How Do Chất làm mềm nước Systems Work?

Have you ever tasted your drinking water at nhà? Usually, your tap water  is not as clean as you think and leads to bad tasting hard water (hardness minerals and contaminants) from your local water supply. Water hardness is based on the concentration of hard minerals, such as calcium, magnesium, and manganese in the water. “Soft water” has a very low concentration of hard minerals, while “very hard water” has a relatively high concentration of hard minerals. Using hard water can cause mineral buildup inside of your water-using appliances which can lead to long-term damage.

Khi bạn nhìn xung quanh nhà, hãy tìm kiếm các dấu hiệu phổ biến của nước cứng: lớp vỏ hoặc cặn giống như khoáng chất tích tụ xung quanh vòi hoa sen hoặc vòi nước, các đốm nước trên bát đĩa sau khi rửa, quần áo cứng hoặc dính màu xám sau khi giặt qua và khô da bị kích ứng sau khi tắm.

Tuy nhiên, cách đáng tin cậy nhất để xác định xem nhà bạn có nước cứng hay không là mang mẫu nước đến phòng thí nghiệm kiểm tra nước được chứng nhận.

Acting as a water filter, water softening systems “soften” the hard water by removing mineral ions, such as manganese or calcium, through a process named ion exchange. This process consists of exchanging positively charged mineral ions in the hard water with positively charged ions, leaving the softened water free of mineral ions. There are two tanks in a water softener system that facilitate this ion exchange, the resin tank (aka mineral tank) and the brine softener tank. The resin tank does the bulk of the water softening as the sodium ions from the brine solution exchange places with the mineral ions (water hardness ions). Ion exchange resin beads and water combine resulting in the hardness minerals attaching to the beads. Once all of the resin beads have been covered in hardness minerals, they are flushed out of the tank using either potassium chloride or sodium chloride. The water exiting the resin tank contains a very small number of sodium ions, but no longer contains high levels of hard mineral ions. Through the control valve, the brine tank then recharges the resin tank through a flushing process where the resin tank is rinsed with salt water from the brine tank. The salt water saturates the resin bead, removing any stuck mineral ions and replacing them with a sodium ion. The dissolved minerals are then flushed and the system is ready to soften water again.
