The problem with Reverse Osmosis
Depending on the type of reverse osmosis system that is used and the size of the pores in the membrane, anywhere from three to five gallons of water is wasted for every one gallon that is cleaned. Water is too precious a commodity to waste like this.
Once the filtered water is produced it is a highly reactive “sponge” that will absorb contaminants from the air and the container if not handled or contained to standards.
On its own, it lets a lot of bad things through -things like: chlorine, chloramines, hydrolysable phosphates and ortho-phosphates, VOC’s and pesticides, all found in tap water, will all pass through an R/O membrane unless pre-filtered. Micron filters block particles that would pass right through a reverse osmosis system membrane.
If the water that is being filtered is below 75 degrees when using low pressure, 65psi or lower, R/O system, efficiency drops drastically. Reverse osmosis systems are very slow to produce water. Systems generally produce only 1 to 2 gallon of water per hour. A well functioning R/O membrane will not only remove the hardness from your tap water it is also capable of stripping electrons off water molecules making the filtered water acidic, (pH less than 7). Also, drinking de-mineralized water is not healthy. The trace minerals found naturally in ground water are good for your health. Depending on where you live, your water may be your best source of potassium or other minerals.
Studies have shown that drinking de-mineralized water on a regular basis is bad for the digestive system and sometimes results in mineral deficiencies. Installing reverse osmosis systems in the home could cause similar health problems for you and your loved ones.
