{"product_id":"9781843399193","title":"Innovative Uv Technologies To Oxidize Organic And Organoleptic Chemicals","description":"Recent regulations are now requiring lower chlorinated disinfection by-products (DBPs) and inactivation of chlorine resistant pathogens such as Cryptosporidium parvum. Ultraviolet light is now considered a compliance technology for primary disinfection of surface waters in the Stage 2 Rules. The objectives to this project were to: evaluate the efficacy of three different UV technologies for treatment of organic contaminants in waters of varying quality; evaluate the UV technologies with additions of hydrogen peroxide (H2O2) to promote advanced oxidation (AOP) for treatment of the contaminants; determine the extent of disinfection by-product (DBP) formation including aldehydes, carboxylic acids, and post-chlorination DBPs, following UV treatment; pilot test two UV technologies alone and under AOP conditions at two utility field sites for contaminant treatment to develop operational experience and preliminary cost and design data.","brand":"IWA Publishing","offers":[{"title":"Default Title","offer_id":47032526504176,"sku":"9781843399193","price":226.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781843399193_p0.jpg?v=1763741541","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781843399193","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
