Oxidative Treatment of Raw Water with High DOM-Loading -Partial Project in Core Project C in the Main Project: Export Oriented Research and Development on the Field of Water Supply and Water Disposal
(Export)

The aim of the project is the application oriented examination and the optimization of oxidation processes for the treatment of high NOM and algae loaded raw water with simultaneous presence of interfering substances like ammonium, iron and manganese. The investigated oxidation processes are based on the AOP-technology (Advanced Oxidation Processes). For an optimal removal of the loading the oxidation processes were combined with a previous flocculation and a subsequent biological degradation.

The examinations focus on the reaction conversion, the effect of interfering substances at the different stages in the treatment, and on the comparability of the different oxidation processes. The results will be compared with those of a classic ozonization. Furthermore the biological treatment and the formation of degradation products which are relevant to the drinking water are examined. The objective of the project is the evaluation of combined oxidation processes with respect to their efficiency, feasibility, profitability, and marketing chances. The final objective of the project is the compilation of a technical guide for the treatment of different raw waters with high DOM-loading by oxidation and biological treatment for the international market.
