In june 2014 the OPTITREAT project kickoff took place in the beautiful vicinity of the research objective The Baltic Sea. For three years research on optimisation of small wastewater treatment facilities will be performed by IVL Swedish Environmental Research Institute, Development and Assessment Institute in Waste Water Technology, RWTH Aachen University Germany  and The Institute for Ecology of Industrial areas, Katowice Poland.

Onsite wastewater treatment is of great concern due to the load of phosphorous and nitrogen contributing to the eutrophication of the Baltic Sea. The load of hazardous substances is of further concern. The consortium of this project will be an optimal cooperation to consider the most important parameters driving the efficiency of the onsite wastewater treatment plants.
