- > ecological sanitation and natural systems for wastewater treatment Baltic Sea’s main problem – EUTROPHICATION – to much nutrients - Main load of nutrients (approx. 70-80 %) come from small and diffuse sources o In Sweden single family-homes contribute with 1/3 of the P-load and 1/10 of the N-load, from all sources in coastal areas (agriculture run-off not included) o In Sweden, with high standard on P-removal in municipal wastewater treatment (approx 90 %) , the next step for cost-effective P-removal is higher standards for single-family homes wastewater o In Finnish coastal municipalities the pollution load from single family-homes can contribute with as much as 80 % of the nutrient load - Big point sources are not the main nutrient contributors to Baltic proper - A strategy to solve Baltic eutrophication must apply effective, long-term sustainable, cost-effective measures for P & N-reduction - Eco-technologies (sustainable systems) often cost-effective for P & N-removal (Conventional treatment in small settlements give low reduction of P & N) - Eco-technologies (sustainable systems) – important component for restoration of the Baltic Sea environment 2009-11-19 World Toilet Day
