Like most things, there are both advantages and disadvantages to reverse osmosis filtering systems. These systems do a decent job of filtering a wide range of substances, but they also leave many behind. Read on to learn what people can realistically expect from this type of water processing system:
Reverse Osmosis Advantages
Reverse osmosis is a system of water filtering that involves the use of a semi-permeable membrane. When water is sent through this membrane, the majority of the contaminants present in it won't flow through. These membranes are capable of filtering not only a wide range of particles but also bacteria, other disease-causing pathogens, and organic compounds. Reverse osmosis systems are generally capable of filtering over 90 percent of water contaminants.
This filtering method is also effective for providing mineral-free water for processes that require it. For example, water processed this way may be used in print shops. This method of water treatment may also be particularly helpful in places that do not have access to water treated through a modern municipal system. In such places, it may be the method of choice for ensuring that water is pathogen free.
Reverse Osmosis Disadvantages
One of the main disadvantages of this type of water filtering is its lack of effectiveness when it comes to very small substances. For example, it is known to be very effective at filtering larger structures, such as salts and minerals. However, some molecules are so small that they can pass through the small pores used in this type of water processing. As such, this type of processing may leave water virtually free of bacteria but allow a range of chemicals, including pesticides and herbicides, in.
Another problem with this type of water processing is the amount of waste it causes. For each gallon of water that is filtered using this method, another couple of gallons is typically wasted. When it comes to speed, it doesn't measure up either. It's much slower than other filtering methods.
Due to the fact that these water systems allow some harmful substances to remain in drinking water, they are usually used along with a carbon filter that serves to help catch the undesirables that make it through. Some people prefer to select sub-micron carbon-based water purification systems from the outset, however. These systems are capable of filtering the dangerous substances reverse osmosis systems can't touch. They also tend to be less costly and less wasteful.
