How Does Reverse Osmosis Work?

There are several ways to treat water. One of the most common types of filters on the market is the carbon filter, which uses a porous piece of carbon to trap particles that make your water impure. While carbon filters can clean a lot of particles out of water, if the particles are small enough to fit through the holes in the filter, the filter obviously cannot remove them. Unfortunately, the smaller the holes in the filter are, the harder it is to push water through them. This is where reverse osmosis comes in. 

What Is Osmosis?

Osmosis is a naturally occurring process. For example, the walls of the cells in your body are what are called semi-permeable membranes. They will allow some particles to pas through them but keep other particles out. Normally, particles will pass from an area of high pressure to an area of low pressure until the pressure on both sides of the membrane is neutral.

What Is Reverse Osmosis?

With reverse osmosis, the operator uses high pressure to force water through a membrane that it would otherwise not pass through. The holes in the filter can be so small that they only allow a water particle to pass through. Thus, anything that is bigger than the water molecule will stay on one side. A reverse osmosis filter will remove most chemicals and organisms, but you may want a back up source of filtration just in case. 

UV Radiation or Distillation

A secondary filter can help to eliminate any chemicals small enough to pass through the osmosis screen. Such a filter could use UV radiation to kill any germs and bacteria found in the water. Another option is to distill the water, which involves boiling the water, trapping the water vapor, and allowing it to condense back to a liquid. Using multiple filtering techniques is the best way to make sure that your water is as pure as possible. 

If you are looking for a water filtration service for your house or business, do not look for just one filter. Remember that the more filters you have in place, the more sure you can be about your water source. In many cases, you can install filters along the water line into your house. Thus, your filter will only filter water when there is a demand for it. You will have to make the choice for yourself if you want to filter all of the water going into your house or just your drinking water. Contact a company such as Water Tec for more information.
