Nano-filtration for Water Tank Explained
How does Nano-filtration work as opposed to Reverse Osmosis?
Reverse Osmosis (RO) and Nanofiltration (Nano) are very similar, although Nanofiltration is the slightly newer technology for water tank cleaning. In appearance, they are virtually identical and both use essentially the same technology to remove impurities from water or other liquids
In both systems, Membrane Elements (or membranes, or elements) are used to separate a liquid from contaminates. Membranes are basically filters with very small “openings” that prevent contaminates from passing through when the liquid that is being purified is “pushed” through the membrane.
Nano was developed primarily for drinking water applications because RO was found to remove some of the minerals in water that are considered beneficial for human consumption.
Nano allows these minerals to pass through the membrane with the water, but the Nano membrane will “block” pesticides and other contaminates that can be harmful to people.
Reverse Osmosis has been the traditional method for emergency water filtration due to the ability to desalinate water.
However the downside to reverse osmosis as a method of purifying drinking water is the removal of healthy, naturally occurring minerals in water.
The membrane of a reverse osmosis system is impermeable to natural trace minerals. These minerals not only provide a good taste to water, but they also serve a vital function in the body’s system.
Water, when stripped of these trace minerals, can actually be unhealthy for the body. Reverse osmosis also wastes a large portion of the water that runs through its system.
It generally wastes two to three gallons of water for every gallon of purified water it produces. Reverse osmosis is also an incredibly slow process when compared to other water treatment alternatives and requires significant maintenance.
These problems are not encountered with a nanofiltration system and hence this is why Safe H2O uses Nanofiltration to treat water. This is why Safe H2O is the cost effective way to clean your water tank.
The following chart demonstrates the effectiveness of Reverse Osmosis (RO) relative to Nanofiltration (Nano) and other common filtration technologies.
