Introduction to the characteristics and application scope of ultrapure water system

The characteristics and application scope of ultrapure water system introduce the characteristics of ultrapure water system:

  1. High-purity performance and stable water quality;
  2. Low operating cost, simple operation and convenient maintenance;
  3. Continuous operation and regeneration, 24 hours uninterrupted water supply;
  4. No wastewater treatment problems, no need for medicine regeneration and no medicine storage problems;

Water production characteristics of ultrapure water system:

Produced water quality> 16MΩ-cm Recovery rate: 90%-95%

Water inlet requirements of ultrapure water system:

TEA (including CO2) <25mg/L as CaCO3 PH 5-9
Hardness <1mg/L as CaCO3 Silicon <1mg/L
TOC <0.5mg/L Residual chlorine <0.05mg/L

Application range of ultrapure water system:

Circumstances that require high-purity water, such as biochemical products in the pharmaceutical industry, life sciences, chips, semiconductors, and imaging control processes in the electronics industry.
The EDI system was used in pure water systems as early as the 1990s, but due to the high initial price and immature technology, it could not completely replace the traditional ion exchange system. In recent years, the company has cooperated with well-known foreign companies and has been committed to the research of the application technology of the product in practice. At present, the application technology of the EDI system is quite mature. At the same time, the price is greatly reduced due to the increase in output. In addition, Because the system has the advantages of high purity, stable water quality, small footprint, no need for drug regeneration, no waste water discharge, simple operation, and convenient management, it is an inevitable trend for the development of water treatment to replace the traditional ion exchange system with the EDI system.
