Reverse Osmosis Systems

How it works and how SpringSoft can help you.

1. Pre-Filtration

The Reverse Osmosis membrane is generally combined with sediment pre-filters to remove larger particles before the Reverse Osmosis stage. This protects the Reverse Osmosis membrane, focusing its efforts solely on the smaller particles and contaminants.

2. Reverse Osmosis Membrane

Reverse Osmosis is a relatively straightforward process of filtration. The Reverse Osmosis process involves removing dissolved inorganic solids e.g. sodium,potassium etc from your water by running the water through a semi-permeable membrane . The membrane within the Reverse Osmosis unit is capable of removing particles with a size of .001 micron and above. (Please see some of the major solids the membrane removes listed below)

3. Carbon Finishing Stage

After the Reverse Osmosis stage the water flow is directed through a carbon finishing filter. This final stage affects the taste and colour of the water ensuring your water is perfect for drinking purposes.

So what do you need a reverse osmosis system for?

Reverse Osmosis systems are designed for drinking water only.

This means that you will only use the reverse osmosis unit at your drinking water tap and not for all your incoming water supply. The reason for this is that the unit is capable of treating a specific volume of water at any one time and the the average daily use of a household would be above its capacity.

Many people combine the installation of a Reverse Osmosis unit with a water softener. The reason is that the majority of water softeners remove limescale through an ion exchange process in which a certain amount of sodium is dissolved in the softened water. We should always be mindful of the sodium we introduce into our diets. N.B. High levels of sodium are not advised for small children and those with high blood pressure.

Important Considerations

1. How many stages of pre and post filtration has the Reverse Osmosis unit you are considering? What are those stages? Ask your equipment provider to break it down for you so you know what you are getting

2. A third tap is generally used and needs to be installed on your counter top with a Reverse Osmosis unit unless you have already installed, or purchase, a tri-flow tap. Those with specially designed kitchens often find that though the tap is aesthetic it does not marry well with their existing kitchen. SpringSoft carry a small range of tri-flow taps however if you need something even more specific we can advise you on specialist retailers.
