There are many kinds of scale inhibitors, which can be divided into acidity and alkalinity according to the pH of the liquid. Both of them can dissolve the fouling and destroy the conditions of fouling. What is the difference between acidity and alkalinity?
There are many kinds of scale inhibitors, which can be divided into acidity and alkalinity according to the pH of the liquid.
Both of them can dissolve the fouling and destroy the conditions of fouling. What is the difference between acidity and
alkalinity?


1. Scale inhibitor is mainly acidic, and alkaline scale inhibitor is a product. The difference between them lies in the different
types of raw water used. Acidity is generally used in groundwater, tap water, well water and so on; alkalinity is generally
used in surface water, seawater desalination, River water, lake water and so on.


2. Acidic scale inhibitor is more widely used because if there is a tendency of calcium carbonate scaling in the raw water of
customers and users, the pH value of the influent of reverse osmosis equipment should be adjusted to control the acidity
and precipitation of calcium carbonate from hydrolysis of bicarbonate-ions, so it is often necessary to add acid to regulate
the scaling of control system in many equipment systems. If alkaline scale inhibitor is used at this time, it will be beneficial
to the reaction of calcium carbonate.


Fouling is also divided into acidic and alkaline, of which alkaline fouling is more. Using alkaline scale inhibitor can not only
remove fouling by neutralization reaction principle, but also adjust the pH value. On the contrary, acidic scale inhibitor
can remove acidic fouling.
