ABSTRACT:
Apparatus for harvesting converting microorganism cells immobilized on the support discs of a rotary biological contactor. A plurality of cell scraper units are located between the discs and are rotated with the discs while the microorganism cells are growing and performing their converting function. The rotation of the scraper units is then stopped while the discs continue to rotate slowly and the stationary scraper units under controlled pressure scrape the cells off the rotating discs.
