How to grasp the amount of salt added in the sodium ion exchanger

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).

Dosage and regeneration cycle. Obviously, if the raw water has a high content of calcium and magnesium ions and a high salt content, it is not economical to use a sodium ion exchanger.

An extreme example: seawater has a very high salinity content and it is not practical to pretreat it with ion exchange. Seawater desalination reverse osmosis membranes are usually used.

and antiscalants, and use a low ** rate.

to reduce the risk of fouling on the surface of reverse osmosis membranes.

After years of use, the effect of antiscalants is relatively stable, foreign brands of antiscalants are relatively expensive, generally concentrated, when inquiring about the price to ask how many times concentrated. There are different types of scale inhibitors and their uses are different. Reverse osmosis membrane manufacturers also usually recommend some brands of antiscalants to ensure compatibility with membranes.

The antiscalant also has a calculation software, and the recommended dosage of the antiscalant can be known by entering the raw water quality, membrane arrangement and rate. Generally speaking, the calculation is based on the non-fouling of the concentrated water side of the terminal membrane.

My suggestion is that if the salt content is high, in addition to adding the appropriate dose of antiscalant, reducing the rate of reverse osmosis system is also an important means of extending the life of the membrane. In some cases, the problem of the reverse osmosis system is not because the scale inhibitor is ineffective, but because the reverse osmosis system is designed with a small number of membranes and the first rate is set too high in order to reduce costs, resulting in overload operation of the reverse osmosis membrane and damage.

Here's a chemical formula, industrial salts.

The chemical name is: sodium chloride.

The element we need to replace is sodium.

Sodium and calcium substitution.

Calcium CA is 2+ valence.

Sodium Na is 1+ valence.

If you can't replace it, you have to double the amount of sodium.

Ca is 40 atomic weight.

Na is 23 atomic weight.

2 times the Na is 46 atomic weight.

Then this is the time to carry out the replacement.

The atomic weight of sodium chloride is twice as much as the atomic weight of 117.

Then the regeneration level is 117mg m??

117 mg of sodium chloride is required per cubic meter of resin.

Hello dear, how to master the amount of salt added to the sodium ion exchanger There is a formula for adding salt in use, just add it according to this formula. The scientific name of salinization is: sodium chloride, the element we need to replace is sodium ion.

Sodium ion and calcium ion phase replacement calcium Ca is 2 + valence sodium Na is 1 + valence can not be replaced in the type only to double the amount of sodium Ca is 40 atomic weight, Na is 23 atomic weight, 2 times Na is 46 atomic weight, then at this time you can replace the atomic weight of sodium chloride is, twice the atomic weight of 117, then the regeneration level is 117mg m, 117mg of sodium chloride is required per cubic meter of resin.

Summary. Hello dear I am honored to answer for you the sodium ion exchanger, can it process brine Dear, yes. For the treatment of brine, it is necessary to look at the type and concentration of salts in the brine, as well as the type and specification of the sodium ion exchanger.

If the brine contains sodium chloride (NaCl), the sodium ion exchanger can treat the brine because it is able to exchange the sodium ions with the calcium and magnesium ions in the water, and discharge the wastewater containing hard substances such as calcium chloride and magnesium chloride. However, if the brine contains other salts, such as sulfates, carbonates, iron, manganese, etc., the sodium ion exchanger may not be suitable for treating such brine. This is because the ions produced by these salts in water are not sodium ions themselves, so the use of sodium ion exchangers does not remove the hardness.

Therefore, when treating brine, it is necessary to choose different water treatment equipment or processes according to the actual situation to achieve the best treatment effect. Thank you for your patience, delay your time, thank you for your praise and praise for order management! Finally, I wish you a happy life!

Sodium ion exchanger, can it process brine.

Hello dear I am honored to answer for you the sodium ion exchanger, can it process brine Dear, yes. For the treatment of brine, it is necessary to look at the type and concentration of salts in the brine, and the type and specification of the group and sodium ion exchanger. If the brine contains sodium chloride (NaCl), the sodium ion exchanger can treat the brine because it is able to exchange the sodium ions with the calcium and magnesium ions in the water, and discharge the wastewater containing hard substances such as calcium chloride and magnesium chloride.

However, if the brine contains other salts, such as sulfates, carbonates, iron, manganese, etc., the sodium ion exchanger may not be suitable for the treatment of such brine. This is because the ions produced by these salts in water are not sodium ions themselves, so the use of a sodium ion cross-commuter cannot remove the hardness. Therefore, when treating brine, it is necessary to choose different water treatment equipment or processes according to the actual situation to achieve the best treatment effect.

