Sowinter water purification device – American. Price requested: 2500 Hard water is produced by the proliferation of calcium and magnesium salts in water. The water purification device works by replacing the salts that cause water hardness with other harmless salts. Features 1. Maintenance of the home plumbing system (pipes, faucets, water heaters) to prevent clogging due to calcium deposits. 2. Helps in getting rid of dry skin problems. 3. Helps in solving dandruff and hair loss problems. 4. Saves cleaning materials used in home cleaning processes. 5. Saves energy for electrical appliances. 6. Maintenance of dishwashers and washing machines. 7. Maintains the quality and colors of clothes. Note: Make sure to refill the salt periodically based on consumption and water quality. Mechanism of operation of the water purification device: 1. Untreated water passes through resin granules inside the device. 2. The resin is charged with negatively charged sodium ions. 3. Calcium and magnesium salts are positively charged cations. 4. Positive charges (calcium and magnesium) are attracted to the resin and adhere to its surface. 5. The resulting water is free of elements causing water hardness and is distributed throughout the home's plumbing system. 6
