Abstract

A water filtering system having its components contained within a single housing. The filter system uses a first filter pair of filters which can be first manually isolated from the water flow; and a second pair of filters which can also be manually isolated from the water flow. The two pairs of filters operate in parallel, thereby allowing one pair to be isolated for cleaning/repair without having to curtail operation since the other pair of filters remain operational.

Claims

1. A water filtering system treating grey water contained in a reservoir for reuse, the water filtering system comprising:

a pump in fluid communication with the reservoir;

a pressure tank in fluid communication with the pump, the pressure tank storing the grey water under pressure;

a housing having an inlet, a first outlet, and a second outlet, the inlet in fluid communication with the pressure tank, the first outlet in fluid communication with an irrigation system, the second outlet in fluid communication with a wastewater disposal system;

a first filter pair contained within the housing, the first filter pair in fluid communication with the inlet;

a second filter pair contained within the housing, the second filter pair in fluid communication with the inlet;

a first valve contained within the housing, the first valve in fluid communication between the first inlet and the first filter pair, the first valve selectively isolating the first filter pair from the inlet;

a second valve contained within the housing, the second valve in fluid communication between the inlet and the second filter pair, the second valve selectively isolating the second filter pair from the inlet;

a first anti-syphon mechanism contained within the housing, the first anti-syphon mechanism in fluid communication between the first filter pair and the outlet, the first anti-syphon mechanism preventing the grey water from flowing in a reverse manner;

a second anti-syphon mechanism contained within the housing, the second anti-syphon mechanism in fluid communication between the second filter pair and the outlet, the second anti-syphon mechanism preventing the grey water from flowing in a reverse manner;

a flow meter contained within the housing, the flow meter in fluid communication between the first anti-syphon mechanism and the outlet and between the second anti-syphon mechanism and the outlet, the flow meter generating a water volume indicia corresponding to the volume of water flowing through both the first filter pair and the second filter pair; and

a third valve contained within said housing, the third valve in fluid communication between the flow meter and the first outlet and between the flow meter and the second outlet, the third valve selectively diverting the grey water between the first outlet and the second outlet.

2. The water filtering system according to claim 1 further comprising an electrical connector contained within the housing, the

electrical connector for communicating electronic signals therethrough.

3. The water filtering system according to claim 2 wherein the water volume indicia generated by the flow meter is electronic, the water volume indicia being communicated via the electrical connector.

4. The water filtering system according to claim 2 wherein the third valve is a solenoid valve responsive to solenoid control signals communicated via the electrical connector.

5. The water filtering system according to claim 1 further comprising a pressure sensor monitoring the pressure within the pressure tank, the pressure sensor selectively activating the pump in response to the pressure within the pressure tank.

6. The water filtering system according to claim 1 further comprising:

a second pump in fluid communication with the first outlet;

a second pressure tank in fluid communication with the second pump, the second pressure tank storing the grey water under pressure, and

an irrigation system in fluid communication with the second pressure tank.

7. The water filtering system according to claim 6, further comprising a second pressure sensor monitoring the pressure within the second pressure tank, the second pressure sensor selectively activating the second pump in response to the pressure within the second pressure tank.
