What Is Reverse Osmosis Water Filtration and How Does It Work?

According to the UN, 783 million people around the world don’t have access to clean drinking water. Plus, the EPA says that 63 million people in the United States were exposed to unsafe water in the last decade.

To avoid this, you should consider reverse osmosis water filtration. Read below to learn how it works and why it’s good for you.

What Is It?

Reverse osmosis is a method of filtration that removes molecules and ions from a solution by applying pressure to it. The pressure is applied to a selective membrane that’s semipermeable.

Water can cross a membrane and large molecules can’t. What happens is the solute or large molecules get more concentrated on one side of the membrane while the other side becomes more diluted.

How Does It Work?

When you combine regular osmosis and transported mass by way of diffusion, you get reverse osmosis. The movement of molecules from a region with higher concentration to lower concentration makes for diffusion.

As mentioned above, the semipermeable membrane lets the water pass while blocking the larger molecules. Osmosis and diffusion continue until they reach an equilibrium.

Osmosis can be stopped, slowed, and reversed when the correct amount of pressure gets applied to the membrane on the concentrated side.

When water gets moved across the membrane and against the concentration gradient, and from a lower to higher concentration, reverse osmosis occurs.

Reverse osmosis will filter minerals, chemicals, and bacteria through carbon filters and membranes.

The Risks of Using Contaminated Water Without RO

There are different types of risks that come from drinking contaminated water. They differ depending on the nature of contamination and when you don’t use a reverse osmosis system, you’re probably in danger.

Common Types of Contamination

The most common types of contaminants are lead, nitrates and pesticides, and E. coli and other bacteria.

Lead gets into water from old pipes and through other places with poor infrastructure. This is particularly bad for pregnant women and children. Exposure to lead can lead to developmental problems and congenital disabilities.

Nitrates and pesticides come from fertilizers, herbicides, and pesticides. These types of water contaminants happen most often in farming areas. Nitrates are a primary cause of “blue baby syndrome” or methemoglobinemia.

  1. coli and other bacteria enter your water system through runoff and human waste. If you drink water contaminated with E. coli or other bacteria, you might experience nausea, stomach cramps. You could also experience diarrhea, and or vomiting.

In more severe cases, you can experience extreme dehydration, which can be lethal, kidney failure, or anemia.
