Salt tank for water purification systems. Salt tanks. Device and principle of operation Instructions for backfilling salts in the salt tank

It is such an important node as a salt tank. It would seem that the simple container was covered with salt and everything that questions could still be. In practice it turns out that there are many questions. We will try to answer this article to the most popular of them.

1. How is the salt tank arranged?
Salt tanks are of different shapes and different size. For each sizer of the cleaning system, its salt tank sizer is recommended. The table below shows the main sizes of salt tanks used on household and small industrial facilities and their characteristics.

Inside the bottom of the tank there is a so-called false bottom with perforation. It relies on snap-on cups, and one of inland walls The tank is fixed (it is also called mine) with a skeletal mechanism inside. This mine goes along the entire length of the tank from above to the bottom, passes the feet and goes until the bottom of the tank. So it works almost any salt tank of any size. Now more, what for which it serves.
False bottom divides the tank into two parts. Under false bottom, salt tablets do not fall and there is a ready-made concentrated brine. What does it give? Without false bottom, the amount of available brine would be less - this is only a few liters of fluid, which is distributed in the free space between the tablets. And the less tablets become, the smaller this space and, accordingly, less brine. If the filter cylinder system small size, you can do without a false bottom. Installation of softening in 8x44, 10x35, 10x44 with 70 liter salt tanks will be sufficiently brine, which is formed in the free space between the tablets. Systems with a cylinder 10x54 and a more salt tank must be used with false house otherwise the system will not work on full power. False bottom contains "untouchable" stock, allowing the desired volume of salt to dissolve in the desired volume of water. The larger the size of the system, the greater the size of the tank used and the greater the amount of space under false bottom.
The second important node in the saline tank is a soletoryal mechanism (sterling valve), which is in a mine inside the tank. It is a special valve that performs two functions:
The first is during the replenishment of the tank with water using a float switch (as in the toilet) it stops the flow of water into the tank. The float can be adjusted upwards by defining the amount of water in the tank, depending on the need for a specific system size. Also, the float will force from flooding if electricity and the valve of the control unit will stand in the "filling of the brine" at the time of replenishment of the tank.
The second - during regeneration during the suction of the brine, the ball valve at the bottom of the mechanism drops with a drop in the level of the brine and thus stops the absorption of the air inside the system of the system.

2. How to assemble the salt tank correctly?
It is easy enough to do, perform the following steps.
1. Cups are riveted to False,
2. False falls into the tank until it becomes for the cups,
3. Mine is inserted into the hole in the false day in its place,
4. In the wall of the tank at the desired level, the hole for entering the tube - the salt line is drilled,
5. The salt line from the control unit is connected to the skeletal valve through the fitting, while the piston is inserted into the tube,
6. The mine cover is closed and the salt tank lid.

3. How to configure the salt tank correctly? How many salts need to wash and how much to fall asleep to the tank?
Salt tank setting is proper installation Tank replenishment time in the system control unit and correctly setting the level of the float switch inside the mine.
To do this, we need to know how many liters of the filter material on your system. The normal regeneration of one liter of ion exchange resin requires 120 grams of salt. Accordingly, for example, for a cylinder system 1054 with a loading rate of a resin 38-40 liters, 4.5 salts are needed per flushing. The solubility limit of salt in cold admissible water is 300 grams per 1 liter of water. Accordingly, in order to dissolve 4.5 kg of salts you need 15 liters of water. In the control unit, the time of the water tank is set to the tank, sufficient for a set of 15 liters over false bottom. Next, we fall asleep into the tank salt until the water level is equal to the salt level. This will be the level of installation of the float switch. And therefore it doesn't matter that 25-30 kg of salt can be in the tank. If everything is adjusted correctly, then more than you need salt on one regeneration will not be spent.
So!

Number of salt on regeneration, kg \u003d number of resins, liters x 0.12 kg / liter

The amount of water in the tank, l \u003d the required amount of salt, kg / 0.3

4. How much salts can be filled into the reserve tank?
Depending on the quality and amount of fluid consumed, the system will produce regeneration with a greater or less frequency. If the rigidity is high (for example, 6 mM-eq. / Dm3), and the system is small (1044 - 30 liters of loading), it should be washed every 5 m3 and consuming 3.6 kg on flushing. Salt. When consumed 20 m3 of water, 15 kg will be spent a month. With this consumption, you can fall asleep in a 70 liter tank 40-50 kg and shove as needed. And if the rigidity is average (4 mM-eq. / Dm3), the system 1252 per 50 liters of cation is the regeneration will take place every 12.5 m3, and consume 6 kg. Salt. At the expense of the same 20 m3, it will be no more than 12 kg. And thus due to different source hardness big system Consumes less salt per month than small with the same water collection. In this situation, no more than 30 kg is better to refline for the system 1252. Salt. Thus, the more often the regeneration occurs, the more you can pour about the reserve.

