Difference 1: purification effect
Ultra-filtration machine for the core of the ultra-filtration membrane, also known as the UF membrane, in the product nameplate will be written "UF", the filtration accuracy of 0.01 microns, can effectively remove impurities in the tap water, rust, residual chlorine, etc., and can not filter out the tap water! It can effectively remove impurities, rust, residual chlorine, etc. in tap water, but cannot filter out viruses and heavy metals in tap water. As the virus in city tap water is eliminated by residual chlorine, heavy metals cannot exceed the standard. In addition to the water crisis, ultrafiltration machine for urban tap water is relatively safe.
Reverse osmosis machine for the core of the filtration membrane for reverse osmosis membrane, also known as RO membrane, in the product nameplate will be written on the "RO", filtration accuracy of 0.0001 microns, only water molecules can be passed through the RO membrane and retained for direct drinking, bacteria, viruses, heavy metals can not be passed through the RO membrane, become sewage discharge, to ensure the safety and reliability of water, regardless of the occurrence of a water crisis. Ensure that the water quality is safe and reliable, whether or not a water crisis, the water quality through the reverse osmosis machine is very safe.
Difference two: electricity
Ultra-filter does not need electricity to work normally, as long as the water pressure reaches 0.06Pa, ultra-filter can work normally, the minimum requirement of the city tap water pressure of 0.3Pa, so the ultra-filter as long as connected to the tap water can work, without electricity.
Reverse osmosis machine needs to be energized to ensure normal operation, RO membrane pore size of only 0.0001 microns, tap water pressure can not let the water molecules through the need for a booster pump in order to work properly, the booster pump will only consume electricity when the water purifier work, the power is relatively low, spend not much electricity.
Difference three: waste water
Ultra-filtration machine in the purification work does not produce waste water, relative savings in water.
Reverse osmosis machine in the purification work will produce wastewater, different levels of technology, produce wastewater ratio is different, generally 1:2 more, that is, purify 1L of water, will produce 2L of wastewater.
Water purifier brand on the choice of Angel, Angel company was founded in 1987. 1988 developed the first water purifier; 1993 developed the first water dispenser. Angel ploughing the field of water purification for 33 years, participated in the development of 14 national and industry standards, with 768 patents, more understanding of China's water quality, research and development of water purification products more suitable for Chinese families, long-lasting reverse osmosis membrane was introduced, is to break the monopoly of foreign reverse osmosis membrane technology. Products sold in the United States, Japan and other 65 countries, won the global 200 million people choose.
