Learn about Reverse Osmosis (RO) technology in water filtration systems

RO filtration technology is now considered by experts as an advanced water filtration technology that is widely used in household water filters today. Let's explore the Reverse Osmosis (RO) technology with Karofi in the following article.

1. What is Reverse Osmosis technology?

Reverse Osmosis (RO) is a technology used to remove most of the pollutants from water by pushing water through a semipermeable membrane using pressure.

The RO membrane is a semi-permeable membrane with hole size of only 0.1 to 0.5 nanometers that allows water molecules to pass through, but not dissolved salts, organic matter, bacterias, and pyrogens. It works by 'pushing' the water through the reverse osmosis membrane by creating a pressure higher than the natural osmotic pressure to remove salts (de-mineralization or deionization) and only allow pure water to pass through while keeping most of the pollutants inside the RO membrane.

2. What is the principle of Reverse Osmosis technology?

Natural osmosis is a process that occurs when two solutions are separated by a semipermeable membrane, water from the solution with a higher concentration will move to the solution with a lower concentration to balance the solvent's solubility ratio. Reverse osmosis is the opposite process of natural osmosis, occurring under the influence of external forces. In the process of reverse osmosis, water will move from the solution with a low concentration to the solution with a higher concentration.

3. How does RO technology work?

Reverse Osmosis (RO) technology uses water pressure by a booster pump to force water molecules in the source water to pass through a very fine semi-permeable membrane, which will retain impurities, harmful substances, bacteria, and discharge them. Water after passing through the reverse osmosis process will remove salts and most other inorganic substances, making RO filtration technology very commonly used to convert low-quality water, hard water, or natural water containing many difficult-to-remove dissolved minerals into pure drinking water.

4. Benefits of RO technology

4.1 Removal of impurities

Reverse osmosis (RO) is primarily used to remove impurities from water. This means that all harmful chemicals such as lead and arsenic are removed from the water. Even some parasites are filtered out of the water, protecting you from potential health hazards. If your water source contains a lot of harmful substances, then the RO system may be suitable for you.

4.2 Low energy consumption

The energy consumption of RO systems is relatively low, a standard water purifier consumes between 25 to 60 watts per hour. This makes the water filtration system ideal for those who need to use as little energy as possible.

4.3 Space-saving

RO water purifiers are extremely compact, saving space in your home wherever you want to place them.

4.4 Low maintenance cost

Depending on the quality of input water, Water purifiers often require an RO membrane  maintenance and replacement every 2-3 years while the requirement of other water filter cartridges is at least once every 12 months or longer. Moreover, RO systems are relatively simple to maintain and do not cost to ask for technicians.

4.5 Improved taste of food

When it comes to cooking, many people have found that using RO water has a positive impact on the taste of food. And when RO water is used to prepare hot beverages or soup, the water is clean, safe, and free of impurities. That's why many restaurants use RO water for cooking water.

These are the main benefits of having an RO water purifier. You can save costs, space, and time. Not only that, but the water will also taste better and be better for the health of your entire family.
