  • Prediction of advanced oxidation performance in UV/H2O2 reactor systems with LP-UV lamps

    Advanced oxidation processes, like UV/H2O2 oxidation, are important barriers against organic micro pollutants in drinking water treatment. In order to guarantee safe drinking water, it is important to be able to predict the reactors' performance to adjust the operating conditions to the actual influent water characteristics (like UV transmission) and lamp performance. Therefore, a design tool was ...

  • A Comparison Of Microbial Repair Mechanisms With Low Pressure And Medium Pressure UV Lamps

    Introduction It is well-known that bacteria and other microorganisms are capable of repairing their DNA following damage by ultraviolet (UV) radiation. Known as ‘reactivation’, it is a natural defense mechanism that has evolved over millions of years. Some microorganisms need visible light in order to repair their DNA (known as ‘photoreactivation’), while others can repair their DNA without light ...
