Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and in particular relates to a purification device for secondary utilization of concentrated water. Background Art

[0002] In the cosmetics production process, ultrapure water is generally required. Ultrapure water refers to water with a conductivity of 0.1μS / cm 2 This water is composed of almost no impurities except water molecules, so it is very suitable for the production of cosmetics. The raw material for the production of ultrapure water is generally tap water. First, the tap water is treated by two pre-filters to obtain a conductivity of 10μS / cm 2 The following source water, then the source water is introduced into the pure water EDI equipment and processed to a conductivity of 0.1μS / cm 2 About 1 / 2 cup of ultrapure water will do.

[0003] However, the above ultrapure water preparation process has some defects. For example, the conductivity of tap water fluctuates greatly (minimum 100 μS / cm 2 Around, up to 500μS / cm 2 About), and for the normal operation of the pure water EDI equipment, the filtering standard of the two pre-filtering devices is often the tap water with the highest conductivity. This results in a lower proportion of pure water and a higher proportion of concentrated water in the composition of the source water treated by the two pre-filtering devices. According to this proportion, after being treated by the two pre-filtering devices and the pure water EDI equipment, 10 tons of tap water can only produce about 1 ton of ultrapure water, and the entire purification process still has about 9 tons of concentrated water surplus. The extraction efficiency of ultrapure water is low, and the utilization rate of the water resources used is not high. Utility Model Content
