Abstract

A water treatment system centrally communicates and controls one or more water treatment devices to regulate the use of the one or more water treatment devices. The water treatment system is configured to enable a localized, on-demand supply of purified water throughout a building or a network of buildings. The water treatment system may control a degree of purity (e.g., water hardness or concentration of dissolved salts) via mixing of purified and unpurified water streams in a controllable ratio (e.g., via one or more controllable valves or one or more tunable water softening units).

First claim

What is claimed is:

1. A water treatment system for treating water in a building, the water treatment system comprising:
an input pipe;
a first pipe;
a second pipe;
a third pipe;
a water softener device configured to admit an input water stream from the input pipe and to provide first and second outlet streams to the first and second pipes, respectively, the first outlet stream having a first water hardness value of water hardness, and the second outlet stream having a second water hardness value of water hardness;
a regulating device configured to receive the first and second outlet streams from the first and second pipes, respectively, and to provide a third outlet stream through the third pipe; and
a water treatment computer including non-transitory computer-readable medium comprising instructions for treating water that, when executed by a processor, cause the processor to perform the following operations:
receiving an input of a water hardness value of water hardness from a user interface of an appliance or outlet; and
transmitting first control instructions to the regulating device to adjust a ratio of a first flow rate of the first outlet stream relative to a second flow rate of the second outlet stream to provide the water hardness value in the third outlet stream to the appliance or outlet through the third pipe,

the regulating device configured to adjust the ratio of the first flow rate of the first outlet stream relative to the second flow rate of the second outlet stream to provide the water hardness value in the third outlet stream to the appliance or outlet through the third pipe.

2. The water treatment system of claim 1 , wherein the water treatment computer includes a wireless hub.

3. The water treatment system of claim 1 , wherein the receiving and transmitting operations of the water treatment computer are performed wirelessly.

4. The water treatment system of claim 1 , wherein the regulating device includes one or more valves and one or more pumps.

5. The water treatment system of claim 1 , further comprising a sensor configured to sense a sensed hardness value in the third outlet stream, and the processor configured to perform the following further operation: transmitting second control instructions to the regulating device to stop adjusting the ratio in response to the sensed water hardness value.

6. The water treatment system of claim 1 , wherein the appliance or outlet is the appliance, and the appliance is selected from the group consisting of: dishwasher, clothes washer, refrigerator, and steam oven.

7. The water treatment system of claim 1 , wherein the processor is configured to perform the following operations: receiving the input of the water hardness value from the user interface of the appliance or the outlet, transmitting first control instructions to the regulating device to adjust the ratio of the first flow rate of the first outlet stream relative to the second flow rate of the second outlet stream to provide the water hardness value in the third outlet stream to the appliance or the outlet, and the regulating device is configured to adjust the ratio of the first flow rate of the first outlet stream relative to the second flow rate of the second outlet stream to provide the water hardness value in the third outlet stream to the appliance or the outlet through the third pipe.

8. The water treatment system of claim 1 , wherein the first or second outlet streams of the water softener device is a waste water stream.

9. A water treatment system for treating water in a building, the water treatment system comprising:
a water softener device;
a pipe; and
a central water treatment computer including non-transitory computer-readable medium comprising instructions for treating water that, when executed by a processor, cause the processor to perform the following operations:
receiving a user input from an interface associated with an appliance or outlet and indicative of a water hardness value of a water hardness for the appliance or outlet;
transmitting first instructions to the water softener device in response to the water hardness value of the water hardness, the first instructions configured to direct the water hardness device to deliver water with the water hardness value of the water hardness to the appliance or outlet through the pipe;
determining a delivery time to deliver the water with the water hardness value of the water hardness to the appliance or outlet through the pipe; and
transmitting an alert when the delivery time has elapsed; and

the water softener device is configured to treat water according to the water hardness value of the water hardness to obtain first treated water for delivery to the appliance or outlet through the pipe in response to receiving the instructions from the central water treatment computer.

10. The water treatment system of claim 9 , further comprising a sensor operable to receive sensed water hardness data values of the water hardness of water flowing through the pipe.

11. The water treatment system of claim 9 , wherein the central water treatment computer includes a wireless hub.

12. The water treatment system of claim 9 , wherein the receiving and transmitting operations of the central water treatment computer are performed wirelessly.
