The importance of pure water

Pure water is essential for life on our planet. Everyone should have access to pure and healthy water!

Our drinking water is regulated at the state level to protect people's health. The Drinking Water Ordinance guarantees that tap water is free of pathogens and harmful substances. It should be free of suspended matter, odor, and coloration. It is the most strictly controlled food in Germany. In comparison, the regulations for mineral and table water are more relaxed, although we often pay extra for bottled water.

Challenges in the household

But the water that comes from our taps isn't always as pure as we think. On its way to our homes, it can absorb contaminants that simply boiling can't remove. There are up to 2,000 different possible contaminants that can find their way into our drinking water.

Tap water and its dangers

• Heavy metals such as lead, arsenic and uranium, some of which are radioactive
• Residues of medicines such as antibiotics and hormones that enter the water cycle via wastewater
• Pesticides, herbicides and nitrates from agricultural use, which can convert into harmful nitrite in the body
• Chlorine and chlorides, which are used for disinfection but can cause taste changes

To minimize these risks, installing a reverse osmosis system or a high-quality water filter is a good idea. These can help effectively remove unwanted substances and contaminants, giving you access to pure water.

Make your own osmosis water - clear, soft and healthy

The term "osmosis water" has been known in the aquarium hobby for a long time. This type of water, produced in its purest form, is very popular for keeping fish healthy. For decades, more and more people have preferred the particularly pure osmosis water for drinking water for health reasons. You can produce this particularly pure osmosis water yourself at home using a reverse osmosis system from your tap water. There are no limits to the applications of osmosis water. Wherever pure water is needed, you can use osmosis water with the best results.

Application of osmosis water

You can use osmosis water for drinks, cooking, preparing baby food, making coffee and tea, for fully automatic coffee machines, for facial and skin care, for shaving, as drinking water for your pets, for watering plants, for making ice cubes, for using steam cleaners, for humidifiers and for your aquarium, for film development, for your car's wiper and washing system and much more.
Osmosis water has many possible uses in the home or for your hobby. Furthermore, this pure water is free of limescale and protects all your household appliances from unsightly limescale and dirt. You will get more enjoyment from your appliances, such as your steam iron, kettle, coffee maker, indoor fountain, etc. Also worth noting is the cleaning power of pure water for surfaces, such as windshields, ceramic hobs, mirrors, window panes, the display of your smartphone, and so on. This also extends the lifespan and maintenance intervals of your appliances. In the future, you can easily and conveniently draw your own pure water directly from your own reverse osmosis system at home and enjoy the many benefits of fresh, pure osmosis water. We would be happy to advise you and look forward to hearing from you.

Healthy pure water

Once you and your family discover the fresh, thirst-quenching taste of pure water, you'll see this essential ingredient in a whole new light. With pure drinking water from a reverse osmosis system, you're consuming exceptionally pure and healthy water—water in a pure, uncontaminated form, free from any contaminants.

Soft, lime-free water for coffee, tea, fruit spritzers & other drinks

"Just add water," is the motto in many preparations. By using pure water, you're adding water without any unpleasant taste or impurities. Coffee and tea, in particular, taste better than ever with reverse osmosis water. Why? You only taste the coffee or tea, not the salts and metallic compounds that come with tap water, which, for example, make coffee bitter and sour. In addition, coffee or tea can develop its full aroma better. Have you heard that?

Fresh, 100% fruit juices with no added sugar are healthy and rich in vitamins. However, these 100% fruit juices often still contain a lot of fructose and, consequently, a lot of calories. To reduce calorie intake, you can easily make a healthy, light fruit juice spritzer using reverse osmosis water. Simply mix your 100% fruit juice with the reverse osmosis water. At the same time, any fruit acid present is also reduced. This makes a fruit juice spritzer more pleasant to drink and easier to digest. Foodies will quickly notice the difference.

Preparing baby food

"Just add water," is the message in many baby formula or baby food packages. Pure osmosis water is ideal for the healthy preparation of baby food and is particularly suitable because it is free of nitrates, heavy metals such as lead, copper, etc., drug residues, pesticides, and many other contaminants, and also contributes to a low-sodium diet for babies. Give your baby uncontaminated water from the very beginning, whether as tea, to dilute fruit juices, or as pure water to drink. Safe and healthy from the start.

