Abstract

Direct electrical energization methods for removal of persistent substances ITom water are under investigation in the framework oftheytriD-project. The emphasis of the first stage of the project is the energy efficiency. A comparison is made between a batch reactor with a thin layer of water and an aerosol reactor. The method of energization is mainly the application of fast pulses. In case of the batch reactor it is compared with DC. The ozon concentration is determined as an indicator for the efficiency of the chemical reactions, the yieldis 4 g/kWh for the DC batch reactor, 50 g/kWh for the pulsed batch reactor and up to 200 g/kWh for the aerosol reactor. For initial testing phenol degradation is determined. 50% of the initial 0.1 mM is reached in 8 minutes in the pulsed batch reactor. The phenol removal yield is several grams per kWh up to now. Matlab simulations show that the surface-volume ratio is an important parameter for the speed of phenol degradation. This conclusion is also obtained from the experiments.
