Granular activated carbon filters are primarily used to?

Granular activated carbon filters are primarily effective in removing organic contaminants, chlorine, and other unwanted substances from water, making them a common choice in the treatment process for water used in soft drinks and bottled drinking water. These filters work through adsorption, where the surface area of the activated carbon captures impurities, leading to improved taste and quality of the final product.

While granular activated carbon can play a minor role in removing some contaminants that may overlap with heavy metals, it is not designed specifically for heavy metal removal, which often requires other treatment methods such as ion exchange or reverse osmosis. Furthermore, the filters do not alter water pH levels significantly, nor do they have any impact on reducing water temperature. Therefore, their main application in treating water for beverages underscores their importance in ensuring the safety and quality of the water used in consumer products.
