Dipotassium Sulfate

Dipotassium sulfate can be used in water purification. The addition of potassium sulfate is what causes unwanted particles to stick together and form larger and heavier particles that can be removed during the process of water purification.

Note: The FDA highlights that aluminum may be found in many foods at varying levels, and the organization also reports that potassium sulfate may be safe if taken in accordance with recognized limits related to body weight.
