What is the role of an RO membrane in Water Purification?
Read here how an RO membrane effectively removes excess TDS, Heavy Metals, and Chemicals to give safe and purified water.
There are many water purifiers out in the market for people to choose from. Important is to first understand the type of water that is supplied to your home. Hard water or water with high TDS is much more difficult to purify than soft water as it has many dissolved solids, chemicals, and other contaminants. To treat such water, you need an RO (Reverse Osmosis) purification technology.
An RO water purifier has various filters that eliminate different types of impurities found in tap water through multiple stages of filtration. The most important of these filters is the RO membrane. This membrane is a thin, semi-permeable layer that has minute pores on it to allow only pure water to pass through it. The impure water on the other hand is released out of the water purifier as reject water.
The input water is pushed through the RO membrane with a very high pressure. This high pressure ensures that only purified water passes through the membrane. Thus, leaving behind various impurities, salts, heavy metals, chemicals, pesticides, and microbial contaminants on its surface.
A RO membrane plays an important role in the water purification. Let's read about these in detail:
- Sweetens the taste of water by removing excess TDS
Total dissolved solids (TDS) include a concentrated level of particles such as inorganic salts and compounds in the water. The presence of TDS in water alters its taste and makes it saltier. An RO water purifier brings down the TDS in water by 90%, improving the taste of water and making it sweeter.
- Removes harmful chemicals and disease-causing impurities
Harmful contaminants such as bacteria, viruses, chemicals, and heavy metals may be naturally present in the water and drastically affect one’s health. These impurities can lead to various water-borne diseases such as diarrhea, typhoid, cholera, etc. Hence, to avoid such illnesses, one must make sure that the water consumed is 100% safe and purified.
- Suitable to purify water from all sources
RO is one of the most sophisticated water purification technologies. Whether your source of water is Ground Water/Borewell, Tank, or Municipal, a Pureit RO water purifier guarantees 100% safe and pure drinking water. While a UV or MF water purifier is recommended when the source of water is comparatively clean i.e. municipal or has less TDS, a Pureit RO water purifier is effective in treating water from all kinds of sources.
Today, the modern RO water purifiers come with many more features. For instance, Pureit has introduced Pureit Copper+ Mineral RO+UV+MF that includes 7 stages RO+UV+MF purification process with a unique Copper Charge Technology™ that charges RO purified with the goodness of copper. The new range of RO water purifiers also come with the benefit of Mineral Enrichment. This ensures essential minerals like Calcium and Magnesium are added back to RO purified water.

FAQs
1) What is the function of a membrane in the RO system?
Reverse osmosis (RO) has nanofiltration (NF) membranes that are commonly used as filtration technology to remove numerous types of dissolved solids from solutions by applying pressure to the solution when it is on one side of a selective membrane.
2) What is a membrane in a water purifier?
Only pure water can flow through the membrane in a water purifier. It is a thin, semi-permeable layer with minute pores. The polluted water, on the other hand, is discharged as reject water from the water purifier. Only pure water flows through the membrane due to the high pressure.
3) How important is the membrane in reverse osmosis?
Membranes have aided in the cost-effective method of water purification. Total dissolved solids, heavy metals, organic pollutants, viruses, bacteria, and other dissolved contaminants have all been proven to be greatly reduced by reverse osmosis (RO) membranes.
4) What is reverse osmosis used for?
Reverse osmosis is a technique that uses pressure to drive water through specialized membranes to remove foreign pollutants, solid particles, big molecules, and minerals. The technology increases the quality of water for drinking, cooking, and other uses.
5) How often should membrane be replaced in a RO filter?
Reverse Osmosis Membrane must be replaced every 6 to 12 months. Carbon Post Filter which can be found in a RO purifier must be replaced every 12 months to guarantee that the water is of high quality.
