Upgrade Your Water Game: Exploring the Under Sink RO System

Understanding RO Systems

What is Reverse Osmosis?

Reverse osmosis (RO) is a water purification process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. During this process, the contaminants are filtered out and flushed away, leaving clean, delicious drinking water. RO is considered one of the most effective methods for filtering water and is utilized in a variety of settings, including residential homes, to provide high-quality drinking water (Fresh Water Systems).

The process begins when pressure is applied to a volume of water, such as saltwater. As the water is pushed through the membrane, the larger molecules, including salts and other impurities, are unable to pass through these tiny pores and are left behind. Consequently, only pure water is allowed to flow through the other side of the membrane. This method is highly effective at reducing various contaminants, making it a popular choice for residential RO systems.

Components of an RO System

An under sink RO system typically comprises multiple stages of filtration to ensure comprehensive water purification. Each RO system includes at least the following components:

1. Sediment Filter: This filter is responsible for removing particles such as dirt, dust, and rust, which can affect the appearance and overall quality of your water.
2. Carbon Filter: Often, there are one or two carbon filters used in an RO system that work to reduce elements like chlorine, which can cause bad taste and odors in the water.
3. Reverse Osmosis Membrane: The critical component of the system, the RO membrane, has tiny pores that allow water to pass through while trapping a majority of dissolved solids that are too large to pass through the pores.
4. Drain Line: This line expels the contaminants and impurities from the RO system.
5. Storage Tank: RO systems come with a storage tank where purified water is kept until you need it.
6. Faucet: An RO system usually includes a dedicated faucet that is installed on your sink for dispensing the filtered water.
7. Post Filter(s): Before the water flows through the faucet, it often passes through one more post-filter to polish the drinking water and remove any residual taste or odor.

The RO system could waste approximately four gallons of water for every gallon of purified water produced. The wastewater, containing the rejected contaminants, is sent down a drain line. This ratio is important as it relates to the system’s efficiency, and efforts should be made to reduce water waste.

Maintaining an RO system requires regular replacement of its filters and membrane. Prefilters and postfilters should be replaced every 6 months to 1 year, and the RO membrane every 2-4 years to ensure the system’s effectiveness and longevity.
