Reverse Osmosis

Step 1: Pre-filtration

The first step in purifying water with reverse osmosis is meant to protect the membrane. It removes larger sediment, including some dissolved solids, and helps reduce chlorine.

This first cartridge is referred to as the sediment filter or carbon block filter. It helps conserve the membrane, which can get clogged by excess sediment or damaged by exposure to too much chlorine, which you’ll find in municipal water.

Step 2: The Reverse Osmosis Membrane

Following the initial filtration comes the real magic of an R.O. system.

Your water is forced through the semi-permeable membrane under pressure. The membrane is a synthetic plastic material that allows the passage of water molecules. However, sodium, chlorine, and calcium as well as larger molecules like glucose, urea, bacteria and viruses cannot pass.

Steps 3 & 4: Post Filtration and Final Polish

Before your home’s water is ready to drink, it goes through a second carbon filter (or post filter), which removes any remaining contaminants in the unlikely case they slipped past the membrane.

Then the water fills up a storage tank where it waits until you’re ready to use it.

Finally, there’s the in-line activated carbon filter, which gives your water one last polish as it comes out your faucet. This is used to remove any remaining odors or flavors that may come from the system hoses or the holding tank.

A reverse osmosis system can remove that sodium along with other contaminants and dissolved solids, which makes a water softener and an R.O. system an ideal combination for most homes.

When you install a reverse osmosis system, you’ll enjoy better-tasting coffee and tea, clearer ice cubes, and pure, healthy water right from your kitchen sink. If you’re still using bottled water for drinking, you’ll be making a smart investment that saves you money in the long run and is better for the environment.
