Short-wave UV/UVC germicidal lamp with 253.7 nm for prolonged and effective disinfection Suitable for areas up to 400 sq ft. like living rooms, bedrooms, kitchens, bathrooms and more. Safe to use: A sign on the bulb indicates that the bulb produces UVC wavelengths.

L ightSources & LightTech’s low-pressure, mercury-arc germicidal 254 nm UV lamps are specially designed to produce the highest amounts of UV radiation – where 90% of the energy is typically generated at 254nm. This radiation is very close to the peak of the germicidal UV254nm transmissivity measurement is used to control UV disinfection processes to account for absorbance by dissolved organics and suspended solids. To ensure efficient sterilisation, the treatment process lamp intensity may be regulated by a control instrument measuring UVT. Although > 90 % of the influent BOD5 could be removed in an activated sludge process, the effluent still contained high amounts of resistant substances. The maximum COD removal was about 50 %; the removal rates achieved in the parameters TOC, DOC, AOX, SAK (254 nm) were even lower. The biological treatment led to an increase in… Expand Keep in mind that methylene chloride absorbs light with wavelengths below 254 nm.

Bei der Bestimmung des Spektralen Absorptionskoeffizienten bei 254 nm (SAK 254) handelt es sich um eine Charakterisierungsmethode für gelöste organische Wasserinhaltsstoffe. Es werden zwar nicht alle gelösten organischen Stoffe erfasst (→ DOC), aber es ergibt sich ein gutes Maß für die Belastung eines Wassers mit organischen Stoffen.

UV-Absorption (SAK 254 nm) Viele gelöste organische Verbindungen absorbieren ultraviolettes Licht (UV-Licht, z.B. Verbindungen mit C=C oder C=O Doppelbindungen wie Aromaten). Die Messung der UV-Absorption stellt einen eigenständigen, geeigneten Summenparameter für die Wasserbelastung durch gelöste organische Substanzen dar. UV Lamp 254nm/365nm 4W Portable UVA/UVC Shortwave Longwave Lab Blacklight Batteries Included AAdvance Instruments AI-0UV19 254) is commonly used to characterize the organic constituents in a water sample. Research has shown that organic compounds absorbing at 254 nm have a greater tendency to form chlorinated disinfection by‐products (DBPs) when contacted with chlorine in the disinfection of drinking water. A 185 nm lamp is also referred to as an Ozone lamp. This lamp produces 185 nm in addition to the 254 nm.
