Reverse Osmosis::Not the Best Home Water Filter?
Here's a little Q&A for my readers starting with; why is reverse osmosis not the best water filter from a conservation standpoint?
If you are a conservationist, your primary goal is to save or conserve the planet's natural resources. Freshwater is one our most important natural resources. No one could survive for long without it.
Freshwater Shortage May Be Coming
Researchers believe that there will be freshwater shortages in many countries, within the next few decades, due to increased population, industrial use, global warming and simple waste.
Home Water Filters Reduce Waste
One of the good reasons to use home filters, rather than buying bottled, is to reduce waste. Wastewater is created when the bottles are made and during other manufacturing processes. According to scientific estimates, for every single bottle that is suitable for drinking, three bottlefuls are wasted.
Reverse osmosis or RO is even worse, in terms of wastewater created. A household system that supplies 5 gallons per day could create 40-90 gallons of wastewater. That creates a burden on the home's septic system, as well as causing problems for the environment.
Why is reverse osmosis not the best water filter for chemical reduction?
The porous membranes of RO systems vary in size, but the smallest membranes will allow chemical contaminants to pass through. There is no way to stop them.The only effective means for chemical reduction is to pass the water over carbon granules or a carbon block. The chemicals are trapped through a process called adsorption.
Some of the latest household RO systems include a carbon stage for chemical reduction. But, the question is this. Why is an RO step necessary? In private homes, it is not.
For large scale treatment facilities and other industrial applications, pressure can be increased in order to reduce wastewater. Although some bottle beverage manufacturers use only an RO step, most use a carbon filter to improve the taste, which also improves the safety.
It is not possible to increase the pressure in a household enough to increase the efficiency of an RO system. It is also impractical to ask a homeowner to check the RO membranes on a daily basis for wear and tear.
So, while RO may be well suited for industrial applications, it is not the best choice for the private homeowner. Here's another question.
Why is reverse osmosis not the best water filter for lead reduction or cyst reduction?
If you have a problem with lead or you are concerned about cysts, RO may have been one of the systems suggested for your home. RO can only reduce the lead content to the federal action level, which means that some of the heavy metal could still be present and no amount of lead exposure is safe.
Better Water Filter Method
A step called ion exchange will remove more than 99.9% of all traces of lead from a sample. For 99.9% cyst reduction, a sub-micron particle filtration step is necessary. Luckily, there are some good home systems that include all of those steps, waste no water, use no electricity, last longer and cost less than RO.
Why is reverse osmosis not the best water filter for your home? Now, you know the answer. Now you know which type of water filter you should have in your home - a multi stage water filter.
