What type of pollutants can be effectively removed using ion exchange methods in drinking water treatment?

Ion exchange methods are particularly effective in removing a variety of pollutants from drinking water, including heavy metals, chlorides, and fluorides. The process relies on the exchange of ions in water with ions that are attached to a resin.

Heavy metals, such as lead and cadmium, can be removed through this process as the ion exchange resins effectively capture these undesirable metallic ions from the water. This makes water safer for consumption by reducing potential toxicity from these metals.

Chlorides, which can contribute to salty taste and can corrode pipes, are also effectively removed through ion exchange. The resin exchanges chloride ions for other less harmful ions, effectively lowering chloride concentration in the treated water.

Fluorides, often added to water supplies for dental health but present in potentially harmful levels, can also be removed using ion exchange techniques. The resin is selective and can specifically target fluoride ions, enhancing limits to safe drinking water levels.

Since ion exchange is versatile and effective for all these types of pollutants, the best answer encompasses all options, indicating that ion exchange methods in drinking water treatment can indeed remove heavy metals, chlorides, and fluorides.
