RO Membranes for Residential Purpose

Reverse osmosis systems residential water purifiers claim to filter water to remove all harmful microorganisms. But do they really work and are there any disadvantages to residential reverse osmosis systems? Let’s take a closer look at what reverse osmosis is and whether these filter systems are the best ones to use in your house.

Reverse osmosis works by letting unfiltered water pass through a semi-permeable membrane (filter). This membrane is meant to filter our all undesirable substances like chemicals, bacteria, parasites and other tiny microorganisms. While it can work well in an industrial situation, unfortunately reverse osmosis is not the best choice for filtering drinking water.

Concern about wasting water

Up to 8 gallons or more of water can be wasted per gallon of filtered water with reverse osmosis filter systems in the home. This is an incredible waste of water. That means for every 8 gallons of water that passes through the system, only one gallon makes it into your drinking glass.

Slow daily production

You only get a maximum of 15 gallons of water per day from a home system of this type. Compared with other systems such as ion exchange filters, this is a small amount of water and is due to the fact that reverse osmosis relies on standard osmotic pressure (the pressure exerted by the flow of water through a semi-permeable membrane). This restriction means that there is no way to get more than 15 gallons of water per day from the filter. This may be OK for some, but big families or people who drink a lot of water will be left frustrated.

Water produced is expensive

Besides the costs of wasted water, there are more hidden expenses. While the filters themselves are not overly expensive, you will need to replace membranes every two or three years. Kindly visit ro membranes to find more information.

Challenges of Installation

Many reverse osmosis systems have designs which will see you under the sink for several hours installing the filter. Unfortunately it usually requires a plumber which can add significantly to the cost of the filter.

Reverse osmosis systems residential water purifiers are not the best choice for your home filter system. Consider instead an ion exchange filter in combination with carbon filtration and sub micron filters. This type of system will provide better filtration, more water, less waste and less maintenance costs. Take action now, do your research, and find a system that will best meet your needs!
