How Do Pelembut Air Systems Work?

Have you ever tasted your drinking water at Rumah? 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.

Semasa anda melihat sekeliling rumah anda, perhatikan tanda-tanda biasa air keras ini: kerak atau sedimen seperti mineral yang terkumpul di sekeliling kepala pancuran mandian atau paip, bintik-bintik air pada pinggan mangkuk selepas mencucinya, pakaian kaku atau bernoda kelabu selepas mencucinya melalui pakaian, dan kulit kering yang merengsa selepas mandi.
 

Walau bagaimanapun, cara yang paling boleh dipercayai untuk menentukan sama ada rumah anda mempunyai air keras atau tidak ialah membawa sampel air ke makmal ujian air yang diperakui.

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.
