Abstract
A water filtration system may include a first receptacle configured to store source water, a second receptacle configured to store supply water, an RO filter disposed between the first receptacle and the second receptacle, and a bypass line configured to provide water from the RO filter back to the first receptacle for an initial predetermined amount of time, after which the bypass line is closed and the filtered water is provided to the second receptacle.
Claims14
A water filtration system, comprising:
- a first receptacle configured to store source water;
- a faucet or dispense actuator;
- an RO filter disposed between the first receptacle and the faucet or dispense actuator;
- and
- a bypass line configured to provide water from the RO filter back to the first receptacle for an initial predetermined amount of time, after which the bypass line is closed and the filtered water is provided to the faucet or dispense actuator.
A water filtration system, comprising:
- a first receptacle configured to store source water, the first receptacle comprising an outlet port and an inlet port;
- a second receptacle configured to store supply water, the second receptacle comprising an inlet port;
- a filter system disposed between the first receptacle and the second receptacle, the filter system comprising an inlet port, a first outlet port, a second outlet port, and an RO membrane;
- wherein the outlet port of the first receptacle is disposed in fluid communication with the inlet port of the filter system, the first outlet port of the filter system is disposed in fluid communication with the inlet port of the first receptacle, and the second outlet port of the filter system is disposed in fluid communication with the inlet port of the second receptacle;
- a flow restrictor disposed between and in fluid communication with the first outlet port of the filter system and the inlet port of the first receptacle;
- a first valve disposed between and in fluid communication with the flow restrictor and the inlet port of the first receptacle;
- a second valve disposed between and in fluid communication with the second outlet port of the filter system and the inlet port of the second receptacle;
- and
- a bypass line from the second valve to a location downstream of the flow restrictor.
A method for water filtration, comprising:
- filtering water with an RO filter disposed between a first receptacle configured to store source water and a faucet or dispense actuator;
- and
- initially providing the filtered water from the RO filter back to the first receptacle for an predetermined amount of time.
A method for water filtration, comprising:
- filtering water with an RO filter disposed between a first receptacle configured to store source water and a faucet or dispense actuator;
- and
- adjusting one or more valves to allow water to flow from the RO filter to the first receptacle to reduce a feed pressure on the RO filter between filtration cycles.
