WP 6

Integrated assessment and performance validation

With the view to developing a water purification technology that is also competitive it is necessary to analyse both the financial and the environmental aspects of its further exploitation, including management, safety and regulatory aspects. The new technology has to be competitive both in relation to 1) the environment, where all unwanted emissions have to be taken into account 2) to human health and 3) financial issues. The best approach to assessing the competitiveness of the technology is to combine the environmental LCA, the costs related to technology implementation and the water quality achieved. To ensure that no potential harmful bacteria are introduced into the water supply, all the bacteria have to be confirmed and characterised as non-pathogenic. Downstream UV treatment may still be required by the authorities to eliminate the possibility of bacterial contamination, as is also the case for other advanced water treatment technologies.

BIOTREAT LCA and risk assessment will focus on treatment systems for drinking water resources. Risks of treatment failures related to the developed water treatment technologies will be identified and measures taken to limit the risks. This will ensure that the technologies are stable and reproducible and provide micropollutant removal over long time frames, also at low pollutant concentrations. All pure bacterial cultures and consortia will be characterised and no pathogens or other potentially harmful organisms will be introduced into the water treatment systems. We will also provide specifications as to which specific micropollutants the systems will target and the concentration range for which removal is certain. The competitiveness of the BIOTREAT technologies relative to other water treatment technologies will be determined. This analysis will combine environmental LCA and costs related to technology implementation with the water quality achieved.
