Is Reverse Osmosis a Better Home Water Filter Than a Traditional Filter?
What are your thoughts on the use of reversible osmosis technology? Most likely not much, at least not until you’re approached about purchasing a reverse osmosis water filter for home. If we may interfere with a polite warning that adopting all of that hullabaloo as indisputable reality might not be in your best interests, we would like to do so.
It’s important to note that reverse osmosis is one of the solutions for cleaning water for drinking and personal use available among the many different technologies available today. In this situation, the contaminants are retained on one side of the membrane while the pure solvent, in this case, water, is allowed to pass through.
As a matter of fact, while reverse osmosis may be appropriate for some industrial activities that require demineralized water, it is far from ideal for home water filtration applications.
However, while there is debate over the healthfulness of demineralized water in comparison to naturally balanced drinking water that contains healthy minerals, it appears safe to suggest that naturally balanced drinking water contains all of the necessary nutrients for human well-being and is, therefore, more nutritious.
Depending on the molecular size of the pollutants, reverse osmosis membranes have large enough pores to allow them to be removed from the water. When it comes to man-made substances such as herbicides and insecticides, reverse osmosis is unable to remove them since their molecular size is smaller than that of water.
Therefore, every reverse osmosis system must be followed by a charcoal filter and, if possible, a UV light to disinfect (kill) any bacteria that may have managed to get past the membrane barrier during the water treatment process.
In order to dispose of the contaminated water fraction (which is twice to three times the amount of filtered water collected), a large financial investment must be made. Given the current and future global concerns about freshwater scarcity, this might swiftly become an unacceptable waste of time and resources.
A difference between returning a part of rejected water from an onshore desalination plant to the sea and flushing all of the leftover water you paid for but is unfit for drinking down the sink is that one is environmentally friendly (unless you collect it separately for toilet flushing, car-washing and, within limits, for gardening). Keep in mind that, because of the slowness of the procedure, you will require a tank to keep the filtered product until it is time to use it.
Moreover, due to the high cost of energy required to pressurize the contaminated water, as well as the associated maintenance and replacement costs, estimates of the cost of such processing per unit volume of treated water are more than twice as expensive as estimates of alternative filtration systems.
In conclusion, it is recommended to be skeptical of superlative plaudits for reverse osmosis water filters for household use and instead look into more suited alternatives.
The results of his research on the quality of drinking water and the use of household water filters and purifiers led him to build a website where he shares his findings for anybody to consider and draw their own conclusions.
