Water treatment chemicals - Lenntech

In order to neutralize acids and basics we use either sodium hydroxide solution (NaOH), calcium carbonate, or lime suspension (Ca(OH) 2) to increase pH levels. We use diluted sulphuric acid (H 2 SO 4) or diluted hydrochloric acid (HCl) to decline pH levels. The dose of neutralizing agents depends upon the pH of the water in a reaction basin.
