Abstract
An apparatus that exposes a biofilm growth surface to liquid media as it rotates. A biofilm growth substratum is wound around a rotatable body in the form of a non-rigid material capable of supporting biofilm growth. A harvester receives the biofilm laden substratum, collects the biofilm as a biomass and reloads the substratum onto the rotatable body.
Claims26
An apparatus comprising:
- a rotatable body contacting a liquid media;
- said rotatable body having a first outer surface which is approximately parallel to an axis of rotation;
- a removable substratum wound around said first outer surface of said rotatable body;
- said substratum configured to support growth of a microorganism biofilm;
- and
- a harvesting device configured to harvest said biofilm from said substratum.
