A METHOD FOR ITS REGENERATION This invention is a network used for cleaning items such as laundry or tableware. an ion exchanger that softens the water before sending it to the washing compartment 5 shortening the time required for resin regeneration and thus reducing energy consumption. a household appliance that enables reduction and ion reduction to be carried out in said household appliance It relates to a method for regenerating modifier resin. The washing performance of washing and washer-dryer devices in technology is determined by many parameters. It is also affected by the hardness level of the tap water. The ions that cause water hardness are 10 It neutralizes the active ingredients in detergents, reducing washing performance. These ions can also accumulate in the fabric of clothing, causing the colors to fade. This is why. Using hard water causes limescale buildup in different components of the appliance and Therefore, this leads to an increase in energy consumption. This situation affects the components. It also shortens their usage times. The desired washing performance in washing systems is 15. To ensure and prolong the lifespan of systems, the use of softened water is important in technology. It is currently a preferred practice. Nowadays, salt is used for regeneration for this purpose. The use of ion exchange resins is common. These systems utilize ion exchange resins and... It consists of two main components, including salt. Water taken from the network passes through the resin. The ions that cause hardness in the water (Ca+2 / Mg+2) pass through the sodium (Na+) ions present in the resin. It is replaced by a scrubber containing softened water rich in sodium ions. The washing is done by feeding the system. In order for these resins used in technology to retain their water softening properties, the mains water must be treated. Depending on its hardness, at the end of each softening cycle or as determined by the user / manufacturer. The ion exchange resin is regenerated periodically. With sodium ions, 25 Since calcium and magnesium ions are exchanged, sodium plays a role in resin regeneration. chloride salt is used. In the regeneration step, the resin is supersaturated with sodium chloride. It is washed with a solution. Sodium ions bind to the resin, while calcium-magnesium The ions are passing into the water. The water, which is rich in calcium and magnesium ions, is being discharged. The resin, which has transformed into a sodium ion-rich structure, is ready for reuse. 30 2 is brought in.

In the system, there is a first arm that feeds the first tank and a second arm that feeds the first tank. a water supply line and a contract that will branch off to a second branch going to the tank's inlet opening. The subject is a primary electric valve 10 to control water flow along the supply line. This is ensured. The flow of water going to and passing through the second tank is controlled by an electric valve. It is controlled by the system. The system also handles dishwashing and regeneration. Adapted units for generating saltwater and determining the amounts of water used. These are supported by an electronic control unit that monitors them. However, in systems where regeneration is carried out with salt water, the saline solution used is 15 This necessitates the removal of water from the system. This discharge process affects both the infrastructure. It causes corrosion and also leads to the salinization of soil and water resources. During the loading of salt into the scrubber system for the regeneration step... Spilled and uncleaned salt particles also pose a corrosion risk.
