Water Purification Science
We use water every day—rinsing vegetables, cooking, drinking water, or making tea or coffee—without giving it much thought. But while we care for our homes and cars, we often neglect our bodies, focusing on appearance over health. To stay healthy, it's vital that we drink enough (water) and of course the quality of our water is therefore important.
The quality of tap water is a rising issue. Contaminants like agricultural chemicals, pharmaceuticals, hormones, PFAS ("forever chemicals"), heavy metals, and even parasites, bacteria and viruses are increasingly found in our drinking water.
Clean water isn’t a luxury—it’s essential.
In the diagram below you can easily see which contaminants are potentially present in our drinking water. In the grey bar in the top, the size of the particles is shown (ranging from 1000 to 0.0001). The unit of measurement is micrometer (µm). To make things a little more clear, immediately on the left the scale starts with 1000 µm, which corresponds to 1 mm.
The most effective and efficient purification of water is achieved by a multi-stage process. For tap water the first stage focuses on removing small particles.

For purification of tap water, focus must be on removing unwanted contaminations, such as chemicals (amongst which PFAS), hormones, pharmaceuticals and possibly viruses and bacteria.
Ultra-filtration effectively removes bacteria, protozoa, and some viruses from water, making it cleaner and safer.
Nano-filtration goes a step further, eliminating those contaminants plus most natural organic matter and hard water-causing minerals like calcium and magnesium. However, it doesn’t remove dissolved compounds.
For the purest water, Reverse Osmosis (RO) is unmatched, as it removes virtually all dissolved substances, including harmful contaminants like salt and lead, as well as microbes and turbidity. However, RO also removes some healthy minerals, like calcium and magnesium. That’s why our advanced systems include a mineral bed to reintroduce these essential minerals. This not only enhances the water’s health benefits but also balances its pH and reduces corrosiveness, ensuring great-tasting, nourishing water every time.You can read more about our products here.
Nano-filtration uses a membrane with a pore size of approximately 0.001 microns. It effectively eliminates most organic molecules, nearly all viruses, a significant portion of natural organic matter, and various salts. Notably, nanofiltration targets divalent ions, which are responsible for water hardness, making it a common method for softening hard water.
Reverse Osmosis (RO) employs an even finer membrane, with a pore size of about 0.0001 microns. This process produces water that is essentially pure, as it strips away all organic molecules, viruses, and most minerals. As Reverse Osmosis removes even the tiniest ions, it is also suitable for desalinating water.
Reverse Osmosis (RO) is particularly well suited for filtering out even the finest possible contaminants such as viruses and harmful minerals. But where RO removes everything from the water including viruses and bacteria, also trace elements needed by the human body are removed. What is left is pure water. That is why remineralization of drinking water is important.
During post water treatment, essential minerals are added back-in to the water. Re-mineralization of water is beneficial to health making it suitable for long-term drinking.
