The present invention relates to the field of wastewater treatment witch deals with the biological load for bioreactors. The biological load for the bioreactor having a cylindrical shaped housing with an inner surface and an outer surface, said housing comprises of an inner layer having a diameter placed at said inner surface made of a low-density polyethylene with a polymorphic structure; a middle layer to form a supporting frame of the biological load having a gradient porous transition into an outer layer; said outer layer formed by a canvas of polymer filaments made of polypropylene fiber, said canvas formed as a plurality of rowlock arch shaped distributed over said outer surface. The canvas can be used as a component of deep biochemical and biological treatment for domestic wastewater. |
