RO Membrane Housing – Safe, Non-Toxic, Stable & Durable

The RO membrane housing is an important component in reverse osmosis water purification systems, primarily used to secure and protect the RO membrane filter element, ensuring its stable operation under high-pressure conditions. The housing design includes an inlet, a pure water outlet, and a concentrated water outlet, providing separate flow paths for raw water, purified water, and concentrated water to prevent water pollution.

The RO membrane housing comes in a full range of specifications, compatible with different sizes of RO membrane filter elements (such as 50–800 G), suitable for various specifications of home RO water purifiers and commercial RO water purifiers, among others.

Structure

Water inlet. It connects to a high-pressure water source, with common connector specifications including 1/4" or 3/8" quick-connect and threaded connectors.
Housing end cap. It seals and protect the filter cartridge.
Brine seal. It ensures that water flows through the RO membrane filter cartridge according to the designed path.
RO membrane. It is used to remove heavy metals, bacteria, viruses, and other small pollutants and harmful substances from water.
Membrane housing. Made of high-quality plastic material, it ensures long-lasting durability.
O-ring. It ensures a tight seal in the water system to prevent water leakage under high-pressure conditions.
Membrane housing inner annulus. It secures the RO membrane filter element.
Pure water outlet. Drinkable pure water flows out from this outlet.
Wastewater outlet: Filtered wastewater is discharged from this outlet.
