Take a leap into the
future of pure water.

The tw osmosis membranes: outdo themselves!
A completely Italian, industrialized production, automated and strict quality control in acceptance bring tw reverse osmosis membranes: to have performance and quality always cost.

Reverse osmosis is recognized worldwide as the most effective treatment system compared to microfiltration, ultrafiltration, nanofiltration and ultraviolet treatments; as cited in its study by the Center for Disease Control and Prevention (CDC Center for Disease Control and Prevention). In fact, reverse osmosis is also defined as hyperfiltration due to its great physical and mechanical effectiveness in blocking substances in the water.

Reverse osmosis is a process that uses a semi-permeable membrane for the separation of dissolved salts in the incoming water. That is, thanks to the membrane, the solute is retained, preventing its passage and obtaining a pure solvent at the outlet.

In fact, the CDC (Center for Disease Control and Prevention) in its studies comparing the various water treatments highlights the absolute effectiveness of the osmosis process in removing various microbes.

Reverse osmosis systems are very effective in removing protozoa (for example, Cryptosporidium, Giardia);

Reverse osmosis systems are very effective in removing bacteria (for example, Campylobacter, Salmonella, Shigella, E. coli);

Reverse osmosis systems have very high efficacy in removing viruses (for example Enteric, Hepatitis A, Norovirus, Rotavirus);

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

In conclusion, this CDC study confirms that osmosis is the only highly effective water treatment, even compared to any other treatment, in removing pathogens if present in the water.


As with all tw products: every single 
is subject to strict quality control on entry.

The tw: membranes are then produced by an exclusive and fully automated plant.

This process is therefore free from any human contamination
in order to safeguard an environment in compliance with MOCA food.
Furthermore, throughout the production process, the finished product is continuously subject to in-line quality controls thanks to the power of industry 4.0.

High quality standards!

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

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

This way of proceeding means that the osmosis membranes tw: are a flagship among the membranes now on the market.
