Apparatus for support-immobilised waste water purification

摘要

The invention relates to an apparatus for the biological purification of waste water (effluent) in a reactor 3, in which are arranged support material elements 4 made of open-pored plastic foam as a growth surface for biomass. According to the invention, it is proposed to design the support material elements 4 in such a way that they have a baseplate 1 from which project longitudinal bodies 2. <IMAGE>
