Rotary biological flow-through filter |
| abstract |
Secondary treatment for comminuted, screened or clarified sewage. The sewage is supplied to a filter assembly consisting of a rotating pair of flanges, one blank and one perforated, with arcuately shaped filter elements sandwiched between the flanges. By providing a large surface area for the filters and making them of a material to which slime will adhere, biological treatment is obtained. Further, the assembly rotates in the atmosphere providing air without aeration equipment enhancing the aerobic biological purification process. |
