Presentation on IUVA World Congress Spotlights Water Disinfection Technologies 2017, Dubrovnik, Croatia<\/a><\/strong><\/p>\nAbstract <\/em>
\nIn UV water purification applications UV sensors are monitoring the dosage of UV irradiation as according to O\u0308NORM and DVGW standards. sglux GmbH is manufacturing such sensors employing opaque synthetic quartz-glass diffusers as entrance windows. This paper investigates the influence of high-intensity UV irradiation on the transmission behavior of these diffusers. Quartz-glass and micro-porous quartz-glass were investigated. The sensors were continuously monitored while irradiated by a 1kW medium pressure Hg lamp with a total UV irradiance of 1000mW\/cm\u00b2 for 800 hours. Before and after the aging period the total transmissions of the diffusers were measured.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"","footnotes":""},"categories":[308,51],"tags":[393,480,488,489,491],"class_list":{"0":"post-10313","1":"post","2":"type-post","3":"status-publish","4":"format-standard","6":"category-publications-and-reports","7":"category-research","8":"tag-diffuser-en","9":"tag-irradiance_hi-en","10":"tag-science-en","11":"tag-sensors-en","12":"tag-stability-en","13":"entry"},"acf":[],"yoast_head":"\n2017 - Degradation of opaque quartz-glass diffusers under high intensity UV irradiation | sglux<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/sglux.de\/en\/2017-degradation-of-opaque-quartz-glass-diffusers-under-high-intensity-uv-irradiation\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"2017 - Degradation of opaque quartz-glass diffusers under high intensity UV irradiation | sglux\" \/>\n<meta property=\"og:description\" content=\"N.
