To become competitive, an efficient high-rate reactor system should be simple. For example, introducing waste into the bottom of a UASB reactor or IBR at pressure greater than the head pressure is all that is needed to operate the reactor, providing there is an effective method to separate solids, liquids and gas at the top. The ASBR does not require an upflow pattern and a gas-solids separation system is unnecessary, however it does require equipment and controls for filling, mixing, settling and decanting (Fernandes et al., 1993).