5. Why water (salt) does not leave the tank?
The large volume of salt in a tank with rare flushing can cause the effect of the peel - small semi-solid pills, which are in water are crushed under the weight of the layer of 50 and more kg and turn into a salty cascore. This "porridge" is lingered and the system after a while cannot prepare the correct saline solution, because water almost does not pass through the layer of the slave salt. In the investigation of this, the system first cleans the water well, and after a few cubes the quality deteriorates. All because regeneration passed with an insufficient amount of brine. There may be other reasons, more about it

6. How in the end it all works?
When you first start from the filter automation, water enters the tank. Sometimes you can pour manually. Next to the tank will fall asleep salt. After 2-3 hours, the brine is ready for use. But it will not be used immediately. Automatic block control tracks how much water passed through the filter and at the end of the resource will prescribe the regeneration of the system. During flushing, the automation will turn on the "drink" mode and thanks to the embedded ejector over the salt line from the tank to the system will arrive. At the end of the washing, the control unit itself will reach the desired amount of water to prepare the brine next time.

Completed with a tank - a special capacity for the preparation and storage of the regenerating solution. The regenerating solution (regenerant) is used to restore the filtering properties of the filter loading properties. The tank may have a different form (for example, barrel-shaped (see Fig.) Or a square section and size - depending on the type of regenerant used and the filter performance, with which the tank will be used.

Thus, the tank is a certain container (1) (usually plastic) with a lid (2). In some models in the tank, a special mesh (3) is installed, on which the regenerant is poured (7), it is missing in others, since without it, in principle, you can do.

The most important node is mine (4), which is a plastic tube with an orange-mounted suction system. The composition of this system includes a float locking valve (5) and ball shut-off valve (6) (Air-Checkvalve). A suction system through the fitting (9) is connected to.

For insurance (in the event of a refusal of all systems for adjusting the amount of water in the tank), an overflow unit is established (10), which, ideally, must be connected to the drainage line.

Principle of operation

1. Getting started

A certain amount of water (8) is poured from the filter to the tank (the first fill of water in some models is carried out manually). Next to the tank, the chemical regenerant (7) is falling asleep (7), for example, potassium permanganate (manganese) for or tableted patient salt for. Adjusting the amount of water supplied is made by either the corresponding setting of the float valve (5), or the automatic filter control unit (float valve in this case - additional protection against overflow). The amount of water is determined by the type of filter and its capacity, while the water level must be several centimeters to exceed the grid level (3), if available.

It is obvious the importance of filling the tank for the regenerating solution is strictly calculated, and not an arbitrary amount of water. So the regeneration of 1 liter of resin in an ion exchange softener requires a completely definite amount of table salt (NaCl). To dissolve the table salt having a solubility limit of about 300 g / l, a certain amount of water is required. It means that water should be exactly so much to dissolve such a number of tablet salt, which is necessary for the full regeneration of this filter. In a smaller amount of water, less salt will dissolve, which will not allow the resin to be restored to a sufficient degree of ion-exchange capacity and entail a decrease in softening efficiency and. IN larger quantities Water regeneration resin will be even better, but salt consumption for each regeneration will increase, and maintenance costs will increase.

There should be enough time between regenerations so that a concentrated solution of the regenerant is formed in the tank. At first glance, it seems that the rational use of salt of the axes, and not in the form of tablets (cheaper, dissolves faster). But the use of salt is in pressed form not by chance. Moreover, not only tablets are used, but also salt briquettes that have a shape of pads or capsules, as well as a compressed tablet salt, crumbling into pieces of several centimeters (like a crushed stone).

Practice has shown that salt in the water is very quickly joining the monolithic com. Such a com that has a significantly smaller surface area than the amount of salt in tablets in weight, is much slower dissolved. At the same time, it increases around the mine (4) with a suction system, which completely blocks the operation of the filter regeneration system, it is inevitable thereby deriving it out of order.

2. Regeneration

During the regeneration cycle, a solution from the tank begins to the filter control unit (through a suction system). There is a dilution of the regenerating solution with water in a certain proportion. Next, the finished solution is used in the process of chemical regeneration.

The level of the regenerating mortar in the tank is reduced as it sues. The level decrease occurs until the ball shut-off valve is triggered (6) when the ball is tightly sitting in the saddle and overlaps the flow. This allows you to stop entering the air in a suction line.

