More Tips For Doing a Reverse Osmosis Water Treatment Comparison


Visitors: 146

I don't know a thing about you, but I'll bet that searching for the right home water filtration system is as frustrating as it is confusing. It's hard to know what systems are truly effective and worthwhile when all we see are reviews that are always on one end of the extreme or the other. For that reason, it is important to do a reverse osmosis water treatment comparison with carbon block filters. These two types of home water treatment systems are the most popular out there and in order to really figure out which is best, you have to do a detailed comparison.

When reading reverse osmosis reviews, what stands out the most? First off, water is purified in a reverse osmosis system by pouring water under pressure through a porous membrane. The molecules of most organic contaminants common in tap water are larger than water molecules thus the membrane rejects them along with the minerals and most of the water. On one hand, that is great because you get water that is free of organic contaminants. Unfortunately there is always a downside and in this case, the membrane takes the good stuff out along with the bad. The minerals in water are essential to good health. Did you know that the places on earth where people live the longest and have disease-free lives are near bodies of water with high mineral content?

It doesn't stop there. When doing a reverse osmosis water treatment comparison, you also have to take into consideration how effective the method actually is. So as we discussed, many organic contaminants are rejected by the membrane used in reverse osmosis, which is fantastic. However, reverse osmosis does not remove synthetic chemicals that are molecularly smaller than water. That's a shame since virtually all synthetic chemicals have smaller molecules than water. Examples of these synthetic chemicals include pesticides and herbicides. In order to be truly effective, reverse osmosis systems have to be used in combination with a carbon filter.

Reading reverse osmosis reviews as well as reviews of other kinds of water filtration systems is a good place to start when you are trying to weigh which system is best. Along with effectiveness, you also have to consider the costs. Replacement parts are a big expenditure when you use a reverse osmosis system. While the makers of these systems stretch the truth a little bit and claim that the membranes and other parts last for years, past consumers have said otherwise. Look into the prices of replacing these parts before diving into a decision.

Finding out the approximate price per gallon is also an important step. When doing a reverse osmosis water treatment comparison with the carbon block filtration system, it is easy to see that the latter is substantially cheaper. Reverse osmosis systems cost 18 to 24 cents per gallon while carbon block filtration systems cost a little less than 10 cents per gallon.

Another important factor to consider when doing a reverse osmosis water treatment comparison with other filtration systems is whether any water is wasted in the process. Unfortunately, with reverse osmosis, for every gallon of water produced around 2 to 3 gallons of wastewater are produced. It is the most wasteful of all the different water purification methods. In this day and age when everyone is going green, it is not such a good option. Reverse osmosis is also a slow process, producing less than a gallon of water per hour.

So there you have it. We are all aware that at this point, any water filter is better than not having one at all. In order to get the most for your money however, it is absolutely necessary to educate yourself about your options by reading reverse osmosis reviews as well as reviews of other filtration systems. After some research, I think it's safe to say that the negatives outweigh the positives with reverse osmosis systems. Writing out a simple pros and cons list will help you clarify what's best. In terms of providing the most effective, inexpensive, and environmentally friendly system, carbon block filters currently top the list.
