Description
SUPREME 75 GPD Osmotic Membrane is a universal cartridge for RO systems, intended for home and aquarium applications. It works well as a component of reverse osmosis-based filters, where effective water treatment, compatibility with standard 12"x2" housings, and stable operation under typical operating conditions matter. It is a practical choice for osmotic filters and water filtration systems designed to provide high contaminant reduction, durability, and easy fitment in most popular RO solutions.

Universal osmotic membrane for RO systems
The ULP75 SUPREME model is an osmotic membrane with standard dimensions, so it fits most devices using reverse osmosis systems. It can be used both in home installations intended for drinking water preparation and in aquarium systems.
Its task is effective separation of contaminants from water. In practice, this means high purification efficiency while maintaining parameters compatible with popular RO installations used as a home water filter or as a reverse osmosis filter for specialized applications.
Main benefits
High filtration efficiency – the membrane retains up to 99% of contaminants, including organic and inorganic substances, heavy metals, and some bacteria and viruses.
Universal compatibility – the standard 12"x2" format allows installation in most reverse osmosis systems available on the market.
For home and aquarium use – one membrane can operate in different RO installations, provided they are designed for cartridges of this size.
Quality control and product identification – each membrane has an individual serial number, which increases purchase security and facilitates quality control.
Long service life – maximum durability reaches up to 6 years, although the actual operating time depends on the level of water contamination and usage conditions.
Water purification performance
The SUPREME 75 GPD membrane is designed for use in RO systems where high separation efficiency is key. It retains up to 99% of the contaminants present in water, which translates into a clear improvement in water quality.
The range of contaminants reduced includes:
organic substances,
inorganic substances,
heavy metals,
some bacteria,
some viruses.
As a result, the membrane is a key element of the water filtration system and supports effective water treatment wherever precise, osmosis-level filtration is required.
Compatibility and application
The cartridge has standard dimensions of 12" in height and 2" in diameter, so it fits most housings used in RO systems. This is a particularly convenient solution when replacing a used membrane in an existing installation.
The membrane can be used in:
home reverse osmosis systems for drinking water,
aquarium RO systems,
popular devices using a standard 12"x2" housing.
The membrane requires the use of a 420 flow restrictor. Chlorine tolerance is 0 ppm, so the cartridge should not come into contact with chlorine. Do not use the membrane for water of unknown origin or microbiologically contaminated water.
Operation and working conditions
To ensure proper operation and maintain high efficiency, the osmotic membrane should be used within the parameters designed for this model. This includes the correct operating pressure, operating temperature, and proper protection against chlorine.
The maximum service life of the cartridge is up to 6 years. In practice, lifespan depends on the quality of the feed water, the level of contamination, and the way the entire reverse osmosis system is used.
In everyday use, this means that a properly selected and correctly operated osmotic filter can work stably for a long time while supporting the performance of the entire RO system.
Why choose this membrane
SUPREME 75 GPD is a cartridge that combines high purification efficiency with a universal installation format. For the user, this means easier system matching, reliable operation in widely used RO systems, and real support for water quality.
It is also a solution that helps maintain the efficiency of the entire filtration system. A properly selected membrane has a direct impact on process efficiency and, as a result, on the convenience of daily use of water purified by a reverse osmosis system.
Using the SUPREME membrane can significantly extend the service life of the RO system, while clean water with reduced levels of many contaminants remains continuously available wherever reliability and repeatable filtration quality matter.

FAQ
Which systems does the SUPREME 75 GPD membrane fit?
The membrane fits most reverse osmosis systems using the standard 12"x2" format. It can be used both in home drinking water installations and in aquarium systems.
What is the performance of this osmotic membrane?
The maximum capacity is 75 GPD, which is up to 280 liters per 24 hours. Actual performance may depend on operating conditions such as water pressure and temperature.
How effectively does the membrane remove contaminants?
The SUPREME 75 GPD model retains up to 99% of contaminants. This includes organic and inorganic substances, heavy metals, and some bacteria and viruses.
Does the membrane tolerate chlorine?
No. Chlorine tolerance is 0 ppm, so the membrane should not operate in contact with chlorine. This is an important condition for maintaining its durability and efficiency.
What restrictor is required for this membrane?
Proper operation requires a flow restrictor, specifically the 420 restrictor.
What pressure and temperature range can the membrane operate in?
The operating pressure range is 2.8 to 6 bar, and the allowable operating temperature is 2 to 42°C.
How long can the SUPREME 75 GPD membrane be used?
The maximum service life is up to 6 years. Actual operating time depends on the level of water contamination and the operating conditions of the entire filtration system.
Is the membrane suitable for any water?
It should not be used for water of unknown origin or microbiologically contaminated water. The membrane should operate in a properly prepared RO system.
What is the purpose of the individual serial number on the membrane?
The individual serial number makes the product easier to identify, improves quality control, and helps reduce the risk of purchasing counterfeits.
