Abstract
Embodiments of the invention provide a method and system for providing a regeneration stage in a water treatment system. The method can include entering a first air bleed state to allow pressurized, deoxygenated air to exit the water treatment system, entering a second air bleed state to equalize a first air pressure of remaining deoxygenated air inside the water treatment system with a second air pressure outside the water treatment system, entering a backwash state to expel remaining deoxygenated air and particulates from inside the water treatment system, and entering an air draw state to allow oxygenated air to enter the water treatment system.