Cooking and preparing food

Pure water has a wide range of uses, including preparing food and beverages for a pure taste (soups, sauces, vegetables, tea, coffee, etc.). Ordinary tap water with chemical additives such as chlorine, salts, and inorganic contaminants impairs the taste of vegetables, soups, sauces, and all foods cooked in water. From now on, cook only with pure water and taste the difference. When you cook with pure water, you'll also be pleased to see that your pots, coffee maker, and kettle no longer develop limescale.

Clear ice cubes with osmosis water

Make your ice cubes only with reverse osmosis water. You'll be amazed at how clear your ice cubes are—no more white inclusions, and the taste of your drinks will always be consistent.

Support for a diet with pure osmosis water

Many mineral salts in tap and mineral water bind water in the body. The more salt you consume, the more excess weight you carry around. Osmosis water supports any diet by eliminating these unnecessary ingredients. If you've previously made your drinks with tap or mineral water, you should try the following: Drink two to three liters of osmosis water for a month without changing your diet. See if you can celebrate losing a few pounds. No other water has this effect!

Pure water for facial & skin care

Your skin will also thank you for your osmosis water care. The clean water deeply cleanses the skin and gives it a radiant, fresh appearance with a firm surface. Water replenishes the skin's layers and makes you look years younger.

Delicious soft water ideal for your pets and aquariums

Animals instinctively know which water is good for them. Try it out: Set up two bowls, one with tap water and one with reverse osmosis water. You'll see, your pet will choose reverse osmosis water. This pure water is also very tasty and odorless for animals. Animals are true gourmets and incorruptible.

Pure water is ideal for aquariums . Reverse osmosis and water filters are used in aquariums. They are used for aquarium inhabitants and plants with particular demands for the high quality of pure, uncontaminated water. Your fish in the aquarium thrive in a mixture of osmosis water and tap water. This mixing is also called blending. Pure water makes aquarium water softer because it is free of limescale and also free of contaminants. Take a look at your bottle of aquarium water optimizer; then you'll know what contaminants can be found in tap water! After all, the water optimizer must neutralize precisely these contaminants in tap water before the water can be called aquarium water.

Water your plants with pure water for better growth

Osmosis water is an ideal solvent for plants to draw nutrients from the soil. Water your plants with osmosis water and watch them grow and thrive. You'll be amazed. Everyone will envy your magnificent plants.

Demineralized water for humidifiers - limescale-free

Humidifiers and air purifiers release water into the air. Almost all devices quickly develop unsightly deposits, such as limescale or rust. This encrustes the mechanism and ultimately destroys it. With demineralized water, you won't have this problem. Your devices, such as humidifiers, indoor fountains, water-cooled air conditioners, etc., will remain limescale-free and thus stay like new for longer.

Lime-free water for windscreen washer & car care

What driver would ever think of filling their windshield washer system with purified water from an osmosis system? But try it, and you'll never use any other type of water for your windshield washer system again. With osmosis water, you won't have streaks on your windshield, and the spray water that runs off won't leave marks on the glass or paint. Even modern car washes use osmosis water for cleaning. Wash your car with osmosis water. Osmosis water won't leave streaks or even limescale stains on your car. The car paint, as well as the windshield and rear window, will be free of limescale deposits. The car paint will shine, and the clean windows will ensure a clear view.

Membrane technology

How does reverse osmosis work

Reverse osmosis is a water filtration process based on the principle of osmosis. Here are the basic steps of how reverse osmosis works:

Osmosis: First, it's important to understand what osmosis is. In osmosis, water molecules move through a semipermeable membrane from a solution with a lower concentration of solutes (e.g., salts) to a solution with a higher concentration to reach equilibrium.

Reverse osmosis: In reverse osmosis, this natural process is reversed. By applying pressure to the concentrated solution (e.g., tap water), the water is forced through the semipermeable membrane. This membrane allows only water molecules to pass through, trapping larger molecules, ions, and contaminants (such as heavy metals, salts, bacteria, and other pollutants).

Filtration: The water that passes through the membrane is called "purified water" or "permeate." The water that does not pass through the membrane is called "concentrate" or "effluent" and contains the trapped contaminants.

Post-treatment: After reverse osmosis, the purified water is often passed through additional filters (e.g. activated carbon filters) to improve taste and odor.

