Filmtec 75 GPD reverse osmosis membrane

Reverse osmosis membrane for precise water purification

The Filmtec 75 GPD membrane has been designed for use in reverse osmosis filters. This technology is one of the most precise water treatment methods used in household filtration systems. In practice, this means very high efficiency in contaminant separation and water with significantly better parameters than before filtration.

The membrane retains from 96% to 99.99% of dissolved organic and inorganic contaminants in water, as well as bacteria, viruses, chemical compounds, and heavy metals. Filtration accuracy reaches 0.001 µm, making the reverse osmosis membrane the central element of every effective reverse osmosis system.

An additional benefit is the removal of dissolved salt compounds from water, which results in a reduction in hardness of over 90%. Water purified in this way is suitable for drinking and is also used in aquariums, where high water purity is particularly important.

Key benefits

• intended for reverse osmosis filters and systems,
• highly precise purification of water from dissolved contaminants,
• retention of organic and inorganic contaminants,
• effective reduction of bacteria, viruses, chemical compounds, and heavy metals,
• filtration accuracy up to 0.001 µm,
• removal of dissolved salt compounds,
• reduction of water hardness by over 90%,
• suitable for drinking water and aquarium use,
• possibility of extending service life through the use of pre-filters.

Design and operating principle

The membrane consists of multiple layers wound around a perforated core located inside the cartridge. This design increases the working surface area and effectively enables the separation of water from contaminants.

Contaminated water is forced under pressure onto the membrane surface. Water molecules pass through microscopic pores, while contaminants are separated and discharged to the drain. Purified water passes through openings into the central core and then flows out of the membrane under pressure.

This is the stage responsible for the high purification efficiency for which every high-quality reverse osmosis filter is known. In an RO system, the membrane serves as the main component responsible for the final water quality.

Use and proper membrane operation

For the reverse osmosis membrane to operate effectively and last as long as possible, it should be properly protected by pre-filters. Their role is to limit the inflow of contaminants that could accelerate the wear of the membrane cartridge.

Proper membrane protection through the use of pre-filters can extend its service life even up to several years. However, actual durability depends on operating conditions and the quality of the feed water.

Application

The Filmtec 75 GPD membrane is used wherever effective water treatment is needed in reverse osmosis systems. It is a suitable choice for preparing clean water for everyday consumption, as well as for aquarium applications where stable water parameters are especially important.

In practice, this means it can be used as a cartridge for household RO systems where high filtration accuracy, reduction of salt compounds, and limitation of water hardness matter.
