What is the primary function of a water softener?

The primary function of a water softener is to soften hard water by removing magnesium and calcium ions. Hard water is characterized by its high content of these minerals, which can lead to scale buildup in plumbing and appliances, reducing their efficiency and lifespan. By using a water softener, sodium ions are typically exchanged for the hardness ions (calcium and magnesium) present in the water. This process not only improves the quality of water for household use but also enhances the effectiveness of soaps and detergents, leading to better cleaning results.

This function is critical, especially in settings like dialysis, where water quality is paramount to patient safety and equipment performance. By ensuring that the water used in the dialysis process is free from high levels of hardness, the risk of complications and damage to the machinery is minimized.