Storage: The filtered water is stored in a water tank from where it can be drawn when needed.

Reverse osmosis is an effective method for producing pure water free from many contaminants and is widely used in households, industry, and aquariums. If you have any further questions or would like more details, I'm happy to help!

The principle of reverse osmosis has been the best and most cost-effective method for producing pure and healthy osmosis water for over 60 years. For decades, the principle of reverse osmosis has been successfully used wherever pure water is needed, such as in medicine, pharmaceuticals, the food industry, on ships and in space travel, etc. Below, we explain the function of the reverse osmosis membrane.

Water treatment, pre-filtration in osmosis systems

The tap water (raw water) is treated in the pre-filter system. The 5µm sediment filter (1st stage) removes coarse particles such as sand, rust, limescale, suspended matter, etc. The 5µm activated carbon block filter (2nd stage) removes chlorine and organic contaminants. It also filters out suspended and flavored substances and organic contaminants dissolved in the water. The 1µm sediment filter (3rd stage) removes particularly fine particles and suspended matter and protects the membrane from any activated carbon dust that may be present. Depending on the system and requirements, other pre-filters can also be combined and used.

Reverse osmosis membrane technology

Filtration in the pre-filter system increases the purification level in the subsequent membrane filtration technology (4th stage) and extends the lifespan of the membrane. The tap water (raw water) is pressed against a synthetic, semi-permeable membrane with a pore size of only 0.0001 µm, which is permeable only to water molecules and not to impurities in the tap water (raw water). Therefore, only clean, pure water collects on the other side of the membrane. The impurities are flushed away and drained directly into the drain. The pressure of the tap water is sufficient to force the water through the membrane. The membrane is the heart of a reverse osmosis system. This removes almost all harmful substances and flavors, such as bacteria, viruses, germs, hormones, antibiotics, drug residues, pesticides, herbicides, fungicides, lead, arsenic, sulfur, lime, radioactive substances, nitrate and almost all other harmful substances.

The retention rates of various substances in a TFC membrane (plastic) made of polyamide-polysulfone (measured by electrical conductivity)

All molecules larger than the 0.0001µm water molecule are retained by the reverse osmosis membrane. The larger the molecule, the better it can be removed from the water. Heavy metals, for example, have a very high retention rate due to their size. Complex molecular structures such as hormones, viruses, drug residues, etc., are almost completely removed from the water. X-ray contrast media, if used in the form of an aqueous suspension of barium sulfate (BaSO4) (water-insoluble), or as iodine in the form of a triiodinated benzene ring (water-soluble, ionic/non-ionic), or in an oily (water-insoluble) compound, are also almost completely removed from the water.

Post-filtering

All of our reverse osmosis systems are equipped with an activated carbon post-filter or (activated carbon post-filter & combination filter), which filters the purified water again before use and ensures a pleasant and neutral taste.

Mineralization / Vitalization

Optionally, any reverse osmosis system can be upgraded with a mineral filter, energizing filter, or vitalizing filter. Depending on the selection, these contain one or more filter media with different compositions. These create agitation in the water. Depending on the type of filter, the water is mineralized, energized, or vitalized. Trace minerals are added, significantly improving the water density, ionization, conductivity, surface tension, and, above all, the pH value. The water acquires a natural and invigorating taste.

Dependencies for osmosis water performance

The maximum performance of a reverse osmosis membrane is specified at approximately 20°C. At lower water temperatures, the purified water (osmosis water) performance decreases. This occurs, for example, in the winter months. For every 1°C lower than 20°C, the purified water performance decreases by 4%. The membrane fabric contracts at low temperatures, allowing less purified water (osmosis water) to pass through. This can increase the amount of wastewater. The purified water quality is improved at lower water temperatures.

Test your water with a TDS meter

We recommend our TDS meter. This device allows you to measure conductivity. It measures the total dissolved solids (mobile ions, including minerals, salts, and metals) in a specific volume of water, expressed in mg per volume of water (mg/L), also known as particles per million (ppm). Filtered water has an optimal concentration of approximately 10-20 ppm. If the concentration exceeds 60 ppm, the filters should be replaced. For comparison, normal tap water has a conductivity of approximately 200-500 ppm and higher.

What does pure water – osmosis water – taste like?

