Residential reverse osmosis system
A reverse osmosis (RO) system which is capable of producing a permeate flow rate of at least about 25 GPD when the system is operating under a feed pressure of 30 psi.
1. A reverse osmosis system comprising:
means for producing a permeate flow rate of at least about 25 GPD when the system is operating under a feed pressure of 30 psi and a temperature of about 12.7 Celsius without using a pump or carbon filter; and
a housing assembly that contains the means for producing a permeate flow rate of at least about 25 GPD when the system is operating under a feed pressure of 30 psi and a temperature of about 12.7 Celsius, wherein the housing assembly is less than about 380 cubic inches.
2. The reverse osmosis system of claim 1 , wherein the means for producing a permeate flow rate of at least about 25 GPD when the system is operating under a feed pressure of 30 psi and a temperature of about 12.7 Celsius includes a spiral wound membrane element.
3. The reverse osmosis system of claim 1 , wherein the means for producing a permeate flow rate of at least about 25 GPD when the system is operating under a feed pressure of 30 psi and a temperature of about 12.7 Celsius includes means for rejecting at least 90% of chloride ions in a feed flow.
4. A reverse osmosis system comprising:
a housing assembly;
a sediment pre-filter within the housing assembly; and
a membrane element within the housing assembly such that the membrane element receives feed water from the sediment pre-filter, wherein the membrane element produces a permeate flow rate of at least 25 GPD under feed water pressure of 30 psi without using a pump or carbon filter, wherein the housing assembly is less than about 380 cubic inches.
5. The system of claim 4 , wherein the membrane element is a spiral wound membrane element.
