People looking to purify their drinking water are constantly on the lookout for new and improved technologies. UV sterilization, ultrafiltration, or reverse osmosis all have benefits that make them worth considering when it comes to residential consumers’ needs – which one should you choose?
Apart from the three water filtration procedures, we also introduce high-tech hydrogel as a highly efficient water purifier technology. Reverse osmosis, ultraviolet, ultrafiltration, and hydrogel are all types of water purification systems.
UV light sanitizer
Water you drink may be contaminated with germs that cause illness. Water treatment methods are available to eliminate microorganisms. UV disinfection is effective in eliminating almost all kinds of bacterial contamination. In our previous blog, we covered the features and functions of UV disinfection in depth: Improving Drinking Water Through Ultraviolet Disinfection
Working principle of ultraviolet sterilization
UV light is similar to natural sunlight. Because UV light falls between visible light and X-rays, it is nameless. UV radiation may harm a microorganism’s cellular activity, preventing it from growing. Water can also be sterilized using UV radiation, as well as waterborne disease-causing germs and viruses.
The LED ultraviolet sterilizer is a safer, more efficient technology than the mercury light. The UV disinfection system comprises of LED light bulbs that generate illumination; incandescent light bulbs are 20% less efficient. There is no mercury in the sterilizer, so you won’t have to worry about dangerous mercury leaks. The Waterdrop RO water filter with UV light is the most advanced water filtration system on the market. This can eliminate most contaminants in drinking water.
Hydrogel Purification
Hydrogel is a relatively new water treatment method. The device creates hydrogen peroxide, which stops bacteria growth and kills them by blocking their metabolism. Gel-polymer hybrid materials have been used recently to create a less expensive and smaller footprint water purification technique.
Hydrogel is a kind of bioadhesive plastic that has excellent photothermal and biocidal resistance. These features might be used as solar evaporators to produce continuous water purification. Under direct sunshine, hydrogel produces water vapor that can be collected in a condenser for drinking water supply.
The hydrogel purification process is non-toxic, environmentally friendly, and does not produce hazardous byproducts. When used as oral tablets, the hydrogel may disinfect over 99.999% of water in 60 minutes or less using no electrical power source.
Hydrogel does not need energy to function, and it generates no hazardous by-products. Furthermore, it is a cost-effective approach with the potential to revolutionize the water purification business in the near future. Hydrogels have advantages as well as disadvantages, such as their speed.
Ultrafiltration
Ultrafiltration is a form of membrane filtration that protects drinking water from germs, viruses, and other pollutants. When the ultrafiltration system is in use, water passes through a 0.01micron membrane. Particles that can’t go through the membrane stay outside of it while fresh water and dissolved minerals flow through.
Similarly, ultrafiltration can remove bacteria and viruses effectively. Furthermore, the system does not need power to operate. Instead, natural pressure is used to filter water. You won’t have to worry about power outages or electricity bills with this zero-power water purification method because it doesn’t require any electricity.
Summarily
UV radiation and ultrafiltration are common water purification methods used in water purifiers. Because advanced water filtering technologies, many water purifiers utilize UV sterilization and ultrafiltration. Although it is a novel technology, hydrogel still needs to be tested and verified before being put into action.
UV sterilizers filter out 99.9% of pollutants, making it somewhat better than ultrafiltration. UV sterilization systems also cost more than ultrafiltration machines. To date, hydrogel’s actual efficiency and price have not been established.
Using a single purification method is not recommended, because each technology has advantages and drawbacks. As a result, it’s preferable to use a multi-step purification technique that includes several filtering methods.