Osmosis water itself has a naturally neutral taste . However, this taste can be perceived differently. Therefore, the same glass of osmosis water can taste sweet to one person, sour to another, and bitter or metallic to yet another, as the filtered and neutral osmosis water is an excellent flavor carrier. This different perception of taste does not indicate a defect in the osmosis system; rather, when you taste this osmosis water, you are primarily tasting yourself.

Within a household with different people, you can see that the taste of osmosis water is perceived differently, so you can see that it is not the osmosis water that contains the taste, but that the differences lie between the different people.

Taste perceptions can vary

If the osmosis water is perceived as sweet or neutral, that's normal. If the osmosis water is perceived as acidic, then your body may be over-acidified. If the osmosis water is perceived as bitter, this could be an indication of problems with the digestive tract, liver, or gallbladder. If the osmosis water has a metallic taste, this could indicate elevated levels of heavy metals, for example.

In this case, osmosis water acts like an indicator and can point to existing problems in the body. This property of osmosis water is to be viewed as positive, as it provides an indication for significant improvement in specific areas of the body through targeted measures.

Most people who drink osmosis water find that after a few weeks, the initial taste perceptions diminish or disappear completely. In this case, after an adjustment period, the body registers that toxins and harmful substances can now be released from the body into the water, as the osmosis water serves as a transport medium and can absorb more pollutants than regular tap or bottled water.

Experience shows that after several weeks or months, the body has released most of the unwanted stored toxins from the body and thus the unusual taste sensation diminishes and disappears completely. This means that osmosis water also undergoes a kind of purification and detoxification treatment.

Filter change of pre-filter, activated carbon post-filter and mineral filter

To ensure consistently high water quality in your reverse osmosis system and water filter, the pre-filters and post-filters should be replaced regularly.

The recommended replacement interval for the pre-filter and post-filter in reverse osmosis systems and water filters is approximately every 6 months² for medium water quality (depending on the degree of contamination, pollutant load, and water hardness), or when the pure water value exceeds 60 ppm (93 µS). Whichever occurs first is relevant. This recommendation assumes normal household use , not industrial use , and not use with extremely high water consumption , e.g., for large aquariums.

• Recommended filter change: every 6 months² with normal household use and an average tap water of approx. 250 ppm .
• If you have a high water consumption, e.g. for water changes in a large aquarium, it is necessary to change the filters earlier and more often.
• In case of high usage (e.g. aquariums) or poor water quality on site, a filter change is recommended: every 3-4 months².

²The filter replacement interval depends on the water quality of the raw water. This factor influences the lifespan of the filters and the membrane. Therefore, recommendations are based on average drinking water quality in Germany.

Water hardness for reverse osmosis systems and water filters

The higher the dH value, the harder the water. There are uniform regulations in Germany regarding when water is considered soft or hard. Up to a measured value of:

• 8.4 °dH the water is considered soft
• from 8.4 °dH to 14 °dH as medium and
• from 15 °dH accordingly as hard

For reverse osmosis systems, raw water of medium hardness °dH is recommended.

Recommended filter change

• You can find new replacement filters in a set here.
• Of course, you can also purchase each filter individually from us.
• You can purchase Atlas Filtri replacement water filters here.
• You can also purchase mineral filters from us.

Disinfection of reverse osmosis systems and water filters

We recommend performing a thorough disinfection of the reverse osmosis system or water filter every time you change the filter. With knick'n'clean aqua, we offer a highly effective disinfectant for water filters, reverse osmosis systems in the home, boats, and caravans. knick'n'clean® aqua can also be used to directly disinfect up to 500 liters of drinking water.

Recommended membrane change

The reverse osmosis membrane is the heart of the reverse osmosis system, where the actual water separation process takes place. Our systems use only high-quality, long-lasting TFC membranes. The membranes should also be replaced regularly. The replacement time depends on the water quality and the flow rate already achieved.

• 50 GPD membrane: approximately every 12 months² (GALANT, Elegance 1, Elegance 2, Quella Nova or similar systems)
• 50 GPD - 75 GPD membrane: approx. every 12-24 months²
• 85 GPD membrane: approximately every 12-24 months (ROPOT, Elegance 3, Quella Viva or similar systems)
• 125 GPD - 200 GPD membrane: approx. every 12-24 months²
• 300 GPD - 400 GPD - 500 GPD - 600 GPD - 800 GPD Membrane: approx. every 36-60 months²

²Depending on flow rate and local water quality.

