![]() Reverse osmosis is a common type of water filtration, so what exactly are clean water filters and how are they different? One thing you might have noticed at this point is that reverse osmosis seems to filter contaminants from water. There are various types of water filters but all are devices that contain one or more filtration media to reduce the number of contaminants in water. On the other side of the membrane is the solution with a low number of solutes, or rather water with substantially fewer contaminants. You force that water through a semi-permeable membrane that allows the solvent (water) to pass through the membrane but not the other contaminants or solutes that are in the original solution. With an RO water system, you start with water that contains a higher number of contaminants. Reverse osmosis is used primarily to reduce the number of contaminants in water, so let’s put the reverse osmosis process in real terms. In reverse osmosis, an external force greater than the osmotic pressure is required to force a solvent across a membrane. In a reverse osmosis filtered water system, you have a solution with a high concentration of solutes forced across a semi-permeable membrane to a solution with a low concentration of solutes. Reverse osmosis turns this process completely around. Osmosis continues until the solutions on both sides of the membrane reach a state of equilibrium. Solutes are any dissolved substances in the solution on either side of the membrane. ![]() The membrane must be semi-permeable, meaning it allows some molecules to pass but not others. The solvent or fluid that passes through a membrane in osmosis is usually water. Osmosis is the movement of a solvent through a membrane from a solution with a low concentration of solute to a solution with a high concentration of solute. Osmosis is a natural process that is critical for our lives and the lives of all living creatures around us. ![]() To fully understand the reverse osmosis process, it is helpful to start with osmosis. We will now discuss how reverse osmosis works and what it is. Reverse osmosis (RO) systems use reverse osmosis to dramatically reduce the number of contaminants in water. Here’s how a water filter differs from a reverse osmosis water system. However, you may find that you want the benefits of both systems for your home water filtration in which case, you may choose to invest in a system that combines both filtration methods. Both reverse osmosis and water filters have advantages that make them ideal for certain applications. Are you curious about the differences between how water filters and reverse osmosis systems function? While both types of systems are used to reduce the number of contaminants in a sample of water, they function in quite different ways.īy understanding the differences between a water filter vs RO water filter system, you’ll be better informed and positioned to find the water filtration system that is right for your needs. ![]()
