Both the acidic and basic reverse infiltration cleaners could be dissolved in water and absorbed on the crystallites of the mineral salt to increase the repulsion of the particles and prevent or reduce the formation of scale. However, there were differences between the two in the following aspects: 1. ** Water source **: Acid reverse infiltration cleaning agent is generally used for underground water, tap water, well water, etc. Alkaline reverse infiltration cleaning agent is generally used for surface water, seawater desalination, river water, lake water, etc. 2. ** Coping with the tendency to scale **: If the raw water has the tendency to scale with calcium carbonite, the PH value of the water into the reverse infiltration equipment should be adjusted to acidic. At this time, acidic cleaning agents should be used. If the basic cleaning agent is used, the reaction of calcium carbonite will be aggravated, resulting in more serious equipment scaling. 3. ** Microorganism content **: When the amount of microorganisms in the surface water is not large, there is no need to use an alkali-based cleaning agent; when the amount of microorganisms is high, it is recommended to use an alkali-based cleaning agent because it has a germicidal and suppressive effect. 4. ** Dirt removal type **: Dirt can be divided into acidic and basic. Alkaline dirt is more common. Acid cleaners can remove dirt and adjust the PH value through neutralizing reaction, while basic cleaners can remove acidic dirt. The fundamental reason was that the acid and base substances in the device needed a corresponding acid and base level to undergo a chemical reaction. 5. ** applicable pollution type **: Acid washing is mainly applicable to the pollution of the membrane surface, and the basic washing is mainly applicable to the pollution caused by ion pollution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