Seaside dwellers, who have no running water, use well water, and use sodium ion exchangers to treat water, can they drink it?

Dear, yes. The use of sodium ion exchangers to treat well water is a common method of treating well water, which can remove hardness substances (such as calcium and magnesium ions) and some heavy metals in the water, making the water softer and more suitable for drinking. If the quality of the well water has reached the local health standards, then the water treated with a sodium ion exchanger can be used with confidence.

In general, the use of sodium flux exchangers to treat well water has become a relatively common way to treat water in the home. It is drinkable.

Summary. The sodium ion exchanger, that is, the softener, is an ion exchanger used to remove calcium ions and magnesium ions in water to prepare softened water. The calcium and magnesium ions that make up the hardness of the water are exchanged with the ion exchange resin in the softener, and the calcium and magnesium ions in the water are exchanged by sodium ions, so that carbonate scale and sulfate scale are not easy to form in the water, so as to obtain softened water.

So how to grasp the amount of salt added in use?

The sodium-ion residual exchange differential roller, that is, the softener, is an ion exchanger used to remove the head of water and neutralize calcium ions and magnesium ions to prepare softened water. The calcium and magnesium ions that make up the hardness of the water are exchanged with the ion exchange resin in the softener, and the calcium and magnesium ions in the water are exchanged by sodium ions, so that carbonate scale and sulfate scale are not easy to form in the water, so as to obtain softened water. So how to grasp the amount of salt added in use?

There is a formula for adding salt in use, just add according to this formula. The chemical name of industrial salt is: sodium chloride, and the element we need to replace is sodium ion.

Sodium ion and calcium ion phase replacement calcium ca is 2 + valence sodium na is 1 + valence can not be replaced, the amount of sodium has to be doubled, ca is 40 atomic weight, na, 23 atomic weight, 2 times na, is 46 atomic weight, then at this time, you can set the vertical change of chlorine orange sodium atomic weight is, twice the atomic weight of 117, then the regeneration level is 117mg m, each cubic meter of resin needs 117mg of sodium chloride.

Summary. How often should the salt tank of the sodium ion exchanger be cleaned? Dear, the salt box should be cleaned regularly every three months.

Manual regeneration operation: 1Backwash:

10-15 minutes; Cleaning method: when there are more stolen goods in the tank and need to be cleaned, the salt should be used in the peep hole can not see the solid salt for 2 3 hours, when cleaning, even the bottom of the tank sewage valve to open the water, take out the filter screen in the tank, use tap water, plastic pipe inserted into the salt hole for washing, after washing, put in the flat filter screen, close the sewage valve.

How often should the salt tank of the sodium ion exchanger be cleaned? How much salt is appropriate to add at one time.

How often should the salt tank of the sodium ion exchanger be cleaned? Dear, the salt box should be cleaned regularly every three months. Manual regeneration of regeneration operations:

1.Backwash: 10-15 minutes; Cleaning Method:

When the tank has more stolen goods and needs to be cleaned, the salt should be used in the peep hole to see the solid salt 2 3 hours later, cleaning will, even the bottom of the tank sewage valve open water, take out the tank filter, with tap water, plastic pipe inserted into the salt hole for washing, after washing, put in the flat filter, close the sewage valve.

As long as the salt is kept continuous, there is no requirement for the amount of salt, but in order to control it, the general salt amount is about two-thirds of the salt tank, and then keep the salt tank full of water. Salt loading steps: when the salt in the salt tank is used to peep hole 1 2, the bucket of nuclear jujube should be loaded with salt, the salt should be loaded with salt after the salt inlet cycle to close the salt tank inlet valve or shut down, when loading salt, with the water release valve after the water does not come out, close the sewage valve and the water discharge valve, and then add salt, after the salt is filled, open the salt tank inlet valve, fill the tank with water and cover, and press the cover tightly after the gas is released, that is, the eggplant can be used normally.

There are three ways to reduce the salt consumption of sodium ion exchanger; The first is the use of soft water-soluble salt, because the chloride ion content in soft water is low, so the salt dissolution speed is relatively slow. The second is the use of two-stage softening, because the two-stage softening increases the periodic water production (working exchange capacity) of the system equipment, which naturally saves the amount of salt used for equipment regeneration and reduction. Third, the selection of countercurrent regeneration process equipment is the foundation of salt saving in the overall system. Yijie water quality.

In the case of complete replacement, the salt absorption time can be shortened, and this is the only way to do so.
