Answers to Your Questions on Reverse-Osmosis Filtration

Posted on: 23 August 2016

Reverse-osmosis systems purify the water in your home by forcing the water through a semi-permeable membrane that removes even the smallest of impurities. This results in pure, great-tasting water. Most systems are for the whole house, although there are reverse-osmosis systems designed for use on single taps. If you are considering water purification, the following guide can help you better understand how this system works.

Are there multiple filters in a reverse-osmosis system?

Most modern systems use sediment filter to remove small particles, a carbon filter to remove organic particles, and finally the reverse-osmosis filter to remove dissolved solids like lead. When there are three filters, with water passing through the tight reverse-osmosis filter last, your reverse-osmosis filter is less likely to get clogged, and it will last longer.

Can reverse-osmosis systems remove chlorine from water?

If you are concerned about chlorine, either for your own health or for that of your pets, rest assured that the combination of the carbon filter and the tight reverse-osmosis filter removes nearly all chlorine and chloramines from the water. This will render it safe for use in fish tanks, where chlorinated water can be a concern.

Are reverse-osmosis systems water efficient?

The short answer is no, not all systems are efficient. Due to the filtration system, some water will be sent down the drains instead of to the tap. Fortunately, you can get systems with water-catchment options that recirculate the water through the system instead of allowing it to go to waste. There are also systems that reroute the excess water to a holding tank that is hooked to faucets that don't require purified water, such as outdoor irrigation spigots.

Can you use reverse osmosis in tandem with a water softener?

This is common practice in areas with very hard water. Most water softeners are designed to remove calcium and lime, which can quickly clog the finer filters found in a reverse-osmosis system. By combining the two, you will have soft water that is also very pure, which makes it very suitable for drinking.

What are the basic maintenance needs of these systems?

General system cleaning and filter changes are the main needs of the system. During a general cleaning, the system is taken apart and flushed by your treatment professional. They will also check the condition of the filters at this time and change them as needed. How often filters require changing depends on your water impurities and use patterns. Generally, most of the filters in the system can last a few years, although the carbon filter may require more frequent changing.
