Abstract
A tankless reverse osmosis system which is capable of producing a permeate flow rate of at least 500 GPD when operating under home reverse osmosis conditions.
Claims43
A tankless reverse osmosis (RO) system which is capable of producing a permeate flow rate of at least 500 GPD when the system is operating under home reverse osmosis conditions and is dimensioned to fit within a standard kitchen sink cabinet.
A system, comprising;
- an inlet to receive feed water;
- a pre-filter coupled to the inlet to receive the feed water, the pre-filter having an outlet;
- a membrane element to receive the feed water from the outlet of the pre-filter, the membrane element having a permeate output and a concentrate outlet;
- and
- a faucet to receive filtered water from the permeate outlet, wherein there is not an intervening storage tank between the membrane element and the faucet;
- wherein the membrane element is capable of producing a permeate flow rate of at least 500 GPD under home reverse osmosis conditions and wherein the membrane element is enclosed within an assembly dimensioned to fit within a standard kitchen sink cabinet.
3 more elements
A system, comprising:
- an elongated assembly having a first end and a second end;
- an inlet on the assembly to receive feed water;
- a pre-filter member communicating with the inlet to receive the feed water from the inlet;
- a first membrane element communicating with an outlet of the pre-filter to receive the feed water from the pre-filter member, the membrane element having a concentrate outlet and a permeate outlet;
- a first outlet on a surface of the assembly and communicating with the permeate outlet of the membrane element;
- a second outlet on a surface of the assembly and communicating with the concentrate outlet of the membrane element;
- an endcap on one end of the assembly which covers one end of the pre-filter member and one end of the membrane element;
- and
- a single endcap retaining member for removably mounting the endcap to the assembly.
6 more elements
A system, comprising:
- an elongated housing assembly having a molded structure including a cylindrical pre-filter chamber oriented longitudinally within the assembly and a cylindrical membrane element chamber oriented longitudinally within the assembly and a permeate flow tube running longitudinally through the assembly and a concentrate flow tube running longitudinally through the assembly;
- an inlet on a first end of the assembly to receive feed water;
- a pre-filter member located within the pre-filter chamber and communicating with the inlet to receive the feed water from the inlet;
- and
- a membrane element located within the membrane element chamber and communicating with an outlet of the pre-filter to receive the feed water from the pre-filter member, the membrane element having a concentrate outlet and a permeate outlet, wherein the permeate outlet is connected to a first end of the permeate flow tube and wherein the concentrate outlet is connected to a first end of the concentrate flow tube.
2 more elements
A system comprising:
- an assembly;
- a pre-filter member within the assembly to receive feed water from a water line;
- and
- a pair of membrane elements located within the assembly and connected in series to receive the feed water from an outlet of the pre-filter member;
- wherein the pair of membrane elements include permeate outlets and concentrate outlets, wherein the permeate outlets are connected to a faucet;
- wherein the pair of membrane elements are adapted to produce a permeate flow rate of at least 500 GPD when operating under home reverse osmosis conditions.
3 more elements
A system comprising:
- a manifold including one or more threaded sockets;
- one or more cartridge housings removably attachable to the threaded sockets;
- and
- a base leg including one or more cartridge holding portions to support a distal end of each of the one or more cartridges, wherein at least one of the cartridge holding portions as adapted to engage an outer portion of each of the one or more cartridge housings such that the at least one cartridge holding portion can be used to either tighten or loosen the cartridge housing from one of the threaded sockets.
1 more element
A system comprising:
- a housing assembly for holding one or more membrane elements, the housing including an inlet port, and two outlet ports;
- a connector for connecting outside tubing to the inlet and outlet ports, the connector including a plurality of members each having a first end connectable to a hose and a second end for connecting to one of the ports;
- and
- a key configured to hold the connector members in position on the inlet and outlet ports.
