The most important use of carbon filter is to remove chlorine from water.

the biggest factor that negatively affects the ozone system are the humidity and heat of the air. that the role of humidity is much more destructive. Therefore, in big projects, it is recommended to use an air conditioner to dry and cool the air.

A) Backwash: In this stage, water enters from the bottom of the softener tank under pressure and exits from the top of the tank. This process of water is contrary to the usual direction of water entering the tank and causes the compressed resins to separate from each other so that in the next steps the entire surface of the resin is in contact with the incoming salt water.

1. B) Salt water suction: At this stage, saturated salt water is sucked from inside the salt container and enters from the upper part of the softener tank, and after passing the entire height of the resin, it is transfer from the lower part of the tank. During this process, calcium and magnesium absorbed by the resin are separated from it and replaced with sodium in the salt water, and leave the system along with the permeate water.
2. C) Filling the salt water tank: It is obvious that the salt water tank needs to be refilled after emptying, this is done by the same suction hose.

1. D) Sodium washing: In this step, the water passes through the resin column from the top of the softener, dissolves the remaining salt in it, and is discharged through the waste path. note that this step is especially important where this water is used as drinking water. If this step is not done completely for any reason, the output water will be salty and, in some cases, it will cause digestive problems in the consumer.
2. E) Production: hard water entered from the top of the tank after passing through the calcium and magnesium resin layers changed and the soft water leaves the system.

After replacing the calcium and magnesium in the water with sodium, the resin accumulates calcium and magnesium and no longer has sodium in it to perform the replacement action. For this reason, it is necessary to regenerate the resin before reaching to saturation stage.

The resin in the softener holds these ions for some time. Until the system regeneration time arrives (according to the time or output flow rate from the device), these ions are replaced by sodium in the regeneration operation and are removed from the device by the waste hose.

The salty taste is related to the chlorine ion that does not enter the permeate water

As mentioned, sodium ion replaces calcium and magnesium ions in the resin softener, and salt is rich in sodium ions. In fact, the container of salt water that is placed next to the softener and is responsible for supplying the required sodium.

In the resin softener, calcium and magnesium ions, which have a high ability to Sedimentation, are replaced by sodium ions, which have a low ability to Sedimentation.

Most of the time, the smell of water is caused by the decomposition of organic matter, which smells like rotten eggs. In order to remove H₂S produced by anaerobic bacteria, we must either prevent the activity of these bacteria by aeration or destroy them by injecting substances such as chlorine and ozone.

1. A) Filter: In this case, the water passes through the silica layers from the upper part of the tank and finally exits from the lower part of the tank. As a result of passing through the silica layers, turbidity is left in this layer and the clear water is removed from the system.
2. b) Backwash: water enters from the lower part of the tank under pressure and moves the remaining minerals cause turbidity from its place and discharges from the upper part of the tank.
3. c) Fast washing: as in the production stage, water enters from the top of the tank and leaves from the bottom of the tank. This step is done immediately after the backwash step and to ensure that the water becomes clear before sending it for use.
