The scope of the problem is too wide, you have to explain clearly what kind of ion exchange equipment, such as yang bed, mixed bed, etc., so that it is convenient.
If it is a yang bed, then following the yin bed can effectively solve the problem, but I think your problem should be more related to the possibility of low water pH of mixed bed equipment, and the normal water pH of mixed bed equipment is **), if you want to increase the pH value of the water output, you can add ammonia or alkali appropriately. This involves what this part of the water is used for. For example, the stator cooling water of the generator set is required to be purified by resin, which can not only control the conductivity but also increase the pH value, and there are three methods commonly used in the domestic generator set, 1. Sodium-type cation resin hydroxide-type anion resin, rinse with a large flow of pure water before use, and flush the conductivity to less than that after putting it into use; 2. Hydrogen-type cation resin Hydrogen-oxygen anion resin is mixed and loaded into a mixed bed, followed by a micro-alkalizing device (that is, a small amount of NaOH is added to adjust the pH value); 3. Sodium-hydrogen mixed cation resin Hydroxide-oxygen anion resin is mixed as a mixed bed resin, which has to be based on the user's different water quality conditions, micro-blending ratio, the general water production pH can be controlled, the conductivity is less than, and then with the extension of the use time, the effluent conductivity gradually increases at the same time, and the pH also increases synchronously.
Since your question is too broad, I can only give examples of the above, if it is not appropriate, you can follow up.

Check the table, or for systemic reasons, dosing is required.

You give too little information about the equipment, is it a yang bed, a yin bed, or a mixed bed out of the water??
Please complete the information and I can help you.

This bend clan divination gives too little.
What is the quality of raw water? Was there a yang bed before? Or is it a buried ear shade bed that goes straight in?
The yin bed replaces the anions in it with oh-, and if it passes through the yang bed first, then the hardness will be very low at the single-digit level.
If it is not passed through the sun bed, then the hardness of the basic spike and the water inlet is the same.

Can be adjusted indirectly. The more thoroughly the exchange, the greater the excess alkalinity of the water, and the pH will rise after the boiler evaporation and concentration. Of course, if the hardness of the sodium ion exchanger has reached the lowest, then the excess alkalinity will not go up anyway, and the pH value can only be adjusted by adding medicine in the pot.

The mixed bed is generally the terminal treatment water of the ion exchange system equipment, also called"Product water", the effluent pH should be in the state of no friend.... The water quality is withered.

If you only exchange it with cationic resin, the water will appear acidic after exchange. However, this is for H+ type cationic resins, and if it is Na+ type, it will not change the acidity and alkalinity of the water. Beijing Huayu Qingyuan International ******, Du Sheng ion exchange resin.
-
Acidic Because the cations in the water are exchanged by H+ on the active group of the resin, H+ enters the effluent and the pH is acidic.
Except, of course, for Na+ resins.

Ion exchange is impossible to produce pure water, and the truly reliable pure water technology is Qingdao's Langyong brand RO reverse osmosis aseptic water purifier.
-
Maybe it wasn't cleaned, but was it before?
-
Because the water outlet of the exchanger cannot be in an acidic state, it has a corrosive effect on the system equipment behind it, affecting the normal operation of the equipment....

The water from the sodium ion exchanger has no effect on the pH value of the water quality. Brilliant water quality.
Personal experience suggests that knowing the divalent ion content of the raw water, the industrial salt required for the sodium ion exchanger can be obtained through the calculation software provided by the ion exchange resin (or by simply converting it yourself). >>>More
1) Water treatment.
Ion exchange resins are in high demand in the water treatment field, accounting for about 90% of the production of ion exchange resins, which are used for the removal of various anions and cations in water. At present, the largest consumption of ion exchange resins is used in the pure water treatment of thermal power plants, followed by atomic energy, semiconductors, electronics industry, etc. >>>More
Due to the rapid development of ultrafiltration membranes and reverse osmosis membranes, ion exchange methods are gradually withdrawing from the market in many fields. >>>More
Macroporous resin is a pore with physical properties, the pores can be through organic macromolecular substances, relying on intermolecular van der Waals force can adsorb organic macromolecular substances, with adsorption effect, but when used as water treatment, because there are no organic macromolecules in the water, or a small amount, but it contains a large amount of electrolytes (that is, salts), ionization is followed by anions and cations, and macroporous resin also has a lot of ion exchange groups, at this time it can exchange ions in the water to achieve the purpose of purifying water, In other words, macroporous resin has adsorption and ion exchange, but it mainly plays an ion exchange role when used for water treatment.
The adsorption chromatography stationary phase is a solid adsorbent that is separated by the difference in the adsorption capacity of each component on the surface of the adsorbent. >>>More
