A Simple yet Effective Water Purification System

For many people, the functioning of a reverse osmosis system seems mysterious. The truth is: it’s a relatively simple yet effective way to purify water. The system starts with a cold water line valve. This is where the water that is to be purified enters into the device.

Next, it passes through a pre-filter. The purpose of the pre-filter is to remove things like sediment, dirt and silt. At times, the pre-filter will include carbon to remove chlorine. From there the water is passed through the reverse osmosis membrane. This membrane is the centerpiece of the entire system. It is here that the vast majority of the contaminants are removed from the water.

The water then travels to a post filter. This filter is usually made of carbon, and its purpose is to remove residual odors and taste from the water. Most reverse osmosis filters come equipped with an automatic shut off valve designed to conserve water, a check valve designed to prevent backflow that could damage the reverse osmosis membrane, a flow restrictor that controls the rate water flowing through the membrane to ensure maximum purification, and a storage tank that keeps the purified water pressurized until it is delivered to the faucet.

The final part of the reverse osmosis system is the drain line. This is where impurities and other contaminants are drained from the unit. Ultimately, reverse osmosis is a simple and effective way to purify water.
