pH Adjusters for Water Treatment

What is a pH Adjuster for Water Treatment?

A pH adjuster is a chemical used to alter the pH or Potential Hydrogen level.  pH (Potential Hydrogen) is the measurement of the activity of the hydrogen ion or how basic or acidic something is. By adding a pH reagent such as an acid you can drive pH downward. By using a caustic or other alkaline substance you can drive pH upward. Typical pH range is 0-14 but actual pH levels can exceed these theoretical limits.


What chemicals are used to adjust pH?

Anionic, Nonionic and Cationic Gel Logs

Sulfuric acid and sodium hydroxide (caustic) are most commonly used for neutralizing acids or bases. Caution must be used for pH adjust applications as an exothermic reaction will occur generating heat. The more severe the application the more heat generated. For example; pH adjusting tap water will create very little heat and is a non-issue. Neutralizing solutions with a high percentage acidic or bases can generate significant heat and therefore must be considered in design and materials. Use caution when doing any pH adjustment.
