Alkaline water purifiers increase the pH level of water, typically to a range of 8 to 9, using a multi-stage process. Here's a breakdown:
The Process of Making Alkaline Water
The creation of alkaline water in a water purifier generally involves these key steps:
-
Initial Filtration: The water first passes through a sediment filter and a carbon filter. These filters remove larger particles like dirt, rust, and sand, as well as chlorine, volatile organic compounds (VOCs), and other contaminants that affect taste and odor. This ensures the water is clean before the alkalization process.
-
Alkaline Mineral Addition: This is the core step. The water then flows through an alkaline filter or cartridge. This filter contains alkaline minerals such as:
- Calcium: Contributes to bone health and other bodily functions.
- Magnesium: Important for muscle and nerve function, blood sugar control, and blood pressure regulation.
- Potassium: Helps regulate fluid balance, muscle contractions, and nerve signals.
The filter media, which may be mineral stones (like those containing magnesium oxide) or calcite (calcium carbonate), releases these minerals into the water. This increases the pH level, making the water more alkaline.
-
Ionization (Optional): Some alkaline water purifiers also use ionization. This process involves electrolysis, where an electric current separates the water into acidic and alkaline streams. The alkaline stream is then collected for drinking. It's important to note that the scientific basis for the health benefits of ionized alkaline water is still debated.
-
Secondary Filtration (Optional): Some systems include additional filtration stages after the alkalization process to further refine the water and remove any remaining impurities.
Key Components and Their Functions:
| Component | Function |
|---|---|
| Sediment Filter | Removes dirt, rust, and other suspended particles. |
| Carbon Filter | Removes chlorine, VOCs, and improves taste and odor. |
| Alkaline Filter | Adds alkaline minerals (calcium, magnesium, potassium) to increase pH. |
| Ionizer (Optional) | Uses electrolysis to separate water into acidic and alkaline streams. |
Summary
In essence, an alkaline water purifier cleans the water through standard filtration and then increases its pH by adding alkaline minerals. Some models also use ionization. This results in filtered water with a higher pH level, which some people believe offers various health benefits. However, it's essential to consult with a healthcare professional to determine if alkaline water is right for you, as its benefits are still being studied.
