Abstract: A sea water desalination system and reverse osmosis element for use in a desalination system are provided. The reverse osmosis element includes a body of media material having opposed first and second ends. First and second end cap assemblies are adjacent the first and second ends of the body. A shell of wound composite material encapsulates and retains the body and first and second end cap assemblies together to define an integrated pressure vessel. Methods of assembling are also provided.

Abstract: A housing assembly, portable filter system using the housing assembly and methods of mounting a filter element in a housing assembly are provided. The housing assembly is usable with filter elements of different types. The housing assembly includes a housing body having an open end and being attached to a filter head. The filter head includes a first housing sealing interface configured to sealingly mate with a filter element of the first type and a second housing sealing interface configured to sealingly mate with a filter element of the second type. A cover member removably attaches to the housing body and includes a third housing sealing interface configured to sealingly mate the filter element of the second.

Abstract: An energy recovery system for use in a reverse osmosis system is provided. The energy recovery system has a pair of double headed pistons that reciprocate to pressurize unfiltered water into a reverse osmosis filtration unit. High pressure wastewater from the reverse osmosis filtration unit is used in conjunction with a pump to pressurize the unfiltered water that is pumped to the reverse osmosis filtration unit.
