Abstract
Systems and methods for treatment of hard water are disclosed that relate to combining a scale reduction device with a water softener device. In an aspect, the water softener device is an ion exchange water softener device. The systems and methods can be used to provide treated water having the same or similar performance quality compared to water produced by ion exchange water softener devices alone, while using significantly less chemical regenerant.
Claims12
A water treatment system for reducing or eliminating the negative effects of hard water, comprising:
- a water softener device comprising a first inlet for receiving feed water and a first outlet for transferring treated water from the water softener device,
- a scale reduction device comprising a second outlet for transferring treated water from the scale reduction device,
- wherein the scale reduction device is connected to the water softener device via the first outlet, and
- a flow control device connected to the first inlet, wherein the flow control device is configured to direct a first portion of a flow of feed water to only the scale reduction device and a second portion of the flow to both the water softener device and the scale reduction device.
A water treatment system for reducing or eliminating the negative effects of hard water, comprising:
- a scale reduction device comprising a first inlet for receiving feed water and a first outlet for transferring treated water from the scale reduction device, and
- a water softener device comprising a second outlet for transferring treated water from the water softener device, wherein the water softener device excludes a reverse osmosis water softener device,
- wherein the scale reduction device is connected to the water softener device via the first outlet,
- a bypass conduit, wherein an inlet of the bypass conduit is connected to the first inlet and an outlet of the bypass conduit is connected to the first outlet, and
- a flow control valve connected to the bypass conduit, wherein the flow control valve is configured to direct a portion of a flow of the feed water from the first inlet, through the bypass conduit, and into the water softener device via the first outlet.
