polyaluminium chloride

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.

Safe and reliable Drinking water grade safety: low heavy metal content, comply with international standards (such as NSF/ANSI 60), ensuring drinking water safety. No secondary pollution: No toxic residue after reaction, ensuring the quality of the effluent.

High-efficiency coagulation performance Rapid precipitation: form dense flocs, accelerate solid-liquid separation, and improve processing efficiency. Widely applicable: adapts to different pH values, water temperature and turbidity (including low temperature and low turbid water), and the treatment effect is stable.

Low temperature and low turbidity treatment: Excellent performance for winter or high turbidity raw water (such as Yellow River water, algae water), the flocs are dense and not easy to break.

Low impurities/heavy metals: High-purity raw materials (such as aluminum hydroxide or calcium aluminate powder) and advanced processes. The content of heavy metals (such as lead and arsenic) is much lower than the national standard, and has passed the international certification of FDA, EU, etc., and is suitable for highly sensitive fields such as direct drinking water treatment, food processing, and pharmaceutical preparations.

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.

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.

Rapid flocculation: Strong charge neutralization ability, dense alum flower forms within 5 to 10 seconds, and the settlement speed is more than 30% faster than ordinary PAC, greatly shortening the water treatment cycle. Wide pH adaptability: efficient operation within the pH range of 5-9, no need to adjust the pH frequently, and reduce operation complexity and cost.

Ultra-high purity and safety No residual risk: After treatment, there is no hidden danger of aluminum ion residue exceeding the standard, and it complies with the WHO drinking water safety standards. Rapid flocculation: Strong charge neutralization ability, dense alum flower forms within 5 to 10 seconds, and the settlement speed is more than 30% faster than ordinary PAC, greatly shortening the water treatment cycle. Wide pH adaptability: efficient operation within the pH range of 5-9, no need to adjust the pH frequently, and reduce operation complexity and cost.
