In modern office and home environments, the filtration system of Desktop Water Dispenser has become the focus of people's attention. Whether it can effectively purify water is crucial to protecting the health of users.
Generally speaking, a high-quality desktop water dispenser filtration system uses a combination of multiple filtration technologies. Common ones include activated carbon filtration, ultrafiltration membrane filtration, and reverse osmosis membrane filtration. Activated carbon filtration can effectively remove odor, residual chlorine, and some organic pollutants in water. For example, in urban tap water, there is often a certain amount of chlorine left. Activated carbon can adsorb chlorine molecules through its porous structure, which significantly improves the taste of water and removes the pungent chlorine smell. At the same time, it can also adsorb some possible pesticide residues, volatile organic compounds, etc., and reduce the content of harmful substances in water.
Ultrafiltration membrane filtration performs well in removing macromolecular substances. Its pore size is generally between 0.01-0.1 microns, which can intercept bacteria, colloids, macromolecular organic matter, etc. in water. For some water sources that may contain microbial contamination, ultrafiltration membranes can act as a good barrier to prevent bacteria from entering the human body and ensure the microbial safety of drinking water. In some areas with poor water quality, ultrafiltration membrane filtration can significantly improve the clarity of water quality and make the water look purer.
Reverse osmosis membrane filtration is a more sophisticated filtration technology. Its pore size is extremely small, and it can remove tiny pollutants such as soluble salts and heavy metal ions in water. Taking heavy metals such as lead and cadmium commonly found in water as an example, reverse osmosis membranes can effectively intercept them to prevent these harmful substances from accumulating in the human body and causing damage to the kidneys, nervous system, etc. For people who have extremely high requirements for water quality, such as infants, the elderly or people with specific diseases, desktop water dispensers equipped with reverse osmosis membrane filtration can provide drinking water that is closer to the standard of pure water.
However, for the filtration system to continue to work effectively, regular replacement of the filter element is the key. As the use time increases, the filter element will gradually become saturated and the filtration effect will decrease. For example, activated carbon filters will lose their activity due to the adsorption of too many pollutants, and ultrafiltration membranes and reverse osmosis membranes will also reduce filtration efficiency due to clogging. It is generally recommended to replace the filter element in a timely manner according to the time interval specified by the manufacturer or based on water quality monitoring to ensure that the filtration system is always in good working condition.
