Aluminum Sulphate in Drinking Water- Is it Safe

Aluminum is used in water treatment to remove disease-causing microorganisms and other drinking water impurities that can affect your health. When properly treated, the amount of residual aluminum left in the water should be similar to or lower than the non-treated water. Aluminum can be removed to extremely low levels by point-of-use treatment ...

A New Process For Sulfate Removal From Industrial Waters

Process Description. The most common method for removing high concentrations of sulfate from water is through addition of hydrated lime (Ca (OH)2), which precipitates calcium sulfate: Na 2 SO 4 + Ca (OH) 2 => CaSO 4 + 2 NaOH Calcium sulfate, which hydrates to become the common mineral gypsum, has a solubility of approximately 2000 mg/L as sulfate.

Should I use aluminum sulfate (sulphate) to acidify my soil?

Aluminum sulfate acidifies the soil because of the sulfate, not the aluminum. Actually, its possible aluminum, being Al+++, could take the place of 3 hydrogen ions (H+), though more likely is it would take the place of a Ca++ and 1 H+. Anyway, its the sulfate which causes acidity. SO4 + 2 H2O = 2 H2SO4 + O2. Sulfate + water = sulfuric acid + oxygen
