The apparatus comprises a rotor (3), plurality of transverse ribs (6) disposed along the axis (1) of the rotor (3) with a proper spacing between each of said transverse ribs (6) and plurality of longitudinal ribs (7) having the shape of an impeller of a pump, said plurality of longitudinal ribs (7) mounted on each of said transverse ribs (6), said plurality of longitudinal ribs (7) and transverse ribs (6) constituting a biological contactor, thereby causing wastewater to be treated by passing through biological contactor. The longitudinal ribs (7) are obliquely installed in an appropriate angle with the perpendiculars of the exterior tangent arc of the contactor like the impeller of a pump, thereby making wastewater pass efficiently through the space between the ribs (6, 7) with centrifugality by rotation of the rotor (3). |
