8. Naturewater Reverse osmosis system NW-RO400-E2

With the Naturewater reverse osmosis system NW-RO400-E2, you get clean water straight from the tap. To do this, the water is pressed against a membrane inside the reverse osmosis system and only pure water (permeate) passes through it. The dissolved minerals and pollutants are not allowed to pass through the membrane and are discharged with the residual water (concentrate). This method is not only effective, but also cost-effective.

Experience a completely new flavour of pure water. This type of water treatment is not only suitable for drinking water, but can also be used for aquarium water and wherever you need demineralised water.

Reverse osmosis is a natural process that does not require any chemicals. The dissolved salts and pollutants are safely removed from the water by purely physical means.

The membrane booster pump integrated into the reverse osmosis system increases the pressure within the filter system and improves the quality of the water produced. However, the quantity and quality of the osmosis water also depend on the pressure and temperature of the raw water.

The system can filter up to 1500 litres per day and removes up to 99% of foreign substances such as heavy metals, pesticides, hormones, fungicides, pharmaceuticals, nitrate, phosphate, chlorine, asbestos, lime, radioactive isotopes, bacteria, protozoa, cysts, algae, spores, etc. from the water.
