REVERSE OSMOSIS: THE TECHNOLOGY BEHIND THE CREATION OF LUQEL WATER

The ultimate filtration process

FREE FROM HARMFUL SUBSTANCES

When water is prepared by reverse osmosis, ultra-pure water is obtained that is free from harmful substances. In the follow-up, thanks to LUQEL, it is possible for the first time to mineralise the water according to individual taste. A fully new league of filtration!

OSMOSIS IN NATURE: THE CREATION OF A NATURAL BALANCE

The way osmosis works is strikingly evident on cherries in the rain: The fruit becomes wet and starts to burst. This phenomenon occurs because nature constantly strives to keep a concentration balance between two liquids.

As the rainwater leaves droplets on the cherries, the water molecules penetrate through the skin inside the cherry, where sugar is dissolved  in water. The water in the cherry and the rainwater now try to create a chemical balance between the water and sugar molecules on both sides of the cherry. However, only the significantly smaller water molecules pass through the cherry skin, which acts as a natural membrane. The larger sugar molecules are unable to pass through. As more and more water molecules penetrate into the fruit body, the pressure inside the cherry rises until its skin finally tears.

Reverse osmosis a type of membrane filtration

 

 

REMOVES HORMONES, DRUG RESIDUES AND PESTICIDES

Reverse osmosis is a type of membrane filtration. Only the purest H2O can pass through the membrane, while any substances dissolved in the water and the finest particles are withheld. Any larger foreign substances that need to be filtered can, for example, already be filtered from the untreated water via sediment filtration. For finer substances such as nitrates, drug residues, pesticides or hormones, the reverse osmosis membrane is used.

HOW DOES REVERSE OSMOSIS WORK IN THE TREATMENT OF DRINKING WATER?

For the treatment of drinking water, artificial semi-permeable membranes are produced. This reverse osmosis filter separates contaminated water from water that has already been purified, which no longer contains foreign substances of any type. To filter out the foreign substances, the contaminated water is pressurised at between 4 and 10 bar, allowing only the water molecules but not the foreign substances to penetrate through the membrane.

CORRECT TREATMENT OF WATER AFTER REVERSE OSMOSIS

Although reverse osmosis has the advantage of reliably removing undesired substances, at the same time, it eliminates minerals from the water that are important for humans. At present, the filters based on reverse osmosis available on the market operate on this principle.

LUQEL has fully re-thought out this process and puts the minerals that are essential and affect the taste of the water back, depending on the recipe.

FACTS ABOUT REVERSE OSMOSIS

  • Reverse osmosis is a filtration process that works with a semi-permeable membrane.
  • In the currently available systems, water that is filtered by reverse osmosis is so pure that it hardly contains any minerals at all.
  • Unique: At LUQEL, after filtration water is mineralised according to individual taste.
