The differences between ultra-pure water equipment and pure water equipment

In simple terms, ultra-pure water equipment and pure water equipment are devices used to make ultra-pure water and pure water respectively. The differences between ultra-pure water equipment and pure water equipment are mainly reflected in three aspects: produced water quality, treatment process and application industry.

1. Produced water quality

Under normal circumstances, the electrical conductivity is used to measure pure water, and the electrical resistivity is used to measure the quality of ultra-pure water. Generally, the electrical conductivity of 1-10μs/cm is pure water, and the resistivity of 1-18 MΩ·cm is ultra-pure water. This is the difference in the quality of produced water.

2. Processing technology

Pure water equipment for making pure water generally uses the ion exchange process (relatively primitive), and modern practices mostly use reverse osmosis devices as the main preparation process. In some industries, a secondary reverse osmosis process is also used. According to the difference of raw water, there are not exactly the same pretreatment processes at the front end of reverse osmosis.

The ultra-pure water equipment for making ultra-pure water will have a mixed bed on the basis of the reverse osmosis device, and the mixed bed is also a type of ion exchange process. However, most modern practices will use EDI devices as the main preparation process of ultra-pure water. According to the difference of water requirements, the back-end treatment process is not exactly the same.

3. Application industry:

Pure water equipment is mostly used in industries where the water requirement is not too high, such as surface treatment, fine washing chemicals, primary cleaning of plastics and hardware parts; The ultra-pure water equipment is mostly used in industries with particularly high water requirements, such as the cleaning of flexible circuit boards, the cleaning of mobile phone glass cover plates, the manufacturing of camera modules, display modules, semiconductors and so on.

In general, the concept of pure water and ultra-pure water is more diluted in practical applications, and we are more targeted to give reliable solutions according to the raw water situation and high water requirements.
