20140144845 | METHOD FOR WATER TREATMENT REGENERATION STAGE - 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. | 05-29-2014 |
20140076813 | TWIN TANK WATER TREATMENT METHOD - Embodiments of the invention provide a twin tank water treatment system and method. The water treatment system includes first tank with a first set of sensors and a first resin bed, a second tank with a second set of sensors and a second resin bed, and a valve assembly with a flow meter and a controller in communication with the first set of sensors, the second set of sensors, and the flow meter. The method includes determining when the resin beds are exhausted based on input from the flow meter, the sensors, and a water hardness setting. | 03-20-2014 |
