The BER Series offers submersible jet aspirating aerators in varied sizes, available in single-phase or three-phase options. The BER aerator is designed to provide high oxygen transfer and excellent mixing. It is best suited for sequence batch reactors (SBR), where high oxygen transfer is required during aeration and mixing is required during the anoxic cycle when the air is off. It also facilitates intermittent oxidation for the anoxic sludge digestion process.
