The scope of sewage treatment is changing: more and more seen as an interface between sanitation and environment, WWTP are delivering resources to the environment and for human activities (e.g. recharge drinking water reservoirs, recycling of nutrient, efficient energy use). This focus shift has implications on the quality goals for WWTP products:

Existing focus:
• nutrient removal
• pathogens removal
• energy optimization
• sludge disposal

New focus:
• nutrient recycling
• micropollutants and ecotoxicity removal
• energy production
• reuse of sludge and of its resources

From November 1 2006 to March 31 2010, NEPTUNE joined 18 partner from Europe, Australia and Canada to focus on
- optimizing wastewater treatment
- developing new technologies
- developing methods for assessing micropollutants and toxicity
- improving life cycle analysis of wastewater treatment as a decision support tool

PROJECT GOALS:

NEPTUNE focused on technology solutions allowing meeting present and future standards via upgrading of existing infrastructure (new control strategies with online sensors; effluent upgrading with oxidation, activated carbon or wetland treatment; sludge processing for safe nutrient recycle) as well as via new techniques (fuel cell applications; new oxidative agents; polymer production from sludge).

By including pathogen and ecotoxicity aspects into life cycle assessment studies (LCA), the project helped to improve the comparability of various technical options and propose a suitability ranking. The new focus given by the WFD and the emerging interest on organic (eco-) toxic compounds requires characterizing treated effluent and treatment technologies concerning ecotoxicologic aspects and micropollutants.
The project contributes to this discussion by ecotoxicity assessment and micropollutan fate studies.
NEPTUNE consists of 6 workpackages, covering different aspects. Within NEPTUNE there is a strong cooperation between the technical work packages WP 1 and WP 2 and the contaminant and toxicity assessment WP 3, in the tasks dealing with the removal and the fate of micropollutants and pathogens. These three WPs provide a major data input to WP 4 for the assessment of environmental sustainability and best practices.

- WP 1: Technologies for WWTP Upgrading to decrease effluent (eco-)toxicity, to optimise nutrient removal and energy consumption and to improve sludge handling and reuse.

- WP 2: Novel Technologies for energy production from wastewater, sludge inertisation, recycling of nutrients and sludge organics, and novel oxidation processes for (eco-)toxicity and pollutant removal.

- WP 3: Contaminant and Toxicity Assessment to evaluate the investigated treatment processes, plant optimisation measures, fate of compounds during treatment, sludge disintegration processes and sludge quality of primary and secondary sludge to improve quality of (secondary) sludge for use in agriculture.

- WP 4: Assessment of Environmental Sustainability and Best Practices of the technologies investigated in WP 1 and 2, including cost/efficiency considerations.

- WP 5: Dissemination Activities with broad involvement and information of stakeholders, regulators, policy makers and Advisory Board members

- WP 6: Coordination and Management Activities


The impact NEPTUNE is going to have can be summarized in two main focuses:
• environmental impact: improving the quality of European water and the efficiency of its management (aquatic environment and drinking water resources)
• economic development: strengthening the competitive position in exporting wastewater technology
Results of Neptune will be used to reduce environmental impact while at the same time reducing overall costs of the environmental protection.
New analytical tools for micropollutants detection will enable better management of the whole effluent toxicity.
By comparing existing as well as new technologies developed within Neptune, using LCA, it will be achievable to find best combination of technologies for each specific demand in WW sector.

Results:
• Technical solutions for upgrading a quantitatively significant water resource: municipal wastewater.
• Options for sludge processing and disposal, allowing to evaluate feasible and safe solutions for nutrient recycle.
• Improved energy efficiency of municipal wastewater treatment.
• Reduced pollutant load discharged into the aquatic environment, by improving nutrient and micropollutant removal and by evaluating wastewater treatment options with new (eco-) toxicological methods.
• Best practice ranking based on life cycle assessment (LCA) and cost efficiency assessment.
• Catalogue with criteria for evaluating technologies
