Clean drinking water is necessary for good health, but it's not always guaranteed that what flows from your tap is as pure as it should be. Contaminants, visible and invisible, can find their way into the water we use daily. This is where water filtration becomes crucial, and among the many methods available, reverse osmosis (RO) stands out as a highly effective way to purify water. In this blog, we’ll explore how reverse osmosis works and why it’s one of the best solutions for removing common water contaminants.

What is reverse osmosis?

Reverse osmosis is a water purification process that uses a semipermeable membrane to remove contaminants from water. It works by forcing water under pressure through a special membrane that filters out impurities at the molecular level. Only water molecules can pass through, while dissolved solids, chemicals, and other contaminants are left behind.

An reverse osmosis system typically consists of several components:

  • Pre-filters that capture larger particles.
  • The RO membrane itself.
  • Post-filters that polish the water.

This multi-stage process ensures that your water is as pure as possible.

Common water contaminants found in tap water

Common water contaminants found in tap water

Tap water may contain a variety of contaminants, some of which can pose health risks if consumed over time. Here are some of the most common ones:

  • Sediments like sand, rust, and dirt, are often caused by aging pipes.
  • Chlorine and chloramine, added to water to kill bacteria but affecting taste and health.
  • Lead, which can leach from old plumbing systems and pose serious health risks, particularly to children.
  • Fluoride, a controversial additive used for dental health but potentially harmful in excess.
  • Nitrates, typically from agricultural runoff, which can affect oxygen levels in the blood.
  • Arsenic, a toxic element sometimes found in groundwater.
  • Pesticides and herbicides, runoff from agricultural areas.
  • Bacteria and viruses, potentially present in untreated or poorly treated water.

Each contaminant can affect your health in various ways, from short-term symptoms like stomach issues to long-term problems like neurological damage or cancer.

How does reverse osmosis remove water contaminants?

Reverse osmosis tackles these contaminants through its layered filtration process. Here's how it deals with the most common ones:

  • Sediment filtration: The pre-filter traps large particles like dirt and rust, preventing them from clogging the more delicate RO membrane.
  • Carbon filtration: The next stage removes chlorine, chloramine, and volatile organic compounds (VOCs), which can affect water taste and pose health risks.
  • RO membrane: This is where the heavy lifting happens. The membrane is fine enough to block dissolved solids like fluoride, lead, nitrates, arsenic, and even certain bacteria and viruses. It’s designed to reduce Total Dissolved Solids (TDS), leaving only pure water behind.
  • Post-filtration: After passing through the RO membrane, the water passes through a final post-filter to ensure it tastes fresh and clean and removes any remaining impurities.

This multi-layered system means that reverse osmosis can remove up to 99% of harmful contaminants, making it one of the most thorough filtration methods available.

Benefits of reverse osmosis for home use

Benefits of reverse osmosis for home use

The benefits of using Glacier Fresh reverse osmosis system in your home go beyond just clean water. Here are some of the key advantages:

  • Pure, great-tasting drinking water: RO systems remove contaminants that affect the taste, leaving you with crisp, refreshing water.
  • Health benefits: Reverse osmosis can improve overall health by reducing exposure to harmful substances like lead, pesticides, and bacteria.
  • Environmental impact: Using an RO system reduces the consumption of bottled water, which helps reduce plastic waste.
  • Cost-effective: Although there’s an upfront investment, an RO system is far more cost-effective in the long run than constantly buying bottled water.

Reverse osmosis vs. other filtration method

When compared to other filtration methods like activated carbon filters, distillation, or ultraviolet (UV) purification, reverse osmosis stands out for its ability to remove a wider range of contaminants.

  • Activated carbon filters: These are great for removing chlorine, VOCs, and improving taste, but they can’t filter out dissolved solids or heavy metals like an RO system can.
  • Distillation: This method is effective but energy-intensive and doesn’t remove VOCs as efficiently as RO.
  • UV purification: While excellent for killing bacteria and viruses, UV systems don’t remove chemicals, metals, or sediments from water.

Overall, reverse osmosis offers a more comprehensive filtration solution, particularly for homes where water quality is a concern.

Maintenance and longevity of reverse osmosis systems

Regular maintenance is necessary to ensure your reverse osmosis system performs optimally. This typically includes changing pre-filters every 6 to 12 months and replacing the RO membrane every 2 to 3 years, depending on water quality and usage. Some signs that your system may need maintenance include a noticeable drop in water pressure or taste. With proper care, a reverse osmosis system can last many years, providing clean water for your household.

FAQs

Does RO remove beneficial minerals?

Yes, RO removes both harmful and beneficial minerals. However, most minerals you need for health come from food, not water, and you can always re-mineralize your water if desired.

Is RO water safe for pets and plants?

Yes, RO water is safe for pets and plants. However, depending on their specific needs, some plants may benefit from re-mineralized water.

Conclusion

Clean, safe drinking water is essential for your health, and reverse osmosis provides one of the most effective ways to achieve this. By removing common contaminants such as lead, nitrates, pesticides, and bacteria, an RO system ensures that the water you and your family consume is of the highest quality. Investing in a reverse osmosis system improves your water and can enhance your overall well-being. Visit Glacier Fresh to find more water filtration solutions.
