Aeration control valve system for water treatment system and methods for using same

摘要

An aeration control valve system may be used with a water treatment system to control aeration and flow of water in accordance with various operating cycles. The aeration control valve system causes air to be pumped or drawn into the water treatment system during an air charge cycle to provide an air charge for aerating the water to facilitate water treatment. The aeration control valve system releases the air during an air release cycle without requiring a backwash cycle. In one embodiment, the aeration control valve system includes a control valve unit configured for connection to a brine tank but instead fluidly coupled to an air intake inlet and an air release outlet for supplying and releasing air, respectively, when the valve cycle actuator is in the brine position and brine tank fill position, respectively.

主权项

1. An aeration control valve system for use with a water treatment tank, the aeration control valve system comprising:
a supply water inlet passage configured to receive water from a water supply; a service water outlet passage configured to direct water to a service water system; first and second tank passages configured to direct water in to or out of the water treatment tank; an air passage fluidly coupled to the first tank passage and configured to allow air to pass to and from the first tank passage such that air release and air intake is provided through a single connection to the air passage; a drain outlet passage configured to direct water from the water treatment tank to a drain; an air intake inlet fluidly coupled to the air passage and configured to supply air to the air passage; an air release outlet fluidly connected to the air passage and configured to release air from the air passage; a valve cycle actuator configured to provide fluid connections between the passages based on different positions of the valve cycle actuator during different operation cycles; and an air valve configured to allow air to be released from the water treatment tank into the air passage to the air release outlet.
