How Does Reverse Osmosis Work To Make Your Tap Water Safer

How does reverse osmosis work? It is a process by which your tap water passes through a semi-permeable membrane with a very fine pore. As this happens, certain contaminants are rejected such as some as heavy metals, some inorganic chemicals and salts.

Unfortunately some healthy minerals also get rejected so if this is a filtration system you intend on using, it might be a wise idea to ask your physician if it is ok for you to drink water that has the essential minerals taken out.

Reverse osmosis (ro) is limited as to the kinds of drinking water contaminants it will reduce. For example, because many synthetic chemicals, such as herbicides and pesticides are smaller, molecularly, than water, the ro membrane is unable to reject them. Therefore these harmful contaminants are left in your tap water.

Some of those contaminants have been linked to different types of cancers.

On the plus side, ro systems can effectively reduce some contaminants such as arsenic, copper, fluoride nitrate/ nitrite and particulate matter.

After the water has been filtered, it is stored in a holding tank. Unfortunately this process is slow and expensive. Most point-of-use reverse osmosis systems produce less than 1 gallon per hour and wastes around 2-3 gallons of water for every gallon it produces.

If you purchase this system, be prepared to spend around 18-24 cents per gallon of filtered water. This is expensive when compared to cheaper filtration systems that can remove a decent range of contaminants and produce filtered water at around 8 cents per gallon.

After water passes through the ro membrane, the product water passes through a holding tank. The process is slow and wastes 3-4 gallons for every one gallon of drinking water produced.

So to answer the question "how does reverse osmosis work? in a different way - truth is, by itself, ro is not sufficient to produce "healthy" drinking water. It has to be used with an additional filtration technology to truly be effective in removing a wider range of the more common synthetic chemicals.
