TLC-100 Pentair osmotic membrane for reverse osmosis systems. It provides very precise water purification by retaining most dissolved organic and inorganic contaminants, bacteria, and viruses, while reducing the salt compounds responsible for hardness. It is suitable for drinking water and aquarium applications. For longer lifespan, use pre-filters and replace the flow restrictor when changing the membrane.
TLC-100 Pentair 100 GPD is an efficient osmosis membrane designed for use in installations such as a RO filter, reverse osmosis filter, and a complete reverse osmosis system. This component is responsible for the most precise stage of the process offered by reverse osmosis, effectively reducing the amount of dissolved contaminants, salts responsible for hardness, bacteria, and viruses. It is a good choice wherever clean water for drinking, everyday use, and aquarium applications matters.

The Pentair TLC-100 100 GPD membrane has been designed for water treatment systems based on reverse osmosis technology. The membrane is the key component responsible for very precise water purification in a domestic water filtration system.
In practice, this means retaining from 96% to 99.99% of dissolved organic and inorganic contaminants in water, as well as bacteria, viruses, chemical compounds, and heavy metals. Filtration precision reaches 0.001 µm, making the membrane much more precise than standard mechanical or carbon cartridges.
Removing dissolved salt compounds also results in a reduction in water hardness by over 90%. The result is very well purified water, suitable for drinking and also commonly used in aquariums.
The membrane consists of multiple layers wound around a perforated core located inside the element. This design provides a large filtration surface area while maintaining the compact size of the cartridge used in RO systems.
Contaminated water is forced under pressure onto the surface of the membrane. Then water particles pass through microscopic pores, while contaminants are separated and rejected to the drain.
Purified water passes through openings into the central core and, under pressure, flows out of the membrane as filtered water. This operating method makes the membrane the most precise component in the entire reverse osmosis system.
For the osmosis membrane to maintain high efficiency for a long time, it is very important to protect it properly with pre-filters. These are what protect the actual membrane cartridge from faster wear caused by contaminants present in raw water.
The use of pre-filters can extend the membrane's service life to as much as several years. However, actual durability depends on operating conditions and the quality of the feed water.
When replacing the membrane, the flow restrictor installed on the tubing that discharges contaminated water to the sewer must also be replaced.
The membrane service life applies to standard operation and may change depending on the quality of the incoming water and factors such as excessive contamination of well water or a water supply network failure.
The TLC-100 Pentair 100 GPD model works well as a membrane for reverse osmosis filters and systems used to prepare clean drinking water. Thanks to its high filtration precision, it is also used wherever water with a very low content of dissolved contaminants is required, including in aquarium applications.

It is a membrane cartridge for reverse osmosis systems, responsible for the most precise stage of water purification. It removes a wide range of dissolved contaminants and helps obtain water suitable for drinking and aquarium applications.
The membrane retains dissolved organic and inorganic contaminants, bacteria, viruses, chemical compounds, heavy metals, and dissolved salt compounds responsible for water hardness.
Contaminant retention efficiency ranges from 96% to 99.99%, and filtration precision reaches 0.001 µm. Thanks to this, the membrane is one of the most precise components used in domestic water treatment systems.
Yes. The membrane removes dissolved salt compounds, which translates into a reduction in water hardness by over 90%.
Yes, the membrane is suitable both for preparing very well purified drinking water and for aquarium applications.
The most important thing is to use appropriate pre-filters. They protect the membrane from excessive contaminant load and can extend its service life to as much as several years, depending on the quality of the incoming water.
Yes. When replacing the membrane, the flow restrictor located on the tubing discharging contaminated water to the sewer must also be replaced.
Service life is primarily affected by the quality of the feed water and the operating conditions. Shorter durability may occur, among other things, in the case of excessive contamination of well water or a failure of the water supply network.
