We use microfiltration to separate suspended solids from the raw water in order to prevent damage and clogging in the next membrane purification steps. Also, bacterias are being removed by microfiltration.

Dissolved organic matters and chlorine are being removed in this filter. Often the origin of the color and smell of the raw water, dissolved organic matters are being absorbed and chlorine is removed in the active carbon filter. 

The first membrane purification step is the ultrafiltration, in which remaining suspended solids and colloids are removed, as well as all remaining bacteria and viruses that are present in the water.  When starting from a freshwater source, at this point pure drinking water can already be obtained.

The nanofiltration filter removes heavy metals from the water, softens the water and eliminates remaining dissolved organic compounds as well as pesticides/herbicides.

Reverse osmosis (RO) is used to desalinate the entry water, meaning that all ions are removed, and will only be applied for entry raw waters with a high salinity above the WHO drinking water limit (600 mg/L).  

Depending on the salinity of the raw water, high pressures are needed with large corresponding energy consumption. Therefore, in our devices, we focus on maximum energy recovery using the latest robust technologies.

RO is often being applied in the industry (food, textile, chemical, pharmaceutical, etc.) to produce process water for a range of applications such as boiler feed water, brew water,… or water reuse projects.

As our devices produce drinking water, the minerals that were removed in the RO membrane purification step need to be replenished to acquire healthy and tasty water. Therefore, after the RO, a remineralization step is added in our device.

Without the use of any chemicals, our device includes an additional disinfection process based on LED-UV which acts as an additional safety barrier to assure the highest quality of the produced drinking water at all times.

We strongly believe in sustainability, which is why we strongly advise you to use reusable bottles along with our device. We can help in designing one for you.
