重庆官方网站（RO）净水器和重庆超滤（UF）净水器是重庆净水市场主流的两种净水产品，它们的净水效率要远超过净水壶或龙头式的粗滤净水产品，更加符合人们对于净水效果的期望，关于两大阵营净水器的选购也是众说纷纭。重庆特丽洁健康家整理了两类净水产品的最主要差异，希望可以帮您选到更合适自己的净水器。
Chongqing reverse osmosis (RO) water purifier and Chongqing ultrafiltration (UF) water purifier are two main water purification products in Chongqing water purification market. Their water purification efficiency is much higher than that of crude filter water purifier of water purifier pot or tap type, which is more in line with people's expectation of water purification effect. There are also divergent opinions on the selection and purchase of water purifiers of the two camps. Chongqing Trijie Healthy Home has sorted out the main differences between the two types of water purification products, hoping to help you choose a more suitable water purifier.
超滤与官方网站净水器差异一：净水效果
Difference between Ultrafiltration and Reverse Osmosis Water Purifier I: Water Purification Effect
事实上超滤与官方网站净水器的结构大致相似，他们在超滤膜、官方网站膜前一半都设有PP棉、活性炭等粗滤滤芯，而比较终的差距就在超滤膜、官方网站膜的过滤表现了。一般而言，超滤式净水器的精度大致在0.01-0.1微米，而官方网站膜的过滤精度可以达到0.0001微米，这就好比孔径大小的筛子做对比，明显孔距更小的筛子过滤精度更高。
In fact, the structure of ultrafiltration and reverse osmosis water purifier is similar, they have PP cotton, activated carbon and other coarse filter elements in the first half of the ultrafiltration and reverse osmosis membranes, and the final difference is in the performance of ultrafiltration and reverse osmosis membranes. Generally speaking, the precision of ultrafiltration water purifier is about 0.01-0.1 micron, while the filtration precision of reverse osmosis membrane can reach 0.0001 micron, which is similar to the sieve of pore size. The sieve with smaller pore spacing has higher filtration precision.

就过滤效果而言，超滤净水器可以为你去除水中的铁锈、泥沙、细菌、病毒、余氯、异色异味以及重金属物质等，而官方网站净水器则能进一步过滤掉水中有益以及有害的金属离子，但人体所需的钙镁离子也会随着废水被排出。官方网站净水器的产出物近乎纯水。
As far as filtration effect is concerned, ultrafiltration water purifier can remove rust, sediment, bacteria, viruses, residual chlorine, peculiar smell and heavy metal substances in water for you, while reverse osmosis water purifier can further filter out beneficial and harmful metal ions in water, but the calcium and magnesium ions needed by human body will also be discharged with wastewater. The product of reverse osmosis water purifier is almost pure water.
这两类净水器都是优劣参半，如果生活地区化工不发达，重金属排放正常的话直接选择超滤就好，它会保留钙镁离子；如果生活地区化工用水排放超标，妥妥的使用超滤机芯，别让那些危害健康的重金属离子一并被人体吸收。
These two types of water purifiers have mixed advantages and disadvantages. If the chemical industry in the living area is underdeveloped and heavy metals are discharged normally, it is better to choose ultrafiltration directly, which will retain calcium and magnesium ions. If the chemical water discharged in the living area exceeds the standard, proper use of ultrafiltration machine core should not allow those heavy metal ions harmful to health to be absorbed by the human body.
超滤与官方网站净水器差异二：出水流量
Difference between Ultrafiltration and Reverse Osmosis Water Purifier II: Outflow Flow
如果没有加压，官方网站净水器甚至不会为你生产纯水，它细密的过滤结构会大幅降低出水流速。一般而言官方网站净水器的纯水流量大致为0.1L每分钟左右，也就是说大致要3分钟才能流出一听可乐的纯净水源，因为这种龟速设定官方网站纯水机大多会安装可预先储存数升纯水的储水桶，也会预留一路粗虑的大流量出水龙头。
If there is no pressure, reverse osmosis water purifier will not even produce pure water for you, its fine filtration structure will greatly reduce the flow rate. Generally speaking, the pure water flow of reverse osmosis water purifier is about 0.1L per minute, that is to say, it takes about 3 minutes to flow out the pure water source of a can of cola, because most of the reverse osmosis water purifiers with speed setting will install storage buckets that can store several litres of pure water in advance, and will also reserve a careless large flow tap.
超滤纯水机则无需担心流量的问题，他们每分钟出水大致1.5L，另外市面上有一些400GPD以上的大流量官方网站净水器，流量大致是1.2L每分钟，如果用水量大可要看好出水流量这个关键数值。
Ultrafiltration water purifiers need not worry about the flow rate. They produce about 1.5L of water per minute. In addition, there are some large flow reverse osmosis water purifiers with a flow rate of more than 400 GPD on the market. The flow rate is about 1.2L per minute. If the water consumption is large, we should look at the key value of the flow rate.
超滤与官方网站净水器差异三：废水率
Difference between Ultrafiltration and Reverse Osmosis Water Purifier III: Wastewater Rate
如果进入的原水量与产出净水量相同，说他们能净水估计谁都不相信吧？因此想要得到纯净的健康用水就要牺牲掉一定比例的废水。一般而言超滤净水器的废水很少，但是注意定期打开冲洗口清洗滤芯。与之相比官方网站的净水器就比较浪费了，为了保证官方网站膜的长寿，增大废水比率可以防止官方网站膜结垢损坏。
If the amount of raw water entering is the same as the amount of net water produced, no one will believe that they can purify water. Therefore, a certain proportion of wastewater must be sacrificed in order to obtain pure and healthy water. Ultrafiltration water purifier generally has very little wastewater, but pay attention to regularly open the flushing port to clean the filter element. In contrast, the reverse osmosis water purifier is wasteful. In order to ensure the longevity of the reverse osmosis membrane, increasing the wastewater ratio can prevent the fouling damage of the reverse osmosis membrane.
一般而言，官方网站净水器的废水率在从比较早的5:1发展至已达到3:1甚至是2:1，也就是所产生一杯纯净水让浪费掉相同容积的两杯水。当然，即便是叫“废水”这些水也是很洁净的，他们纯净度高于原水但低于纯水，但盐度较高，用来洗衣服、拖地或是冲马桶便不会白白浪费。
Generally speaking, the wastewater rate of reverse osmosis water purifier has developed from the earliest 5:1 to 3:1 or even 2:1, that is to say, it produces a cup of pure water and wastes two cups of water of the same volume. Of course, even the water called "wastewater" is very clean. Its purity is higher than that of raw water but lower than that of pure water, but its salinity is higher. It is not wasted to wash clothes, mop the floor or flush the toilet.
