What is Reverse Osmosis?

If you are like many you’ve probably asked yourself what is reverse osmosis? Look no further than Reverse Osmosis Reviews. We are considered to be the official review site for all reverse osmosis systems. We will list some of the top reverse osmosis systems available:


So what is Reverse Osmosis?

RO (Reverse Osmosis) is the most effective and convenient method of filtering water. This process happens by squeezing water through small semi-permeable membranes that are rated at 0.0001 micron (equals to 0.00000004 inch). This technology is used to make bottled water (most, but not all). Reverse Osmosis is the only current technology capable of desalinating sea water and creating drinkable water.

There are other non-reverse osmosis filters that are far less effective. The pore size on these filters are much bigger. They generally range from 0.5 – 10 micron. These non-RO machines can filter out larger, coarse particles, sediments and elements. But this is only done up to their micron rating. Any sediment or element finer or smaller, along with most dissolved substances cannot be filtered out. The end result is water that is far less clean and safe compared to reverse osmosis filtration systems.


What is Reverse Osmosis?

Reverse Osmosis is known as Ultra-Filtration by industry standards. This Ultra Filtration represents the state of the art technology revered by the industry. Reverse Osmosis was developed around the late 1950′s with U.S. Government funding. Initially the idea was create to find solutions to desalinating sea water . Today reverse osmosis is considered the most efficient and effective way of filtering water and has become the mainstream technology in doing so. Reverse Osmosis is used by the majority of bottled water plants, and by others in the industry that require ultra-refined water through the manufacturing process. This advanced technology is now available for both homes and offices for drinking water.

How the Reverse Osmosis Process Works?

This is a process in which water molecules are pushed through a 0.0001 micron semi-permeable membrane by extensive water pressure. The long sheets of membrane are sandwiched together, at which point they are rolled up around a hollow central tube in a spiral like fashion. The rolling up configuration is generally referred to as a spiral wound membrane or a module. These membranes are available in many different sizes for processing different amounts and quantities of water. Typically, most modules for home treatment can be as small as 2 inches in diameter and 10 inches long. Membranes used for larger industrial purposes may be 4 inches in diameter and up to 40 inches long.

For a membrane to be usable it must be in some type of housing or container, so that the pressure is able to be maintained on the surface. It is this extensive pressure that allows the energy to force the water through the membrane, thus separating it from other unwanted substances. The most amazing fact about Reverse Osmosis is that the substances that are left behind are automatically diverted to a waste drain. Thus enabling the system to continue the process without build up, which generally happens with other conventional filtering devices. This is action happens by using a small portion of the unprocessed water to move away any rejected substances to filtration drain. This is the main reason why Reverse Osmosis Systems can last so long with very little maintenance of the membranes.
