Presentation Transcript

  1. Classification by temperature • Psychrophiles • grow at temperatures below 25°C. • Mesophiles • grow at temperatures between 25 - 45°C. • Thermophiles • grow at temperatures between 45 and 60°C.

  2. Classification by growth environment • Suspended growth • Activated sludge • Attached growth • Trickling filter • Rotating biological contactor

  3. Ten Growth Requirements • Carbon source • Energy source • Terminal electron acceptor • Macro nutrients: C, N, H, O, P, K, S • Micro nutrients: Fe, Ni, Co, Mb, Zn, etc.
