Various Biological Membrane Technology

• Biological membrane depends on the operation of the system

• Fixed biological membrane is easy to grow redworm

• Fixed biological membrane process is difficult to control the properties, the thickness of biological membrane also can not be controlled

• Fixed biological membrane system need to increase aeration rate and internally it is mostly

anaerobic

• Sponge carrier system need to squeeze the sludge to let it released

• Plastic carrier is self-regulation, but different carrier, different influences on the diffusion
