Abstract

Previous research showed that surface water in the Netherlands may contain significant concentrations of organic micropollutants like pharmaceuticals. A model has been developed which can predict the conversion of a broad range of organic micropollutants in a UV/H2O2 process with low pressure UV lamps. This model also was applied to optimize UV reactors, which were tested at three Dutch locations, including two drinking water companies. It was observed that the model predictions were very accurate, that very high conversion could be obtained, and that the optimized UV reactors resulted in a 30-40% reduced energy demand of the process. Furthermore it was shown that the effect of pretreatment of the water, reducing the DOC content and increasing UV-T values, can improve reactor performance by 30-70%.
