An assembly of rotating biological discs are installed on tractors and supported on a shaft forming an entity of various dimensions (diameter - length) which forms a biocylinder which revolves with the aid of an electric reducer and is installed in aeration tanks in effluent and industrial waste processing plants. One such unit (one form) in combination with other similar units of different diameter, length and fixed distance as an entity (biocylinder) achieves the maximum biological surface. It is applied in effluent and industrial waste processing plants. |
