A/O: The dissolved oxygen level in the aerobic tank is too high (8 mg/l); is it possible to use intermittent aeration?
Thread Content
The raw water has a high salt content, so it’s not possible to feed large amounts of water into the system. With a low organic load and high dissolved oxygen levels, is it possible to use intermittent aeration – running the system for a few hours and then stopping it for a while? Will this affect the microbial strains?
In practical operations, there are intermittent cases
