The vast majority of reverse osmosis reviews are positive, and in some cases there are glowing comments about the ability of RO units to clean up brackish well water, or water with very high iron or sulfate content. And I would also praise RO systems' ability to clean up such water. But most of us don't have brackish water that needs this very expensive and cumbersome technology. In this article let's take a look at a reverse osmosis water treatment comparison with a newer water filter technology option.
Bad tasting and/or bad smelling water is common in a lot of the US. Sometimes the brackish water, or the water with high mineral content, is just undrinkable. That same water can be cleaned up with a RO system to be very drinkable, but I have always found such water to be very stale or flat tasting.
A flat or stale taste with filtered water can be tolerated, but it does indicate another issue. You see, the funny taste comes from the lack of minerals in the newly filtered water. RO systems do a very good job of removing minerals...too many minerals, perhaps. We need minerals like potassium and calcium for good health and water needs minerals to remain neutral. Water without minerals is a bit acidic and it will attempt to regain neutrality by swiping calcium from our cells, teeth and bones. Osteoporosis suffers may want to consider mineral supplements or food additives if they are drinking water from an RO system.
Many experts in the areas of health and nutrition feel water stripped of minerals is unhealthy if used on a long-term basis, since cancer seems to only exist in environments which are acidic.
The RO filter consists of a semi-permeable membrane that filters out any matter larger than a water molecule. This is done by forcing the water through the membrane and sometimes, if there is not adequate water pressure, a booster pump may be needed.
The pores of the membranes are so small that even with sufficient pressure much of the water cannot be forced thru the RO membrane and is simply flushed. This adds to the operating costs.
Since about 1900, chlorine has been the poison of choice to clean up the bacteria in our water systems and you do not want to drink it, or its byproducts. However, RO systems will not remove chlorine, or any other of the synthetic organic chemicals (SOCs) we have in our water, as their molecules are too small and will go right through the membrane. The RO systems must be used together with an activated charcoal filter.
Water passing through a filter of any sort will somewhat reduce the water pressure and this is certainly true of the RO systems. They are very slow and, if you want filtered water for say, bathing, you will need a storage tank capable of maintaining water pressure.
The 'Rube Goldberg' combination of filters, pressurized storage tank, booster pump (maybe), and so forth, leave a lot of things to fail in these systems, and, indeed, it leads to the areas of highest complaints in reverse osmosis reviews... maintenance issues, operation costs and start-up costs.
Ninety-five percent of households in the US get their drinking water from some sort of chlorinated source such as a well or a utility company. If that's the case with you as well, you might want to compare a selective filtration system (also called multi-stage) against the RO system.
In multi-stage filtration the water flows through activated carbon that has been blended with a filter resin and compressed into a solid block. This modern technology filters out the chemicals with the carbon, the minerals leave through ion-exchange, and the rest of the bad guys get trapped with the tiny submicron filter pores. All you get is clean, healthy water with all the healthy minerals still there (by choice).
And, it's all done with no pumps, no storage tanks, no extra maintenance or operating costs, and no need for mineral supplements. - 16477
