What Is Reverse Osmosis

Simply put, reverse osmosis is a filtration process used for improving the quality of water.

How does reverse osmosis work?

Reverse Osmosis is a great way to filter your home’s water. Water is forced through a porous membrane and this membrane catches particles such as arsenic (pentavalent), barium, cadmium, cyst, fluoride, chromium (hexavalent/6), chromium (trivalent/3), lead, total dissolved solids (TDS), nitrates and nitrites, radium 226/228 and selenium that would otherwise be ingested and can cause major health problems.

Is it a good idea to drink bottled water instead of tap water?

Because water contamination is a concern, consumers in America and around the world have gone from drinking tap water to drinking bottled water giving them a sense of security for what they are consuming. What is not realized is that tap water in most big cities must be disinfected, filtered to remove pathogens, and tested for cryptosporidium and giardia viruses (Postman). Bottled water does not have to be. And city tap is tested for coliform bacteria 100+ times a month where bottled water is tested once a week (Postman).

What happens to tap water after it has been tested and filtered?

So, tap water is tested, filtered and treated as the city deems necessary to provide clean drinking water, but what about when the water leaves the treatment plant? After the water has been treated it is pumped to your home through miles of piping. In the travel to your home the water is susceptible to contamination. Depending on where you live and how old the piping is, the water can be exposed to a number of different contaminants through different situations. Spokane, Washington, for example, switched from septic systems to city sewer and when doing so left the septic tanks in ground. These septic tanks are vulnerable to leaking and can leak into water pipes that have been buried below the septic system.

Also, old water pipes made of terracotta, wood, cement with asbestos aggregate, lead, iron and galvanized steel piping are part of the network of piping which are vulnerable to corrosion and breakage. This can lead to contamination of the water before it reaches your home. So, though the city has decontaminated the water at its source, the water that reaches your home may not be.

Why invest in a reverse osmosis system?

A reverse osmosis drinking water system “gives the consumer an inexpensive tool to ensure that their drinking water is largely free from health-related contaminants (Battenberg).” To learn more about a reverse osmosis system for your home, please call 509-381-7818 or check out our reverse osmosis system here!
