The intention is to improve nitrogenreduction and to eliminate and alanyse toxic substances in waste water with a process containing plants and micro organisms.To create new jobs, to educate and to strenghten network with industrial life.To make waste water treatment popular via "tourism".METHODS: Introduce water hyacints to conventional treatment.At sedimentation of fine kolloidals the plants act as adsorbers.The fine particles are enriched at the plant roots.Regular water chemistry analysis are taken by authorities.Biomass analysis of elements are done with ICP_MS.Toxic elements of organic origin are analysed by HPLC.Some bacteriologic analysis must be performed to secure that the biomass can be recycled.
