Application
‹1› Aluminum sulfate is a widely used industrial reagent, usually mixed with alum. Aluminum sulfate is usually used as flocculants for water purification and sewage treatment facilities were also used for the paper industry.
‹2› Under natural conditions, little to no aluminum sulfate salt form. It will form a hydrate, including 16 water aluminum sulfate is the most common.
‹3› Aluminum sulfate is also a very effective insecticide mollusks can kill the Spanish slug (Spanish slugs).
‹4› Aluminum sulfate for water and in textile dyeing and printing as a medium. In water purification, it makes impurity condensation, sedimentation and filtration easier.
‹5› When dissolved in a large number of neutral or slightly alkaline water, the produced precipitate of aluminum hydroxide, Al (OH) 3. When dyeing fabric, aluminum hydroxide gel makes it easier to dye attached to the top of plant fiber.
‹6› Aluminum sulfate is also used to adjust soil pH, because it is also hydrolysis of aluminum hydroxide produced a small amount of dilute solution of sulfuric
