Reverse osmosis is a popular alternative to other forms of home water treatment or filtration options. Using the reverse osmosis process in your home can help improve the taste and odor of your tap water, making it safe enough for your family to drink. A reverse osmosis water filter is easy to install at your kitchen tap, refrigerator, or ice machine. At AquaThin NJ, we offer water filtration systems that use reverse osmosis to make your drinking water safer for your family. To help you understand why water filtration is important in your home, let’s discuss how the process works.

How Reverse Osmosis Works

Reverse osmosis is a natural water purification process that occurs when water is forced through a semipermeable membrane to remove a majority of contaminants from the water. This process requires pressure to force the water through the membrane while leaving the contaminants behind. Without the pressure, the water would simply pass through the membrane slowly. The amount of pressure required to filter the water depends on the concentration of contaminants. For instance, it takes much more pressure to remove the salt from seawater than it does to remove iron from tap water. A reverse osmosis membrane rejects contaminants based on the size and charge of the particles.

The Basic Components of Reverse Osmosis

While the size of the water filtration device and the number of filters may vary, reverse osmosis water filters all have the same components and operate similarly.

Reverse osmosis membrane:

is the semipermeable membrane, designed to remove contaminants.

Flow restrictor:

is the regulator that controls the flow rate of water through the membrane. The flow restrictor helps to maintain the pressure that is required for proper filtration.

Shut off valve:

allows you to turn the filter system off and let the water flow directly into the storage tank.

Storage tank:


typically holds between two and four gallons of filtered water that is accessible when you turn on your faucet. Because of the flow restrictor and the pressurized filtration method, it can slow or delay the flow of water out of the faucet.

What Contaminants Does Reverse Osmosis Water Filtration Remove?

The reverse osmosis process is capable of removing nearly all dissolved salts, particles, bacteria, and pyrogens from water. Examples of contaminants that are removed by residential reverse osmosis water filtration systems are algae, arsenic, bacteria, benzene, chloride, chlorine, copper, crypto, fluoride, lead, mercury, nitrates, pesticides, rust, salt, sulfates, and odors. Because reverse osmosis also removes calcium and magnesium from water, it can act as a water softener. However, it should be noted that if the water filter is used in lieu of a water softener, it will significantly reduce the lifespan of your water filter.

Reverse osmosis is not a new technology and has been used in residential settings since the late 1970s. It has continued to gain popularity because it is cost-effective and easy to maintain, in addition to making drinking water much safer for families. At Aquathin NJ, we are passionate about providing clean drinking water to all of our customers and their families.
