On the choice of filter, Especially in some areas of high standards of water use, Choose the ultrafiltration water purifier or RO Reverse osmosis water purification has always been controversial, Today, let's talk about the difference between the two devices, How should we choose according to the actual situation.
First of all, take VLLRO Ultrafiltration water purifier and VLLRORO Reverse osmosis water purifier for comparison, We will find that both units are equipped with pre-sand and carbon processing equipment and precision filters, So in the pretreatment of water quality, They are exactly the same. And then you get to the core of both devices, On the filter membrane, That is to say, the difference between the two devices is mainly the difference between the two filter membranes.
Let's start with ultrafiltration membranes, The filtration accuracy of ultrafiltration membrane is 0. 01 micron, Can remove microorganisms, colloid, Diatoms and other substances that cause turbidity. Good hydrophilicity, Long life, Strong anti-fouling ability, Beneficial minerals can be retained, Larger water yield. And the ultrafiltration membrane has the characteristics of zero waste water, Low cost of use, More suitable for more complex use environment.
review RO Reverse osmosis membrane, ro The filtration accuracy of reverse osmosis membrane is 0. 0001 micron (Millionth of a micron) , It is the filter element with the highest filtration accuracy currently available, Able to filter bacteria, Heavy metal, Organic matter, Residual chlorine, The role of colloids and other harmful substances in water. And through RO The water quality after membrane filtration is the only filtration material recognized by the state that can meet the standard of direct drinking.
As can be seen from the comparison above, with RO Reverse osmosis membrane compared, Ultrafiltration membranes are far less accurate, So the quality of the water is not as good RO Reverse osmosis membrane high, However, this does not mean that the filtration accuracy of ultrafiltration membrane is not good, In fact, except RO Beyond reverse osmosis, Ultrafiltration membrane is still the most accurate filtration membrane on the market, The filtered water quality far exceeds the standard of municipal tap water. It also has zero waste water, Long service life, Low use cost advantage.
So if our water use scenario is not direct drinking water, Then choose ultrafiltration membrane filtration, Regardless of the cost of use, Or maintenance, Ultrafiltration water purifiers are a more cost-effective option.
Of course, If our use case standards are high, The water quality must meet the standards for direct drinking water prescribed by the State, You still have to choose VLLRO RO Reverse osmosis water purifier, It can fully meet our water needs, Traffic customization is also supported, Free scheme design, The full range of your water needs.