3. Filling water

Upon completion of the filter regeneration, water is supplied from the filter control unit. The flow of water occurs through the same suction line, only in the opposite direction - through the fitting (9) and the shut-off valve (6). The cessation of water supply is made either by the filter control unit command, or when the float valve is triggered (5). Over time, in this water, the desired amount of salt dissolves and the process is repeated under the next regeneration.

The undoubted advantages of this system are its simplicity and reliability.

Selection of saline tank

Salt tanks (feeders) intendedfor the preparation and storage of the solution of the cook salt, which need to restore properties Filtering layer softeners. Depending on the number of downloads, productivity of the system and the volume of salt spending on regeneration, type and size of the feeder used may be different. Such salt tanks are made from dense polyethylene, what guarantees good jobequipment in the composition of water treatment systems for a long time.

Salt Baka design

The feeder for the regenerating solution is one of the component cleaning systems. Standard salt tank is case with cast lid and consists of a fence mechanism, the bottom lattice and the well.

One of the most important nodes is the mine - plastic trumpet. The suction system mounted inside it includes a fitting for connecting the feeder with a softener control unit, a ball cut-off and float locking valves.

There is also an overfitwhich connects to the drain line and installed in caseIf all the system for adjusting the amount of water in the feeder fail.

What kind of salt tank buy?

To properly choose a salt tank, you need to take into account important characteristics Products. These include water flow, the amount of download and the size of the column. The price of the salt tank depends on the size, configuration and shape of the structure. If necessary

In the process of mitigating water rigidity, many substitution reactions occur. Most often in the liquid there are positive calcium and magnesium ions, which need to be replaced by negatively charged sodium particles. This procedure increases the service life of all connected techniques, but ion exchange boots cannot cope with the task without regeneration.

Salt tanks are included in the design of systems with reagents for water purification. Such equipment is necessary for softening liquid or complex filtering of contaminated raw materials. Tanks play a huge role in cleaners, as they contribute to the regeneration of cartridges, which increases their life. The tanks are refilled by the cooking salt, which consists of their sodium chloride. When interacting with water, the molecules are split, work on the substitution, do not leave the sediment and save appliances from scale. In most models, the process of recovery of the cartridge occurs automatically from the control valve, the user must monitor the salt level - on this presence in the process ends.

How to choose a salt tank

Externally, the design looks surprisingly simple - no more difficult to the garbage basket, but internal organization Includes a mortar mine, and a plurality of valves, and a lattice for reagents. In each model, different equipment is complicated, which complicates the selection for ordinary users.

1. Water consumption.
2. Number of download.
3. Column size.
4. Form, color.

All this should take into account when buying, but it is quite difficult to make calculation. In order not to overload you with superfluous formulas and problems, we take this task for yourself. It is enough for you to contact our company by phone or mail, and managers themselves will select the necessary configuration, taking into account your wishes and call back to report ready decision. With all this, you only pay for the salt tank.

To ensure the normal performance of the filter-softener, as well as for the convenience of a user who has acquired a system of softening with automation, it is necessary to have a sufficient reserve of the finished saline. The storage function of the finished reagent performs a saline tank, which is an integral part of the water treatment system. The salt tank is embedded in the water treatment system, by means of saline, it is connected to the filter and at the time of the regeneration, the suction system takes the necessary amount of solution from the tank, dilutes it with water and washes the filter.

The salt tank for regeneration should be filled into strict accordance with the instruction, since it requires a certain amount of water and a reagent for the effective regeneration of the entire filter material. "Challenge" and the actions "on the eyes" are unacceptable here. The decrease in the amount of water and the reagent will lead to an incomplete process of regeneration deterioration of water quality at the outlet, which means the flushing will have to repeat after a shorter period of time, which leads to additional costs. Excessive amount of salt and water will increase the efficiency of regeneration, but will also lead to an increase in operating costs.

That is why when buying a cleansing equipment, no less attention is required to give the selection of additional components. Pick up and buy salt tank for softener will help you experienced and qualified company managers.

In the range of our catalog presents salt tanks 25 liters, 70 l, 72 liters, 100 liters, 140 liters, which have the following features:

• made of durable plastic, not subject to corrosion and non-peculiar with brine;
• there may be a cylindrical shape or square section, you can choose that construction that is convenient for you;
• they have a special grid, which is poured with a tablet salt. The lattice contributes to the preparation of a better solution, because prevents the stroke of the material.
• some models have an overclocking fitting, which insures the water level control system in case of its failure;

The salt tank is connected to the filter-softener filter control valve. autonomous work without user participation. When buying a softener with an automatic control valve, the person's participation in the operation of the softening and regeneration system is reduced only to the timely replenishment of reagent reserves.
