Why should purified water equipment desalinate pretreated water?

With the development of technology, the requirements for purified water in various industries are also gradually increasing
.

From the previous distillation process to the application of the reverse osmosis desalination process, the purified water production industry is also developing rapidly
.

Let's talk about why purified water equipment desalinates pretreated water
.

The main reason for desalination of pretreated water is that the water quality is different due to different environmental factors such as geology and climate in different places, and the actual situation such as demand, discharge and site for purified water in various industries also vary.
Therefore, it is necessary to design a special reverse osmosis desalination process according to different water quality
.

Figure 1 Jingderui purified water equipment must first analyze the local water quality data in detail, which is a necessary step to determine the design of reverse osmosis pretreatment
.

Secondly, the change trend analysis is carried out according to the characteristics of the local water source, which is an important basis for the rational design of the water treatment system
.

Carefully confirm and analyze the specific indicators of purified aquatic water quality, so as to design the components of the reverse osmosis desalination system and the selection of membrane elements according to the indicators
.

It should be noted that sometimes the water that has been desalinated by reverse osmosis RO cannot be directly used in the production process, and EDI electrodeionization depth desalination is required before it can be put into use
