Abstract

Short rotation willow plantation for wastewater purification: case study at Aarike, Estonia V. Kimsemets*, K. Heinsoo^, E. Sild^ & A. KoppeP * Institute of Geography, University of Tartu, Estonia * Institute of Zoology and Botany, Estonian University of Agricultural Sciences Abstract A small pilot willow plantation was established to study the possibilities of usage of willows for biomass production and wastewater purification. The wastewater f* from a dwelling house (25 p.e.) is treated on an 180m surface - subsurface flow constructed wetland. The wastewater is flowing in serpentine ditches through three basins on which beds with filter media are planted with willows (Salix viminalis and Salix dasydados). The system showed high wood productivity and also high wastewater purification efficiency. The average annual plant wood dry matter production for the second rotation period was 1.16 kg, which exceeded the productivity in the fe
