The filtration system of Freestanding Water Dispenser is a key part to ensure the quality and taste of drinking water. According to different filtration technologies and designs, filtration systems can be divided into many types.
1. Activated carbon filtration:
Activated carbon filtration is one of the most common filtration technologies. It absorbs organic matter, chlorine, odor and color in water through porous activated carbon particles.
Activated carbon filtration system can effectively remove odor and impurities in water and improve the taste of water.
2. Ultrafiltration (UF) system:
The ultrafiltration system uses ultrafiltration membranes with extremely small pore sizes, which can intercept suspended matter, bacteria, viruses, macromolecular organic matter, etc. in water.
The ultrafiltration membrane allows water molecules and dissolved solids (such as minerals) to pass through, while removing microorganisms and particulate matter in the water, providing relatively pure drinking water.
3. Reverse osmosis (RO) system:
The reverse osmosis system is one of the most advanced water treatment technologies. It uses semi-permeable membranes to remove dissolved solids, bacteria, viruses, organic matter and heavy metals in water.
RO membrane can intercept most impurities, so that the effluent water reaches the standard of pure water, which is suitable for users with high requirements for water quality.
Reference article 4 mentioned that some Freestanding Water Dispensers use a 5-stage reverse osmosis system, which combines multiple filtration technologies to provide more comprehensive water purification.
4. Ultraviolet disinfection:
The ultraviolet disinfection system uses ultraviolet light to destroy the cell structure of microorganisms in the water to achieve the purpose of sterilization and disinfection.
This system is usually used in combination with other filtration technologies as the last line of defense to ensure the microbial safety of water quality.
5. Composite filtration system:
The composite filtration system combines multiple filtration technologies such as activated carbon, ultrafiltration, reverse osmosis and ultraviolet disinfection to provide more comprehensive and efficient water purification.
This system can be customized according to the specific needs of the user and the water quality conditions to achieve the best filtration effect.
