What is Reverse Osmosis and How Does it Work?

Reverse osmosis is a water purification process that uses a membrane to remove impurities from water. The membrane allows water molecules to pass through but blocks larger molecules and contaminants like salt, minerals, bacteria, and viruses.

To understand the process, imagine a filter that has very tiny holes. When water is pushed through the filter with pressure, only the tiny water molecules can pass through the holes, leaving behind the larger impurities.

A reverse osmosis system consists of several components that work together to purify water. First, a pre-filter removes larger particles like sand and sediment to prevent them from clogging the membrane. Then, a pump applies pressure to the water and pushes it through the semi-permeable membrane, where impurities are trapped and removed. The purified water is then stored in a tank until it's needed. Finally, a post-filter removes any remaining impurities and ensures the water is clean and safe to drink.

The benefits of reverse osmosis include improved taste and safety of drinking water. Reverse osmosis removes contaminants like chlorine, lead, and arsenic that can affect the taste of water. Additionally, it removes harmful contaminants like bacteria and viruses, making water safer for consumption.
