For professionals in water treatment, paper manufacturing, and other industrial sectors, understanding the precise specifications of chemical inputs is paramount. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of quality control and provides detailed information on our industrial grade aluminum sulfate. Our offerings, such as aluminum sulfate AL2O3 16%, are formulated to meet rigorous industry standards, ensuring optimal performance and reliability.

The chemical formula for hydrated aluminum sulfate is Al₂(SO₄)₃·nH₂O, with the most common form being the octadecahydrate (n=18). The key indicator of quality for industrial aluminum sulfate is its aluminum oxide (Al₂O₃) content. Our product consistently meets or exceeds the minimum requirement of 16% AL2O3, which is crucial for its effectiveness as a flocculant and chemical auxiliary.

Equally important are the impurity levels in industrial chemicals. NINGBO INNO PHARMCHEM CO.,LTD. ensures that our aluminum sulfate has very low concentrations of potentially harmful elements. For instance, the iron (Fe) content is strictly controlled to be ≤0.005%, arsenic (As) ≤0.0001%, lead (Pb) ≤0.0005%, cadmium (Cd) ≤0.0001%, mercury (Hg) ≤0.00001%, and chromium (Cr) ≤0.0005%. These low impurity levels are critical, especially when the product is used in drinking water purification, safeguarding public health and environmental integrity.

The physical appearance of our industrial aluminum sulfate is typically a white crystal powder or flakes, making it easy to handle and dissolve. Water insolubles are kept to a minimum, generally ≤0.1%, ensuring that the active compound dissolves readily. The pH of a 1% solution is maintained at ≥3, indicating its acidic nature which is beneficial for many applications.
