What is the water filter made of?
Activated carbon
This is the most popular domestic water purifier. Its popularity is so high mainly because it is cheap, small and easy to use. The filter uses charcoal based
[u]active carbon[/u] particles to stop contaminants. Charcoal is not very dense, it actually has a porous structure filled with ridges that attract and capture chemicals through adsorption. Adsorption is a process in which gases and liquids are trapped by other liquids or solids.
Distillation
Since we were children, we have been taught that boiling water makes it cleaner. Distillation is a more advanced method of boiling water. In fact, it not only boils, but also captures the released steam and condenses it in a separate container.
Ion exchange
These filters are made of many boiling stone beads. These beads contain sodium ions. When hard water passes through the filter, it contains magnesium and calcium. Ions in zeolite beads are as good as magnesium and calcium than sodium, so they capture them and release their own sodium.
Reverse osmosis
Reverse osmosis water filtration system usually has more than one filter. In fact, most reverse osmosis systems have three front membrane filters, one semi permeable membrane and one post membrane filter. Depending on the model, some of them also have other filters. The most important filter is semi permeable membrane, also known as reverse osmosis membrane. The filter blocks contaminants based on their size and molecular weight, so only a small number of compounds pass through.
How does the water filter work
Activated carbon
These filters are by adsorption. In this process, gases and liquids are attracted to other liquids or solids. As water passes through the carbon filter, most of the common impurities are attracted to the surface of the carbon sponge, filling the deep ridges on the surface.
Although charcoal filter can remove most pollutants well, one of its disadvantages is that it can not stop scale. Charcoal also won't attract other pollutants, so nitrates, fluoride, sodium and microbes will continue to flow through the water. Another disadvantage is that over time, ridges in the charcoal will become clogged, so the filter will not be able to catch more pollutants. Therefore, you must change the filter regularly.
Distillation
These filters work by boiling water and capturing the resulting steam. When the steam cools, it condenses into water and is collected in a container. The boiling temperature of water is lower than that of most common contaminants, so as the steam rises, they will remain in the original container. Unfortunately, other pollutants actually boil before the water boils, so the condensed steam also carries them into a second container.
Ion exchange
The zeolite beads in the ion exchange filter are filled with sodium ions. As hard water passes through the beads, ions are attracted to the magnesium and calcium components of the water, releasing sodium for exchange. Magnesium and calcium are the main ingredients in scale, so without calcium and magnesium, water will become softer and taste better. However, the released sodium will be present in the water and will become salty. Some people may not like the new taste, while others may not be allowed to drink because of their strict diet.
Reverse osmosis
The filtration system uses at least five filters, sometimes even more. The first filter removes rust, dust, debris and other contaminants that may damage the RO membrane. The second filter is usually a carbon filter, which blocks harmful chemicals such as chlorine, fluoride, etc. The third filter is also a carbon filter, but has a higher density, so it can capture smaller particles, ensuring that the water reaches the membrane almost free of contaminants.
The fourth filter is a reverse membrane, which will block pollutants according to their size, molecular weight and ionic charge. 95
– 99% of the pollutants in the water will be blocked. The fifth filter ensures the removal of bacteria, viruses, residual chlorine and any bad taste or odor. Some models will also be equipped with ultraviolet lamps and special filters to increase the pH of the water.We are
