Abstract
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.
Claims5
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.
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.