Depending on the model, a reverse osmosis system is equipped with a manual flush valve (optional). This flush valve allows you to flush the membrane and thus extend its service life. We recommend opening the manual flush valve every 14 days for approximately 10-15 minutes to flush the membrane. If your reverse osmosis system does not have a flush function, a manual flush valve can be retrofitted.

Maintenance of reverse osmosis systems

Wear parts such as the booster pump, power supply, solenoid valve, autoflush and flow valve have a limited service life and must be replaced or cleaned regularly.

Longlife Booster Pump - Service life of up to 10 years with normal household use and compliance with interval use of max. 60 minutes.

• Brushless booster pump - Service life: up to 2000 operating hours when used at intervals of max. 12 hours.
• Standard booster pump - service life: up to 2000 operating hours when used at intervals of max. 30 minutes.
• Ronda Booster Pump - Service life: up to 3000 operating hours when used at intervals of max. 12 hours.
• Passive booster pump - Service life: up to 1000 operating hours when maintaining a maximum water inlet pressure of 3 bar. The pressure can be adjusted using the system's pressure reducer at the water inlet.
• FLOW valve ( flow restrictor ) - If the clean water output decreases, descale the flow valve or replace it. Regular descaling is recommended (e.g., with lemon juice) to ensure proper wastewater flow. A reverse osmosis membrane must produce a certain amount of wastewater to flush the deposited contaminants from the membrane. This is the only way to avoid unnecessary stress on the membrane and thus maintain its long service life.

TDS meter or MicroSiemens meter

Testing your drinking water with a TDS meter is the best and easiest way to determine when a filter change is necessary. TDS meters are also available at our Water Shop24. If the value exceeds 60 ppm, the filters should be replaced. TDS meters, conductivity meters , and pH meters are also available at our Water Shop24.

What does GPD mean?

The designation GPD on the membrane indicates the pure water output per day. GPD stands for gallons per day and is an American unit for liquids. The water output/water quantity of a reverse osmosis membrane is generally specified in GPD. For clarity, this is converted from GPD to liters per day. For every reverse osmosis membrane and every reverse osmosis system, the water output is specified in GPD and liters for the daily output. In addition, a further conversion from GPD to liters per minute is performed. This quickly shows how quickly the osmosis water is produced and gives you a precise idea of ​​how quickly it is produced. This allows you to determine and select the optimal reverse osmosis system based on your water requirements.

How many liters are in 1 gallon?

The conversion from gallon to liter is: 1 gallon = 3.7854100 liters

Determine the performance of a reverse osmosis system

The pure water flow is generally determined without the rinsing phase. You will need a 1-liter measuring cup and a stopwatch for this.

Proceed as follows:

1. Open the osmosis faucet.
2. Typically, an osmosis system begins with an automatic flush (integrated autoflush). This is a flushing phase lasting approximately 18 seconds during which the water flow is reduced.
3. It is essential that you wait until this rinsing phase has completed before you carry out the time measurement for the volume quantity determination.

• The flushing phase is recognizable by the fact that during this time (approximately 18 seconds) only a small amount of water (stale water from the system) flows from the reverse osmosis faucet. The larger amount of water flows away through the drain hose during this time, since the flushing function is activated at the same time.
• The actual osmosis water production can be recognized by the increasing, stronger water jet after these first 18 seconds, and at the same time the pump can be heard more loudly.

1. To ensure the rinsing phase is complete, start the timer when you turn on the faucet. After 18 seconds, stop the timer, let the water continue running, reset your stopwatch, and then start filling the 1-liter measuring cup, simultaneously restarting the stopwatch.
2. When timing, stop the water supply after 30 seconds, as the osmosis system's output is given in liters per minute.
3. Double the amount in the measuring cup and you will get your system's performance value.

Note: The performance and quality of the pure water produced by a reverse osmosis system depends on the water quality of the tap water, such as temperature (at 20°C), conductivity, hardness, and pH. With an average tap water concentration of approximately 250 ppm, pure water with a conductivity of approximately 5-25 ppm (8-40 µS) is possible (without mineralization). The cooler the tap water, the better the pure water quality can be achieved. However, the performance decreases by approximately 4% for every 1°C lower water temperature – and vice versa.
