TFC-75F Aquafilter 75 GPD reverse osmosis membrane

Osmosis membrane for precise water purification

Aquafilter TFC-75F 75 GPD is a membrane intended for filters using the reverse osmosis process. The membrane is the heart of the RO system and is responsible for the most precise filtration stage in the entire water filtration system.

In practice, this means very high efficiency in removing contaminants dissolved in water. The membrane retains from 96% to 99.99% of organic and inorganic contaminants, as well as bacteria, viruses, chemical compounds, and heavy metals. Filtration accuracy reaches 0.001 µm, which means the purified water can be used both as drinking water and in aquarium applications.

Key user benefits

• designed for reverse osmosis systems,
• very precise water purification in household and specialist applications,
• retains from 96% to 99.99% of dissolved organic and inorganic contaminants,
• reduces bacteria, viruses, chemical compounds, and heavy metals,
• filtration accuracy at the level of 0.001 µm,
• removal of dissolved salt compounds,
• water hardness reduction by over 90%,
• water suitable for drinking and aquarium use,
• service life can be extended up to several years when pre-filters are used.

How the TFC-75F membrane works

Membrane structure

The membrane consists of many layers wound around a perforated core located inside the cartridge. This design provides a large filtration surface area while maintaining compact dimensions of the working element.

Operating principle

Contaminated water is forced under pressure onto the surface of the membrane. Water molecules pass through microscopic pores, while unwanted contaminants are separated from the clean water stream and directed to the drain.

Purified water passes through openings into the central core and then flows out of the membrane under pressure. Thanks to this, the osmosis filter can provide water with a very high degree of purity, far exceeding the capabilities of standard mechanical methods.

Impact on water quality

The Aquafilter TFC-75F osmosis membrane reduces the content of dissolved salts in water, which directly translates into a hardness reduction of over 90%. This is especially important for users who want to improve the taste and parameters of drinking water or prepare water for more demanding applications such as aquariums.

Combined with properly selected pre-filter cartridges, the membrane creates an effective water treatment system that helps reduce the presence of many problematic substances found in tap water or water from other sources.

Operation and replacement recommendations

For proper membrane operation and to maintain high filtration efficiency, appropriate protection by pre-filters is very important. They capture contaminants that could accelerate membrane wear and reduce its performance.

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

Application

• reverse osmosis systems for preparing drinking water,
• household water filtration systems,
• systems requiring salt reduction and lower hardness,
• aquarium applications where very well-purified water is needed.
