What Does a Reverse Osmosis Filter Actually Do?

water-treatment-system-under-sinkWater treatment system installation and service is an important job that more and more plumbers are providing for their customers. Homeowners are more concerned than ever about pollutants that may be in their fresh drinking water, and thankfully there are numerous methods available to filter and purify the water coming into a home through the municipal water lines.

The difficult part of water treatment for a home is finding the right treatment system. One popular type is the reverse osmosis filter. It’s not ideal for all circumstances, but a professionally installed RO filter can remove many types of minute impurities: lead, fluoride, nitrates, sulfates, chlorine, chloramine, and pesticides. RO filters are also useful to pair with water softeners to prevent too much sodium from entering the water.

So How Does a RO Filter Do All This?

The name reverse osmosis makes an RO filter sound a bit mysterious. What’s it actually doing to make it so powerful at removing such tiny impurities?

The secret is in the word osmosis, which means the movement of molecules through a permeable membrane from an area of high concentration to an area of low concentration in order to stabilize the two areas. This natural property can be made to work to force water through a powerful membrane that removes many impurities.

A reverse osmosis filter is fit onto a cold water line. The freshwater enters it and is placed under high pressure after first passing through a larger filter that removes sediment and silt. The high pressure forces the water to move through the semi-permeable membrane that only allows particles .001 microns or smaller to pass through. This is where most of the contaminants in the water are trapped. The water continues to the lower pressure side, after which it passes through a charcoal filter to help improve taste. From there, the water either goes directly to a faucet or into a holding tank to make sure purified water is immediately available. The impurities are removed from the RO filter through a drain line.

Reverse Osmosis Filter Installation

An RO filter isn’t something a homeowner can purchase and attempt to install on their own. Most RO filters are “point-of-use,” which means they’re attached to a specific faucet in a home. There are whole-house options as well, called “point-of-entry” filters, which are usually installed in the garage of a home. But no matter the type of RO filter, if it’s poorly matched to a home or poorly installed, it can create problems such as low water pressure or a filter that is quickly ruined. If you’re looking for the best in water treatment, make sure you rely on a licensed professional plumber.
