What is RO Membrane? Know its role in water purification

Today, having clean drinking water is more important than ever. Water from taps or other sources may look clear, but it can still contain unwanted substances that are not safe for daily use. This is why many people now choose water purifiers for their homes.

RO water purifiers have become very common because they help make water cleaner and safer to drink. Many families use them to feel more confident about the water they give to their children and elders every day.

If you are using a water purifier or planning to buy one, you might have heard the term RO membrane many times. In this blog, we will explain what exactly an RO membrane, how it works, and why is it considered most important part of an RO system.

What is RO membrane?

An RO membrane is the main part of an RO water purifier that helps make water clean and safe to drink. It is a thin layer inside the purifier that is very fine screen to strain out the unwanted particles so that you only get clean water.

Unlike normal filters that only remove visible dirt or bad smell, an RO membrane cleans water at a much deeper level. It removes things that you cannot see, like extra salt, harmful metals, and other unwanted substances mixed in the water. This process removes up to 95-99% of dissolved impurities, which is why RO membranes are used when water needs proper and thorough cleaning.

How does an RO membrane work?

Water from your tap or supply is pushed through the RO membrane under pressure. The membrane has extremely tiny holes, so small that only water molecules can pass through RO membrane. This membrane works like a very fine cloth that only lets clean water go through. 

As water moves ahead, all the unwanted things stay behind and are flushed out. Only clean and safe water continues and gets stored for use. This process happens automatically every time you turn on your purifier. 

Why is the RO membrane important?

• Removes extra salts: In many homes, water has too much salt mixed in it. This spoil the taste and may not be good for health. The RO membrane removes this extra salt and makes the water lighter and better to drink.
• Reduces harmful metals: Sometimes water picks up harmful metals from old pipes or underground sources. Metals like lead or arsenic are not safe for the body. The RO membrane helps reduce these harmful metals so the water becomes safer for daily use.
• Blocks germs and chemicals: An RO membrane may not stop every single germ, but it removes most bacteria and viruses. When it works along with other cleaning methods in modern RO purifiers like UV or UF, the water becomes much safer to drink.

Why should home users care about the RO membrane?

If you use an RO water purifier at home, the RO membrane plays the biggest role in keeping your water safe. It quietly does the main job of cleaning the water before you drink it. Here is why it matters to you:

• Health and safety: Drinking clean water is important for staying healthy. The RO membrane helps remove unwanted substances so the water you drink is safer for you and your loved ones. 
• Better taste: With extra salt and impurities water can taste bad. But when extra salts and metals are removed, the water tastes lighter and more pleasant to drink every day.
• Peace of mind: When a good water purifier with RO membrane is installed, you can feel relaxed knowing the water in your glass is clean and safe.
