Make a leap into
the future of pure water.

The tw: osmosis membranes surpass themselves!
Completely Italian in their industrialised and automated manufacturing,
as well as strict quality control of the incoming materials ensure that the tw: reverse osmosis membranes have performance and quality that is always constant.

According to the study by the CDC (Center for Disease Control and Prevention), reverse osmosis is recognised worldwide as the most effective treatment system when compared to microfiltration, ultrafiltration, nanofiltration and ultraviolet treatments.  Reverse osmosis, is in fact, also called hyperfiltration for its great effectiveness in terms of its capacity of physical and mechanical blocking of substances in water.

Reverse osmosis is a process that uses a semi-permeable membrane for the separation of the dissolved salts in the incoming water. That is, the solute is retained thanks to the membrane, preventing its passage and obtaining a pure solvent in the output.
In fact, in its studies comparing the various water treatments, the CDC (Center for Disease Control and Prevention) highlights the absolute effectiveness of the osmosis process in the removal of diverse microbes.

Reverse osmosis systems have a very high effectiveness in the removal of protozoa (e.g. Cryptosporidium, Giardia);

Reverse osmosis systems have a very high effectiveness in the removal of bacteria (e.g. Campylobacter, Salmonella, Shigella, E. coli);

Reverse osmosis systems have a very high effectiveness in the removal of viruses (e.g. Enteric, Hepatitis A, Norovirus, Rotavirus);

Reverse osmosis systems will remove common chemical contaminants (metal ions, aqueous salts), including sodium, chloride, copper, chromium and lead; they can reduce arsenic.

In conclusion, this CDC study confirms that osmosis is the only water treatment with this degree of effectiveness, even compared to any other treatment, in the removal of any pathogens present in water.

100% manufacturing tw: entirely


As with all tw: products, every single incoming
component is subject to strict quality control.
The tw: membranes are, therefore, produced by means
of an exclusive and fully automated production plant.

This process is therefore free of any human contamination in order to safeguard an environment in MOCA food compliance.

In addition, throughout the production process, the processing is continuously subject
to in-line quality controls thanks to the power of industry 4.0.

The membranes of tw: are made up of


The traditional films on the market are based on polymers, therefore of synthetic origin.

The choice of tw: is that of proposing a completely natural film and, like all the perfect things of nature, able to guarantee exceptional mechanical and chemical stability.

High quality

A rigorous evaluation and control procedure measures the level of conformity of the processed tw: in four areas: dimensional, organoleptic, chemical-physical and performance.

All incoming components and semi-finished products must respond to precise verification procedures according to the specific parameters for quality.

This way of proceeding ensures that the tw: osmosis membranes are the crown jewel among membranes currently on the market.
