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.
Claims6
A method of providing a regeneration stage in a water treatment system, the method comprising:
- providing a powerhead and a valve assembly, the valve assembly including a piston assembly;
- pressurizing a tank by the addition of water;
- operating the piston assembly in the valve assembly to enable the water treatment system to enter a first air bleed state for a first time period to allow pressurized, deoxygenated air to exit the water treatment system;
- operating the piston assembly in the valve assembly to enable the water treatment system to enter a second air bleed state for a second time period to equalize a first air pressure of remaining deoxygenated air inside the water treatment system with a second atmospheric air pressure outside the water treatment system;
- and
- operating the piston assembly in the valve assembly to enable the water treatment system to enter a backwash state for a third time period to expel the remaining deoxygenated air and particulates from inside the water treatment system.
