Caustic soda (sodium hydroxide, or NaOH) is a commonly used water treatment chemical that raises the pH of water by absorbing water and carbon dioxide. Read below to learn how sodium hydroxide can benefit your water treatment plant.
Caustic soda causes saponification and is an essential ingredient in soap-making. When flakes or beads of sodium hydroxide get added to a liquid, it forms a lye solution. This solution, when mixed with oils or fats, will lead to the chemical reaction called saponification.
