• Nanofiltration is a type of membrane filtration process that uses a membrane with very small pores to separate dissolved solutes from water based on their size and charge. The pore sizes in our nanofiltration membranes are in the range of 0.005 µm to 5 nm, which is smaller than the size of most dissolved ions and molecules but larger than the size of most viruses and bacteria.

    In a nanofiltration process, water containing dissolved solutes is passed through the membrane under pressure. Water molecules that are small enough to pass through the membrane pores are filtered out, while larger dissolved solutes are retained. This separation is based on the size and charge of the solutes, as well as their affinity for the membrane material.

    Nanofiltration is used in a variety of applications, such as water treatment, pharmaceutical manufacturing, and food processing. It is often used as a more effective and selective alternative to traditional filtration methods, such as ultrafiltration or reverse osmosis, which are less selective and require higher pressure to work.

    One of the main benefits of nanofiltration is its ability to selectively remove specific dissolved solutes from water, while retaining others. This allows more precise control over the composition of the filtered water and enables the production of high purity water for a variety of applications.

  • What do we filter?

    Our membrane is made of m-PES, a modified polyethersulfone polymer with very good mechanical and chemical resistance that allows membrane filtration down to 0.005 µm or 5 nm (nanometers).

    • Microbiologically: virus (4 log or 99.99% reduction), bacteria, spores, cysts ... 6 log or 99.9999%.
    • Chemically: reduction of heavy metals, microplastics and nanoplastics, PFAS ...
    • Color, smell, turbidity ...

    Our nanofiltration removes from the water what shouldn't be there but leaves the necessary minerals and salts intact !

    Our filtered water is safe, smooth, tastes great, and is easy on the wallet.

  • Backwash - what is it?

    Membrane filters are of the "hollow fiber" type with an open-ended system. This means that water is pushed through the membrane wall and filtered water flows through the interior. The "dirt" is trapped on the outside of the membrane. By rinsing the membrane regularly , bacteria, viruses, heavy metals, suspended particles, etc. are removed. of the filter... this is called "backwash" from the nanotechnology membrane filter.

  • No electricity

    Our filtration systems do not require electricity, just sufficient pressure . The straw is powered by suction, the bottle is equipped with a built-in pump, and all other systems use normal available water pressure.
