A pH adjustment or correction of the acidity of water is important to obtain a good physical-chemical reaction.
A pH correction can be done by adding acid (pH decrease) and / or bases (pH increase).
Herefore usually inorganic acids such as H2SO4 (sulfuric acid =) and HCl (hydrochloric acid =) and inorganic bases are used as Ca (OH) 2 (= lime) and NaOH (lye =)
For specific applications, acidification by mixing CO2 gas in the water is a very interesting technique.
Over the years AAQUA NV has obtained a great expertise in this matter in both the food and the chemicals sector.
In order to execute a proper pH correction the pH level first has to be measured with a pH probe and an associated converter.
This converter controls an acid- or base dosing pump. The dosing volume is automatically determined in order to obtain the desired pH.
By the means of dosing pumps liquid chemicals are added according to the desired concentration. The most common dosing pumps are:
