We all know that the direct drinking fountains on the market can be roughly divided into reverse osmosis drinking fountains and ultrafiltration drinking fountains according to the purification system of the drinking fountains, but many consumers cannot distinguish between the two concepts. In the direct drinking water industry, there are various water treatment technologies, but there are only two best-selling direct drinking water dispensers in the direct drinking water market. What is the difference? Let's follow the editor of Kaiwei direct water dispenser to understand the difference between the two!

1. Mainly from the filtration accuracy of the filter element

As we all know, the best filtration precision on the market is reverse osmosis membrane. Its water-making process is similar to that of ultrafiltration membrane, but its filtration precision is more fine, which can filter 0.0001 mm, plus pre-PP, activated carbon, etc., , No matter the water quality is good or bad, it can achieve the effect of direct drinking, and the water quality of the effluent reaches the standard of pure water, and the ultrafiltration direct drinking water machine mainly uses the ultrafiltration membrane, whose filtration density is not as good as the reverse osmosis membrane of the reverse osmosis direct drinking water machine. It is suitable for areas with better water quality in the south.

2. The ratio of wastewater between the two

It is understood that the wastewater ratio of the reverse osmosis water dispenser currently on the market is 1:3, while the wastewater discharged from the ultrafiltration machine is not much, so many people will also use it for comparison when purchasing a direct water dispenser.

3. The flow rate of the water

The effluent flow of the ultrafiltration direct drinking water machine is larger than that of the reverse osmosis direct drinking water machine, generally 60-80L/H, while the reverse osmosis direct drinking water machine is generally smaller because of its fine filtration precision. If the water supply of the water dispenser is insufficient, a pressure barrel is generally configured.

4. The price of both

Anyone who has been exposed to direct drinking fountains knows that because the reverse osmosis filter element has a high cost and complicated structure, the price of reverse osmosis drinking fountains is generally higher than that of ultrafiltration drinking fountains.

According to the difference between the above reverse osmosis water dispenser and ultrafiltration water dispenser, the difference between the two is not very big, but if consumers want better filtering effect, the editor suggests that they can choose reverse osmosis water dispenser. It is recognized that the water purification effect is remarkable.
