Overall Findings of the Project NADINE (2010 – 2013)

The project NADINE aimed at developing particularly efficient nano-modified diamond electrodes for use in different applications under realistic conditions. These methods should improve sustainably the conditions of human health and environment and increase considerably the reuse of water resources.

NADINE Pilot Applications

 

All pilot lines applications clearly demonstrated an efficient disinfecting effect. With the usage of nano-modified diamond electrodes, the efficiency could be increased significantly. However, for continuous operation an integrated descaling process is required.

Overview Table on NADINE Pilot Line Applications

 

Achieved project results:

  • Nano-modified diamond electrodes with specific electrochemical behaviour were developed
  • Nano-modified diamond electrodes form negligible amounts of organic electrolysis by-products such as trihalomethanes (THMs)
  • Ratio of by-products to disinfectant was significantly improved by a factor of 2.5 compared to the initial situation, which is sufficient for domestic hot water applications. For the disinfection of drinking water, by-product formation should be further reduced.
  • Electrolytic cells were further developed of to increase efficiency (RF of 5 with ~ 7000 As/m3 or approximately 0.04 kWh/m3), which correlates to an improvement by a factor of 2.5 - 10
  • Efficient electrolysis cells and inline disinfection processes were developed
  • Degradation of anthropogenic trace substances could be verified
