To extend the effective life of the filter, the most fundamental way is to stand in the pre-filter dust. Replace the pre-filter is generally no need to stop production ICU purification, no debugging, so owners will have experienced the attention and money spent on the pre-filter and protect middle-class filter. For the 10K and 100K clean room grade, pre-filter selection G4, intermediate choice F8 filter (assay 95%), so that the end of the effective life of the filter is generally up to 5 years. Foreign and domestic projects in the new project, F8 filter non-uniform flow clean room the most common pre-filter. Primary filter typically replaced every 2-3 months, once every six months to replace, so efficient filter life generally in more than 2 years. UV mainly by microorganisms (bacteria, viruses, spores and other pathogens) radiation damage and destruction of the nucleic acid function lethal microorganisms ICU purification price, so as to achieve the purpose of disinfection. Ultraviolet light can result in bond of nucleic acids and strand breaks, interstrand crosslinking and the formation of photochemical products, etc., thereby changing the biological activity of DNA ICU decontamination experts, so the microorganism itself can not be copied, this UV-induced damage is lethal damage . UV disinfection is a physical method, which does not add any substance to the water, no side effects, this is it better than chlorination place, it is usually used in combination with other substances, a common joint process are UV + H2O2, UV + H2O2 + O3, UV + TiO2, so that disinfection would be better.
