calcium aluminate powder can reach more than 90%, reducing raw material waste and reducing production costs. Convenient transportation and storage: The powder form is easy to transport and store, and the amount is small (compared to traditional raw materials such as bauxite), and the overall cost is lower.

4. Environmental protection and sustainability Little waste residue: the amount of residue after reaction is low, and the residue can be recycled (such as building materials), meeting the requirements of green production. Low energy consumption: no need for high temperature and high pressure during the production process, reduce carbon emissions, and comply with environmental protection policy orientation.

5. Strong product stability High batch consistency: A strict quality control system ensures the stability of the calcium aluminate powder composition and avoids quality problems caused by fluctuations in raw materials during PAC production. Storage resistance: The powder has stable properties and is not prone to moisture or clumping for long-term storage, ensuring production continuity.

6. Wide application areas The produced polyaluminum chloride can cover a variety of water treatment scenarios, including: Municipal drinking water purification Industrial wastewater treatment (electroplating, printing and dyeing, papermaking, etc.) Domestic sewage and sludge dehydration Adapt to different water quality conditions (such as high turbidity, low temperature and low turbid water). Summarize As the core raw material of polymer aluminum chloride, calcium aluminate powder has become the key to improving quality and efficiency in the water treatment industry with its high activity, low cost, environmental protection and stability. Its highlight is not only improving PAC performance, but also helping enterprises achieve a balance between economic benefits and environmental responsibility by optimizing production processes.
