Description

Technical Field

[0001] This utility model relates to the field of pure water machine technology, specifically a TOC removal device for pure water machines. Background Technology

[0002] A laboratory ultrapure water system is a water purification device for laboratories. It is a water treatment device that removes all solid impurities, salt ions, bacteria, viruses, etc. from water through methods such as filtration, reverse osmosis, electrodialysis, ion exchange, and ultraviolet sterilization. TOC refers to the total organic carbon in water, usually expressed in milligrams per liter (mg / L) or micrograms per liter (μg / L). The TOC content in water is a key indicator affecting water quality.

[0003] In existing technologies, when purifying water using a water purifier, ultraviolet light is usually used to irradiate the water to remove total organic carbon (TOC). Ultraviolet lamps can use photo-oxidation of organic compounds to reduce the total organic carbon concentration in ultrapure water. However, the existing TOC removal devices are relatively cumbersome to install and remove when using ultraviolet lamps, and subsequent maintenance is also inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a TOC removal device for a pure water machine to solve the problems mentioned in the background art.
