Aluminum Sulfate 'or' Non-Ferric Alum Lumps

Aluminum Sulfate 'or' Non-Ferric Alum Lumps that does not contain iron and is used in various industries. It is a purer form of aluminum sulfate compared to ferric alum, which contains iron. Non-ferric alum lumps are a form of aluminum sulfate (Al2(SO4)3) used in various applications like water treatment, paper manufacturing, and leather tanning. Unlike ferric alum, which contains iron, non-ferric alum is a purer form and does not have iron in its chemical composition. It is typically manufactured from aluminum trihydrate and sulfuric acid.
