With the improvement of people's living standards and physical and mental health concepts, more and more customers are considering purchasing water purifiers and improving their home tap water standards. Their main concern is direct drinking from terminal equipment, with ultrafiltration equipment and RO reverse osmosis machines being more common. However, there are a wide range of well-known brands in the sales market, with prices ranging from hundreds to tens of thousands of yuan. How should customers choose?

First, briefly introduce the definitions of ultrafiltration equipment and RO reverse osmosis machine:

1. The key selection of ultrafiltration equipment is the treatment equipment using ultrafiltration membrane processing technology. Most of the sales in the market are two-stage filter cartridges, primary PPF (PPcotton), and two-stage double-layer composite filter cartridges (Dow reverse osmosis membrane, activated carbon, folding membrane, etc.).

RO reverse osmosis machines (commonly referred to as water purifiers) use RO reverse osmosis membrane separation technology as the key treatment equipment. At present, most of the sales on the market are five stage filter elements, PPF activated carbon PPF (activated carbon) RO film. Rear camera carbon.

But it's a key difference. What customers know is that they don't plug in or discharge sewage, and they can't remove scale. Ultrafiltration equipment also has dual layers, RO reverse osmosis machines, bottom pressure membranes, and RO reverse osmosis machines!

Therefore, customers also cannot find the direction and are unsure how to choose!

1、 The condition of initial water resources.

For example, for municipal engineering drinking water, the water collection points are generally large rivers, water conservancy hubs, lakes, etc. Different regions, rural areas, and big cities have different process treatments, and some regions also use surface water (river water). The raw water quality in the vast majority of southern regions is good, with less water pollution and lower intensity in the upstream and downstream of rivers. The ultrafiltration function meets the requirements, while the raw water quality in southern regions is weak, the process treatment is outdated, and environmental pollution is relatively serious. Therefore, it is better to use RO reverse osmosis machines.

2、 Installation standards.

For example, in terms of space size, most ultrafiltration equipment has a smaller volume than RO reverse osmosis machines, and the space requirements are not high. The common secondary ultrafiltration machines have two types: RO reverse osmosis machines with and without buckets, which take up a certain amount of space and have relatively small relativity without buckets. Therefore, if the raw water is very good, the restaurant kitchen does not have a power switch, and the space is not large, then choose an ultrafiltration machine. If the raw water is not very good, the space and power switch are insufficient, then choose RO reverse osmosis. In addition, if there is a pipeline machine, it is better to choose RO reverse osmosis.

3、 I like it.

Taste buds are loved by some people on both the UF and RO reverse osmosis platforms. The taste buds of the effluent from ultrafiltration equipment and RO reverse osmosis machines are different and subjective. In theory, ultrafiltration machines are close to UF, while RO reverse osmosis machines are close to the platform. In terms of dirt problems, the vast majority of ultrafiltration machines cannot remove scale or have a short service life. If you care about dirt, you don't need to choose ultrafiltration machines. Reverse osmosis machines have a very high sludge load on dirt, usually reaching 92% -98%.

4、 Brief description.

How to choose a suitable direct water dispenser ultrafiltration equipment for oneself should be based on local raw water quality, installation space standards, personal interests, and cost budget, and comprehensively considered.
