Advanced Biology Cascade Schools Back

The Biocoil was a science project first introduced to Cascade by a group of four girls who called themselves the sewage sisters. The biocoil has been running at the High School since 1993. The biocoil is a photosynthetic bioreactor, a sustained system that undergoes photosynthesis and uses nutrients. The biocoil has a very basic design plan: a tank, a pump, clear vinyl tubing, a light source, and chlorella algae with water. The clear vinyl tubing is normally wound around in a “coil” because this makes the space that it fills up as compact as possible. The algae and water are pushed through the tubing by the pump and then splashed into the tank, where the oxygen is released and the CO2 is scrubbed. Lloyd will use our system to provide him the oxygen that he needs.
