Using UV Technology to Generate Oxygen Radicals for Paper Mill Systems

摘要

Ultra Violet (UV) light has been used for many years in municipal water systems to disinfect and treat drinking water. UV technology is one way to do an Advanced Oxidative Process (AOP). Advanced oxidation processes, in a broad sense, are a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials in water and waste water by oxidation through reactions with hydroxyl radicals (OH). AOP's generated hydroxyl and oxygen radicals have higher oxidation potential than chlorine and ozone and a faster reaction time for attacking organic contaminants. AOP's are recognized as safe and "green" as they do not have any harmful byproducts. Historic barriers to AOP generation have been complexity and cost. We (Paradigm Chemical) have found a way to use UV technology to generate hydroxyl radicals from ambient air and apply them in paper mill systems to control microorganisms, anaerobes, and positive metal ions like calcium. The system is designed to take a set amount of ambient air, at a set temperature range, and pull it across UV lamps for a set amount of time to convert the maximum amount of oxygen to oxygen radicals. Then, take the gas generated and apply it to a water, or air source to treat and clean. This technology has been proven highly effective against bacteria, anaerobes, algae, viruses & parasites. It has also been shown to remove and prevent scale build up. It can also remove and control H2S and other odors in a system. This technology can be contained in a cabinet that plugs into a standard outlet to produce just over 3 CFM of gas. One unit can treat up to 1MM GPD of water depending on contamination levels and goals.
