Difference 1: Purification effect
The core filtration membrane of ultrafiltration machine is ultrafiltration membrane, also called UF membrane. The nameplate of the product will say "UF", and the filtration accuracy is 0.0 1 micron, which can effectively remove impurities, rust and residual chlorine. Tap water, but can't filter out viruses, heavy metals, etc. Because the virus in urban tap water is disinfected by residual chlorine, heavy metals cannot exceed the standard. In addition to the water crisis, ultrafiltration machine is relatively safe to be used in urban tap water.
The core filtration membrane of reverse osmosis machine is reverse osmosis membrane, also called RO membrane. The product nameplate will say "RO", and the filtration accuracy is 0.000 1 micron. Only water molecules can pass through the RO membrane and stay in the body for direct drinking. Bacteria, viruses and heavy metals can't pass through RO membrane to become sewage, which ensures the safety and reliability of water quality. Whether there is a water crisis or not, the water quality passing through the reverse osmosis machine is very safe.
Difference 2: electricity consumption
Ultrafiltration machine can work normally without electricity, as long as the water pressure reaches 0.06Pa and the minimum water pressure of urban tap water is 0.3Pa, so it can work without electricity as long as it is connected to tap water.
Reverse osmosis machine needs electricity to ensure normal operation. The pore size of RO membrane is only 0.000 1 micron, and the tap water pressure cannot let water molecules pass through, so it needs a booster pump to work normally. The booster pump consumes electricity only when the water purifier works, and the power is relatively low, so it doesn't use much electricity.
Difference 3: Wastewater situation
Ultrafiltration machine does not produce wastewater in purification work, which is relatively water-saving.
The reverse osmosis machine will produce wastewater in the purification process, and the proportion of wastewater produced by different technical levels is different. Generally, there is more than 1: 2, that is, purifying 1L water will produce 2L wastewater.
Angel was selected as the brand of water purifier, and Angel Company was founded in 1987. 1988 developed the first water purifier; The first drinking machine was developed in 1993. Angel has been deeply involved in the field of water purification for 33 years, participated in the formulation of 14 national and industrial standards, and has 768 patents. He knows more about the water quality in China and develops water purification products that are more suitable for families in China. The appearance of long-acting reverse osmosis membrane has broken the monopoly of foreign reverse osmosis membrane technology. Products sell well in 65 countries, such as the United States and Japan, and have won the choice of 200 million people around the world.
